Israel
–
Israel, officially the State of Israel, is a country in the Middle East, on the southeastern shore of the Mediterranean Sea and the northern shore of the Red Sea. The country contains geographically diverse features within its small area. Israels economy and technology center is Tel Aviv, while its seat of government and proclaimed capital is Jerusalem, in 1947, the United Nations adopted a Partition Plan for Mandatory Palestine recommending the creation of independent Arab and Jewish states and an internationalized Jerusalem. The plan was accepted by the Jewish Agency for Palestine, next year, the Jewish Agency declared the establishment of a Jewish state in Eretz Israel, to be known as the State of Israel. Israel has since fought several wars with neighboring Arab states, in the course of which it has occupied territories including the West Bank, Golan Heights and it extended its laws to the Golan Heights and East Jerusalem, but not the West Bank. Israels occupation of the Palestinian territories is the worlds longest military occupation in modern times, efforts to resolve the Israeli–Palestinian conflict have not resulted in peace. However, peace treaties between Israel and both Egypt and Jordan have successfully been signed, the population of Israel, as defined by the Israel Central Bureau of Statistics, was estimated in 2017 to be 8,671,100 people. It is the worlds only Jewish-majority state, with 74. 8% being designated as Jewish, the countrys second largest group of citizens are Arabs, at 20. 8%. The great majority of Israeli Arabs are Sunni Muslims, including significant numbers of semi-settled Negev Bedouins, other minorities include Arameans, Armenians, Assyrians, Black Hebrew Israelites, Circassians, Maronites and Samaritans. Israel also hosts a significant population of foreign workers and asylum seekers from Africa and Asia, including illegal migrants from Sudan, Eritrea. In its Basic Laws, Israel defines itself as a Jewish, Israel is a representative democracy with a parliamentary system, proportional representation and universal suffrage. The prime minister is head of government and the Knesset is the legislature, Israel is a developed country and an OECD member, with the 35th-largest economy in the world by nominal gross domestic product as of 2016. The country benefits from a skilled workforce and is among the most educated countries in the world with one of the highest percentage of its citizens holding a tertiary education degree. The country has the highest standard of living in the Middle East and the third highest in Asia, in the early weeks of independence, the government chose the term Israeli to denote a citizen of Israel, with the formal announcement made by Minister of Foreign Affairs Moshe Sharett. The names Land of Israel and Children of Israel have historically used to refer to the biblical Kingdom of Israel. The name Israel in these phrases refers to the patriarch Jacob who, jacobs twelve sons became the ancestors of the Israelites, also known as the Twelve Tribes of Israel or Children of Israel. The earliest known artifact to mention the word Israel as a collective is the Merneptah Stele of ancient Egypt. The area is known as the Holy Land, being holy for all Abrahamic religions including Judaism, Christianity, Islam

Jordan
–
Jordan, officially The Hashemite Kingdom of Jordan, is an Arab kingdom in Western Asia, on the East Bank of the Jordan River. Jordan is bordered by Saudi Arabia to the east and south, Iraq to the north-east, Syria to the north, Israel, Palestine and the Dead Sea to the west, Jordan is strategically located at the crossroads of Asia, Africa and Europe. The capital, Amman, is Jordans most populous city as well as the countrys economic, what is now Jordan has been inhabited by humans since the Paleolithic period. Three stable kingdoms emerged there at the end of the Bronze Age, Ammon, Moab, later rulers include the Nabataean Kingdom, the Roman Empire, and the Ottoman Empire. After the Great Arab Revolt against the Ottomans in 1916 during World War I, the Emirate of Transjordan was established in 1921 by the then Emir Abdullah I and became a British protectorate. In 1946, Jordan became an independent state known as The Hashemite Kingdom of Transjordan. Jordan captured the West Bank, which it later lost in 1967, during the 1948 Arab–Israeli War, Jordan is a founding member of the Arab League and the Organisation of Islamic Cooperation, and is one of two Arab states to have signed a peace treaty with Israel. The country is a monarchy, but the king holds wide executive and legislative powers. Jordan is a relatively-small, semi-arid, almost-landlocked country with a population numbering at 9.5 million, Sunni Islam, practiced by around 92% of the population, is the dominant religion in Jordan. It coexists with an indigenous Christian minority, Jordan is considered to be among the safest of Arab countries in the Middle East, and has avoided long-term terrorism and instability. The kingdom is also a refuge to thousands of Iraqi Christians fleeing the Islamic State, while Jordan continues to accept refugees, the recent large influx from Syria placed substantial strain on national resources and infrastructure. Jordan is classified as a country of high human development with a middle income economy. The Jordanian economy, one of the smallest economies in the region, is attractive to foreign investors based upon a skilled workforce, the country is a major tourist destination, and also attracts medical tourism due to its well developed health sector. Nonetheless, a lack of resources, large flow of refugees. Jordan is named after the Jordan River, where Jesus is said to have been baptized, the origin of the rivers name is debated, but the most common explanation is that it derives from the word yarad, found in Hebrew, Aramaic, and other Semitic languages. Others regard the name as having an Indo-Aryan origin, combining the words yor and don, another theory is that it is from the Arabic root word wrd, as in people coming to a major source of water. The name Jordan appears in an ancient Egyptian papyrus called Papyrus Anastasi I, the lands of modern-day Jordan were historically called Transjordan, meaning beyond the Jordan River. The name was Arabized into Al-Urdunn during the Muslim conquest of the Levant, during crusader rule, it was called Oultrejordain

State of Palestine
–
The State of Palestine claims the West Bank and Gaza Strip with East Jerusalem as the designated capital. Most of the areas claimed by the State of Palestine have been occupied by Israel since 1967 in the aftermath of the Six-Day War and its independence was declared on 15 November 1988 by the Palestine Liberation Organization in Algiers as a government-in-exile. Since the British Mandate, the term Palestine has been associated with the area that currently covers the State of Israel, the West Bank. In 1947, the UN adopted a plan for a two-state solution in the remaining territory of the mandate. The plan was accepted by the Jewish leadership but rejected by the Arab leaders, on the eve of final British withdrawal, the Jewish Agency for Israel declared the establishment of the State of Israel according to the proposed UN plan. During the war, Israel gained additional territories that were designated to be part of the Arab state under the UN plan, Egypt occupied the Gaza Strip and Transjordan occupied the West Bank. Egypt initially supported the creation of an All-Palestine Government, but disbanded it in 1959, Transjordan never recognized it and instead decided to incorporate the West Bank with its own territory to form Jordan. The annexation was ratified in 1950 but was rejected by the international community, the Six-Day War in 1967, when Egypt, Jordan, and Syria fought against Israel, ended with Israel being in occupation of the West Bank and Gaza Strip, besides other territories. In 1964, when the West Bank was controlled by Jordan, the Palestinian National Charter of the PLO defines the boundaries of Palestine as the whole remaining territory of the mandate, including Israel. Following the Six-Day War, the PLO moved to Jordan, the October 1974 Arab League summit designated the PLO as the sole legitimate representative of the Palestinian people and reaffirmed their right to establish an independent state of urgency. In November 1974, the PLO was recognized as competent on all matters concerning the question of Palestine by the UN General Assembly granting them observer status as an entity at the UN. In spite of this decision, the PLO did not participate at the UN in its capacity of the State of Palestines government, in 1979, through the Camp David Accords, Egypt signaled an end to any claim of its own over the Gaza Strip. In July 1988, Jordan ceded its claims to the West Bank—with the exception of guardianship over Haram al-Sharif—to the PLO, in November 1988, the PLO legislature, while in exile, declared the establishment of the State of Palestine. In the month following, it was recognised by many states, including Egypt. In the Palestinian Declaration of Independence, the State of Palestine is described as being established on the Palestinian territory, the UN membership application submitted by the State of Palestine also specified that it is based on the 1967 borders. During the negotiations of the Oslo Accords, the PLO recognised Israels right to exist, after Israel took control of the West Bank from Jordan and Gaza Strip from Egypt, it began to establish Israeli settlements there. These were organised into Judea and Samaria district and Hof Aza Regional Council in the Southern District, in 1980, Israel decided to freeze elections for these councils and to establish instead Village Leagues, whose officials were under Israeli influence. Later this model became ineffective for both Israel and the Palestinians, and the Village Leagues began to break up, with the last being the Hebron League, dissolved in February 1988

Geographic coordinate system
–
A geographic coordinate system is a coordinate system used in geography that enables every location on Earth to be specified by a set of numbers, letters or symbols. The coordinates are chosen such that one of the numbers represents a vertical position. A common choice of coordinates is latitude, longitude and elevation, to specify a location on a two-dimensional map requires a map projection. The invention of a coordinate system is generally credited to Eratosthenes of Cyrene. Ptolemy credited him with the adoption of longitude and latitude. Ptolemys 2nd-century Geography used the prime meridian but measured latitude from the equator instead. Mathematical cartography resumed in Europe following Maximus Planudes recovery of Ptolemys text a little before 1300, in 1884, the United States hosted the International Meridian Conference, attended by representatives from twenty-five nations. Twenty-two of them agreed to adopt the longitude of the Royal Observatory in Greenwich, the Dominican Republic voted against the motion, while France and Brazil abstained. France adopted Greenwich Mean Time in place of local determinations by the Paris Observatory in 1911, the latitude of a point on Earths surface is the angle between the equatorial plane and the straight line that passes through that point and through the center of the Earth. Lines joining points of the same latitude trace circles on the surface of Earth called parallels, as they are parallel to the equator, the north pole is 90° N, the south pole is 90° S. The 0° parallel of latitude is designated the equator, the plane of all geographic coordinate systems. The equator divides the globe into Northern and Southern Hemispheres, the longitude of a point on Earths surface is the angle east or west of a reference meridian to another meridian that passes through that point. All meridians are halves of great ellipses, which converge at the north and south poles, the prime meridian determines the proper Eastern and Western Hemispheres, although maps often divide these hemispheres further west in order to keep the Old World on a single side. The antipodal meridian of Greenwich is both 180°W and 180°E, the combination of these two components specifies the position of any location on the surface of Earth, without consideration of altitude or depth. The grid formed by lines of latitude and longitude is known as a graticule, the origin/zero point of this system is located in the Gulf of Guinea about 625 km south of Tema, Ghana. To completely specify a location of a feature on, in, or above Earth. Earth is not a sphere, but a shape approximating a biaxial ellipsoid. It is nearly spherical, but has an equatorial bulge making the radius at the equator about 0. 3% larger than the radius measured through the poles, the shorter axis approximately coincides with the axis of rotation

Lake
–
A lake is an area of variable size filled with water, localized in a basin, that is surrounded by land, apart from any river or other outlet that serves to feed or drain the lake. Lakes lie on land and are not part of the ocean, and therefore are distinct from lagoons, Lakes can be contrasted with rivers or streams, which are usually flowing. Most lakes are fed and drained by rivers and streams, natural lakes are generally found in mountainous areas, rift zones, and areas with ongoing glaciation. Other lakes are found in endorheic basins or along the courses of mature rivers, in some parts of the world there are many lakes because of chaotic drainage patterns left over from the last Ice Age. All lakes are temporary over geologic time scales, as they will fill in with sediments or spill out of the basin containing them. The word lake comes from Middle English lake, from Old English lacu, from Proto-Germanic *lakō, cognates include Dutch laak, Middle Low German lāke as in, de, Moorlake, de, Wolfslake, de, Butterlake, German Lache, and Icelandic lækur. Also related are the English words leak and leach, none of these definitions completely excludes ponds and all are difficult to measure. For this reason, simple size-based definitions are used to separate ponds. One definition of lake is a body of water of 2 hectares or more in area, however, others have defined lakes as waterbodies of 5 hectares and above, or 8 hectares and above. Charles Elton, one of the founders of ecology, regarded lakes as waterbodies of 40 hectares or more. The term lake is used to describe a feature such as Lake Eyre. In common usage, many bear names ending with the word pond. One textbook illustrates this point with the following, In Newfoundland, for example, almost every lake is called a pond, whereas in Wisconsin, the majority of lakes on Earth are fresh water, and most lie in the Northern Hemisphere at higher latitudes. Canada, with a drainage system has an estimated 31,752 lakes larger than 3 square kilometres and an unknown total number of lakes. Finland has 187,888 lakes 500 square metres or larger, most lakes have at least one natural outflow in the form of a river or stream, which maintain a lakes average level by allowing the drainage of excess water. Some lakes do not have an outflow and lose water solely by evaporation or underground seepage or both. Many lakes are artificial and are constructed for power generation, aesthetic purposes, recreational purposes, industrial use. Globally, lakes are greatly outnumbered by ponds, of an estimated 304 million standing water bodies worldwide, 91% are 1 hectare or less in area

Endorheic basin
–
Such a basin may also be referred to as a closed or terminal basin or as an internal drainage system. However, in a basin, rain that falls within it does not flow out but may only leave the drainage system by evaporation. The bottom of such a basin is occupied by a salt lake or salt pan. Endorheic regions, in contrast to regions which flow to the ocean in geologically defined patterns, are closed hydrologic systems. Their surface waters drain to inland terminal locations where the water evaporates or seeps into the ground, endorheic water bodies include some of the largest lakes in the world, such as the Aral Sea and the Caspian Sea, the worlds largest saline inland sea. Most endorheic basins are arid, although there are notable exceptions, such as the Valley of Mexico, the Lake Tahoe region. Endorheic basins can be massively and rapidly affected by change and excessive water removal. An exorheic lake naturally remains at a level, so water flow into the lake may be many times more than is needed to maintain its present size. In contrast, an endorheic basin does not have enough inflow that it overflows to the ocean, endorheic lakes are bodies of water that do not flow into the sea. Most of the water falling on Earth finds its way to the oceans through a network of rivers, lakes, however, there is a class of water bodies that are located in closed or endorheic watersheds where the topography prevents their drainage to the oceans. These endorheic watersheds are often called terminal lakes or sink lakes, endorheic lakes are usually in the interior of a landmass, far from an ocean in areas of relatively low rainfall. Their watersheds are often confined by natural geologic land formations such as a mountain range, the inland water flows into dry watersheds where the water evaporates, leaving a high concentration of minerals and other inflow erosion products. Over time this input of erosion products can cause the lake to become relatively saline. Endorheic regions can occur in any climate but are most commonly found in desert locations, the Black Sea was likely such a lake, having once been an independent hydrological system before the Mediterranean Sea broke through the terrain separating the two. Lake Bonneville was another such lake, overflowing its basin in the Bonneville flood, malheur/Harney Lake in Oregon is normally cut off from drainage to the ocean, but has an outflow channel to the Malheur River that is normally dry, but flows in years of peak precipitation. Examples of relatively humid regions in endorheic basins often exist at high elevation and these regions tend to be marshy and are subject to substantial flooding in wet years. The area containing Mexico City is one case, with annual precipitation of 850 mm. Endorheic regions tend to be far inland with their boundaries defined by mountains or other features that block their access to oceans

Hypersaline lake
–
A hypersaline lake is a landlocked body of water that contains significant concentrations of sodium chloride or other salts, with saline levels surpassing that of ocean water. Specific microbial and crustacean species thrive in high salinity environments that are inhospitable to most lifeforms. Some of these species enter a dormant state when desiccated, the water of hypersaline lakes has great buoyancy due to a high salt content. The most saline water body in the world is the Don Juan Pond and its volume is some 3,000 cubic meters, but is constantly changing. The Don Juan Pond has a salinity level of over 44% and its high salinity prevents the Don Juan from freezing even when temperatures are below −50 °C. There are larger water bodies, lakes in the McMurdo Dry Valleys such as Lake Vanda with salinity of over 35%. They are covered with ice in the winter, the most saline lake outside of Antarctica is Lake Assal, in Djibouti, which has a salinity of 34. 8%. Probably the best-known hypersaline lakes are the Dead Sea and the Great Salt Lake, the Dead Sea, dividing Israel and the Palestinian West Bank from Jordan, is the worlds deepest hypersaline lake and the Araruama Lagoon is the worlds largest hypersaline lake. The Great Salt Lake, located in Utah, while having three times the surface area of the Dead Sea, is shallower and experiences much greater fluctuations in level than the Dead Sea. At its lowest recorded levels, it approaches 7.7 times the salinity of ocean water, hypersaline lakes are found on every continent, especially in arid or semi-arid regions.

Inflow (hydrology)
–
In hydrology, the inflow of a body of water is the source of the water in the body of water. It can also refer to the volume of incoming water in unit time. All bodies of water have multiple inflows, but often, one inflow may predominate, however, in many cases, no single inflow will predominate and there will be multiple primary inflows. For a lake, the inflow may be a river or stream that flows into the lake. Inflow may also be, strictly speaking, not flows, but rather precipitation, inflow can also be used to refer to groundwater recharge. The dictionary definition of inflow at Wiktionary

Jordan River
–
The Jordan River is a 251-kilometre -long river in the Middle East that flows roughly north to south through the Sea of Galilee and on to the Dead Sea. Israel and the West Bank border the river to the west, while the Golan Heights, both Jordan and the West Bank take their names from the river. The Jordan River has a course and a lower one. In this sense, the Jordan Valley may be separated into upper, central, over its upper course, the river drops rapidly in a 75-kilometre run to the once large and swampy Lake Hula, which is slightly above sea level. Exiting the now much diminished lake, it goes through an even steeper drop over the 25 kilometres down to the Sea of Galilee, the Jordan deposits much of the silt it is carrying within the lake, which it leaves again near its southern tip. At that point the river is situated about 210 metres below sea level, two major tributaries enter from the east during this last section, the Yarmouk River and Zarqa River. Its section north of the Sea of Galilee is within the boundaries of Israel, south of the lake, it forms the border between the Kingdom of Jordan, and Israel. The streams coming together to create the River Jordan in its basin are, west to east, Iyyon. Hasbani, a stream flows from Mount Lebanon. Dan, a stream whose source is also at the base of Mount Hermon, Banias, a stream arising from a spring at Banias at the foot of Mount Hermon. The full text of W. F. Lynchs 1849 book Narrative of the United States Expedition to the River Jordan, in 1964, Israel began operating a pumping station that diverts water from the Sea of Galilee to the National Water Carrier. Also in 1964, Jordan constructed a channel that diverted water from the Yarmouk River, another tributary of the Jordan River to the East Ghor Canal. Syria has also built reservoirs that catch the Yarmouks waters, environmentalists blame Israel, Jordan and Syria for extensive damage to the Jordan River ecosystem. In modern times, the waters are 70% to 90% used for human purposes, because of this and the high evaporation rate of the Dead Sea, as well as industrial extraction of salts through evaporation ponds, the sea is shrinking. All the shallow waters of the end of the sea have been drained in modern times and are now salt flats. A small section of the northernmost portion of the Lower Jordan, 3-kilometre below the Sea of Galilee, has been kept pristine for baptism and local tourism. Most polluted is the 100-kilometre downstream stretch—a meandering stream from above the confluence with the Yarmouk to the Dead Sea, environmentalists say the practice of letting sewage and brackish water flow into the river has almost destroyed its ecosystem. Rescuing the Jordan could take decades, according to environmentalists, the same environmentalist organization had said in a report that the Jordan River could dry up by 2011 unless the decay is stopped
10.
Discharge (hydrology)
–
In hydrology, discharge is the volume rate of water flow that is transported through a given cross-sectional area. It includes any suspended solids, dissolved chemicals, or biologic material in addition to the water itself, GH Dury and MJ Bradshaw are two hydrologists who devised the models showing the relationship between discharge and other variables in a river. The units that are used to express discharge include m³/s, ft³/s and/or acre-feet per day. For example, the discharge of the Rhine river in Europe is 2,200 cubic metres per second or 190,000,000 cubic metres per day. A commonly applied methodology for measuring, and estimating, the discharge of a river is based on a form of the continuity equation. In storm hydrology, an important consideration is the streams discharge hydrograph, the stream rises to a peak flow after each precipitation event, then falls in a slow recession. Because the peak flow also corresponds to the water level reached during the event. The amount of precipitation correlates to the volume of water that flows out of the river. The relationship between the discharge in the stream at a given cross-section and the level of the stream is described by a rating curve, average velocities and the cross-sectional area of the stream are measured for a given stream level. The velocity and the give the discharge for that level. After measurements are made for different levels, a rating table or rating curve may be developed. Once rated, the discharge in the stream may be determined by measuring the level, if a continuous level-recording device is located at a rated cross-section, the streams discharge may be continuously determined. Larger flows can transport more sediment and larger particles downstream than smaller flows due to their greater force, larger flows can also erode stream banks and damage public infrastructure
11.
Drainage basin
–
A drainage basin or catchment area is any area of land where precipitation collects and drains off into a common outlet, such as into a river, bay, or other body of water. Drainage basins connect into other drainage basins at elevations in a hierarchical pattern, with smaller sub-drainage basins. Other terms used to describe drainage basins are catchment, catchment basin, drainage area, river basin and water basin. In closed drainage basins the water converges to a point inside the basin, known as a sink, which may be a permanent lake. The drainage basin acts as a funnel by collecting all the water within the covered by the basin. Each drainage basin is separated topographically from adjacent basins by a perimeter, drainage basins are similar but not identical to hydrologic units, which are drainage areas delineated so as to nest into a multi-level hierarchical drainage system. Hydrologic units are defined to allow multiple inlets, outlets, or sinks, in a strict sense, all drainage basins are hydrologic units but not all hydrologic units are drainage basins. Drainage basins of the oceans and seas of the world. Grey areas are endorheic basins that do not drain to the oceans, the following is a list of the major ocean basins, About 48. 7% of the worlds land drains to the Atlantic Ocean. The two major mediterranean seas of the world also flow to the Atlantic, The Caribbean Sea and Gulf of Mexico basin includes most of the U. S. The Mediterranean Sea basin includes much of North Africa, east-central Africa, Southern, Central, and Eastern Europe, Turkey, and the areas of Israel, Lebanon. Just over 13% of the land in the world drains to the Pacific Ocean, the Indian Oceans drainage basin also comprises about 13% of Earths land. It drains the eastern coast of Africa, the coasts of the Red Sea and the Persian Gulf, the Indian subcontinent, Burma, antarctica comprises approximately eight percent of the Earths land. The five largest river basins, from largest to smallest, are the basins of the Amazon, the Río de la Plata, the Congo, the Nile, and the Mississippi. The three rivers that drain the most water, from most to least, are the Amazon, Ganga, endorheic drainage basins are inland basins that do not drain to an ocean. Around 18% of all land drains to endorheic lakes or seas or sinks, the largest of these consists of much of the interior of Asia, which drains into the Caspian Sea, the Aral Sea, and numerous smaller lakes. Some of these, such as the Great Basin, are not single drainage basins but collections of separate, in endorheic bodies of standing water where evaporation is the primary means of water loss, the water is typically more saline than the oceans. An extreme example of this is the Dead Sea, drainage basins have been historically important for determining territorial boundaries, particularly in regions where trade by water has been important

Coastline paradox
–
The coastline paradox is the counterintuitive observation that the coastline of a landmass does not have a well-defined length. This results from the properties of coastlines. The first recorded observation of this phenomenon was by Lewis Fry Richardson, more concretely, the length of the coastline depends on the method used to measure it. Various approximations exist when specific assumptions are made about minimum feature size, the basic concept of length originates from Euclidean distance. In the familiar Euclidean geometry, a straight line represents the shortest distance between two points, this line has only one length, the length of basic curves is more complicated but can also be calculated. Using shorter and shorter lines will produce sums that approach the true length. A precise value for this length can be established using calculus, the following animation illustrates how a smooth curve can be meaningfully assigned a precise length, However, not all curves can be measured in this way. A fractal is by definition a curve whose complexity changes with measurement scale, whereas approximations of a smooth curve get closer and closer to a single value as measurement precision increases, the measured value of fractals may change wildly. However, this relies on the assumption that space can be subdivided indefinitely. The Planck length, many orders of magnitude smaller than an atom, is proposed as the smallest measurable unit possible in the universe, coastlines differ from mathematical fractals because they are formed by numerous small events, which create patterns only statistically. In reality, permanent features of the coastline of order of size 1 cm or less do not exist, because of erosion, in most places the minimum size is much larger than this. Thus the concept of a fractal is not applicable to the coastline. For practical considerations, a choice of minimum feature size is on the order of the units being used to measure. If a coastline is measured in kilometers, then small variations much smaller than one kilometer are easily ignored, to measure the coastline in centimeters, tiny variations the size of centimeters must be considered. Using different measurement methodologies for different units also destroys the usual certainty that units can be converted by a simple multiplication, extreme cases of the coastline paradox include the fjord-heavy coastlines of Norway, Chile and the Pacific Northwest of North America.

Hebrew language
–
Hebrew is a language native to Israel, spoken by over 9 million people worldwide, of whom over 5 million are in Israel. Historically, it is regarded as the language of the Israelites and their ancestors, the earliest examples of written Paleo-Hebrew date from the 10th century BCE. Hebrew belongs to the West Semitic branch of the Afroasiatic language family, Hebrew is the only living Canaanite language left, and the only truly successful example of a revived dead language. Hebrew had ceased to be a spoken language somewhere between 200 and 400 CE, declining since the aftermath of the Bar Kokhba revolt. Aramaic and to a lesser extent Greek were already in use as international languages, especially among elites and it survived into the medieval period as the language of Jewish liturgy, rabbinic literature, intra-Jewish commerce, and poetry. Then, in the 19th century, it was revived as a spoken and literary language, and, according to Ethnologue, had become, as of 1998, the language of 5 million people worldwide. After Israel, the United States has the second largest Hebrew-speaking population, with 220,000 fluent speakers, Modern Hebrew is one of the two official languages of the State of Israel, while premodern Hebrew is used for prayer or study in Jewish communities around the world today. Ancient Hebrew is also the tongue of the Samaritans, while modern Hebrew or Arabic is their vernacular. For this reason, Hebrew has been referred to by Jews as Leshon Hakodesh, the modern word Hebrew is derived from the word Ivri, one of several names for the Israelite people. It is traditionally understood to be a based on the name of Abrahams ancestor, Eber. This name is based upon the root ʕ-b-r meaning to cross over. Interpretations of the term ʕibrim link it to this verb, cross over, in the Bible, the Hebrew language is called Yәhudit because Judah was the surviving kingdom at the time of the quotation. In Isaiah 19,18 it is called the Language of Canaan, Hebrew belongs to the Canaanite group of languages. In turn, the Canaanite languages are a branch of the Northwest Semitic family of languages, according to Avraham ben-Yosef, Hebrew flourished as a spoken language in the Kingdoms of Israel and Judah during about 1200 to 586 BCE. Scholars debate the degree to which Hebrew was a vernacular in ancient times following the Babylonian exile. In July 2008 Israeli archaeologist Yossi Garfinkel discovered a ceramic shard at Khirbet Qeiyafa which he claimed may be the earliest Hebrew writing yet discovered, dating around 3000 years ago. The Gezer calendar also dates back to the 10th century BCE at the beginning of the Monarchic Period, classified as Archaic Biblical Hebrew, the calendar presents a list of seasons and related agricultural activities. The Gezer calendar is written in an old Semitic script, akin to the Phoenician one that through the Greeks, the Gezer calendar is written without any vowels, and it does not use consonants to imply vowels even in the places where later Hebrew spelling requires it

Arabic
–
Arabic is a Central Semitic language that was first spoken in Iron Age northwestern Arabia and is now the lingua franca of the Arab world. Arabic is also the language of 1.7 billion Muslims. It is one of six languages of the United Nations. The modern written language is derived from the language of the Quran and it is widely taught in schools and universities, and is used to varying degrees in workplaces, government, and the media. The two formal varieties are grouped together as Literary Arabic, which is the language of 26 states. Modern Standard Arabic largely follows the standards of Quranic Arabic. Much of the new vocabulary is used to denote concepts that have arisen in the post-Quranic era, Arabic has influenced many languages around the globe throughout its history. During the Middle Ages, Literary Arabic was a vehicle of culture in Europe, especially in science, mathematics. As a result, many European languages have borrowed many words from it. Many words of Arabic origin are found in ancient languages like Latin. Balkan languages, including Greek, have acquired a significant number of Arabic words through contact with Ottoman Turkish. Arabic has also borrowed words from languages including Greek and Persian in medieval times. Arabic is a Central Semitic language, closely related to the Northwest Semitic languages, the Ancient South Arabian languages, the Semitic languages changed a great deal between Proto-Semitic and the establishment of the Central Semitic languages, particularly in grammar. Innovations of the Central Semitic languages—all maintained in Arabic—include, The conversion of the suffix-conjugated stative formation into a past tense, the conversion of the prefix-conjugated preterite-tense formation into a present tense. The elimination of other prefix-conjugated mood/aspect forms in favor of new moods formed by endings attached to the prefix-conjugation forms, the development of an internal passive. These features are evidence of descent from a hypothetical ancestor. In the southwest, various Central Semitic languages both belonging to and outside of the Ancient South Arabian family were spoken and it is also believed that the ancestors of the Modern South Arabian languages were also spoken in southern Arabia at this time. To the north, in the oases of northern Hijaz, Dadanitic and Taymanitic held some prestige as inscriptional languages, in Najd and parts of western Arabia, a language known to scholars as Thamudic C is attested

Sea level
–
Mean sea level is an average level of the surface of one or more of Earths oceans from which heights such as elevations may be measured. A common and relatively straightforward mean sea-level standard is the midpoint between a low and mean high tide at a particular location. Sea levels can be affected by factors and are known to have varied greatly over geological time scales. The careful measurement of variations in MSL can offer insights into ongoing climate change, the term above sea level generally refers to above mean sea level. Precise determination of a sea level is a difficult problem because of the many factors that affect sea level. Sea level varies quite a lot on several scales of time and this is because the sea is in constant motion, affected by the tides, wind, atmospheric pressure, local gravitational differences, temperature, salinity and so forth. The easiest way this may be calculated is by selecting a location and calculating the mean sea level at that point, for example, a period of 19 years of hourly level observations may be averaged and used to determine the mean sea level at some measurement point. One measures the values of MSL in respect to the land, hence a change in MSL can result from a real change in sea level, or from a change in the height of the land on which the tide gauge operates. In the UK, the Ordnance Datum is the sea level measured at Newlyn in Cornwall between 1915 and 1921. Prior to 1921, the datum was MSL at the Victoria Dock, in Hong Kong, mPD is a surveying term meaning metres above Principal Datum and refers to height of 1. 230m below the average sea level. In France, the Marégraphe in Marseilles measures continuously the sea level since 1883 and it is used for a part of continental Europe and main part of Africa as official sea level. Elsewhere in Europe vertical elevation references are made to the Amsterdam Peil elevation, satellite altimeters have been making precise measurements of sea level since the launch of TOPEX/Poseidon in 1992. A joint mission of NASA and CNES, TOPEX/Poseidon was followed by Jason-1 in 2001, height above mean sea level is the elevation or altitude of an object, relative to the average sea level datum. It is also used in aviation, where some heights are recorded and reported with respect to sea level, and in the atmospheric sciences. An alternative is to base height measurements on an ellipsoid of the entire Earth, in aviation, the ellipsoid known as World Geodetic System 84 is increasingly used to define heights, however, differences up to 100 metres exist between this ellipsoid height and mean tidal height. The alternative is to use a vertical datum such as NAVD88. When referring to geographic features such as mountains on a topographic map, the elevation of a mountain denotes the highest point or summit and is typically illustrated as a small circle on a topographic map with the AMSL height shown in metres, feet or both. In the rare case that a location is below sea level, for one such case, see Amsterdam Airport Schiphol

Salinity
–
Salinity is the saltiness or amount of salt dissolved in a body of water. This is usually measured in g salt k g sea water, a contour line of constant salinity is called an isohaline – or sometimes isohale. Salinity in rivers, lakes, and the ocean is conceptually simple, conceptually the salinity is the quantity of dissolved salt content of the water. Salts are compounds like sodium chloride, magnesium sulfate, potassium nitrate, the concentration of dissolved chloride ions is sometimes referred to as chlorinity. Operationally, dissolved matter is defined as that which can pass through a fine filter. Salinity can be expressed in the form of a mass fraction, Seawater typically has a mass salinity of around 35 g/kg, although lower values are typical near coasts where rivers enter the ocean. Rivers and lakes can have a range of salinities, from less than 0.01 g/kg to a few g/kg. The Dead Sea has a salinity of more than 200 g/kg, whatever pore size is used in the definition, the resulting salinity value of a given sample of natural water will not vary by more than a few percent. A bottled seawater product known as IAPSO Standard Seawater is used by oceanographers to standardize their measurements with enough precision to meet this requirement, measurement and definition difficulties arise because natural waters contain a complex mixture of many different elements from different sources in different molecular forms. The chemical properties of some of these depend on temperature and pressure. Many of these forms are difficult to measure with high accuracy, different practical definitions of salinity result from different attempts to account for these problems, to different levels of precision, while still remaining reasonably easy to use. For many purposes this sum can be limited to a set of eight major ions in natural waters, the major ions dominate the inorganic composition of most natural waters. Exceptions include some pit lakes and waters from some hydrothermal springs, the concentrations of dissolved gases like oxygen and nitrogen are not usually included in descriptions of salinity. However, carbon dioxide gas, which when dissolved is partially converted into carbonates and bicarbonates, is often included. Silicon in the form of acid, which usually appears as a neutral molecule in the pH range of most natural waters. The term salinity is, for oceanographers, usually associated with one of a set of measurement techniques. As the dominant techniques evolve, so do different descriptions of salinity, the distinctions between these different descriptions are important to physical oceanographers but are obscure and confusing to nonspecialists. Salinities were largely measured using titration-based techniques before the 1980s, titration with silver nitrate could be used to determine the concentration of halide ions to give a chlorinity

Seawater
–
Seawater, or salt water, is water from a sea or ocean. On average, seawater in the oceans has a salinity of about 3. 5% This means that every kilogram of seawater has approximately 35 grams of dissolved salts. Average density at the surface is 1.025 kg/l, seawater is denser than both fresh water and pure water because the dissolved salts increase the mass by a larger proportion than the volume. The freezing point of seawater decreases as salt concentration increases, at typical salinity, it freezes at about −2 °C. The coldest seawater ever recorded was in 2010, in a stream under an Antarctic glacier, seawater pH is typically limited to a range between 7.5 and 8.4. However, there is no universally accepted reference pH-scale for seawater, although the vast majority of seawater has a salinity of between 31 g/kg and 38 g/kg, seawater is not uniformly saline throughout the world. Where mixing occurs with fresh water runoff from river mouths, near melting glaciers or vast amounts precipitation, the most saline open sea is the Red Sea, where high rates of evaporation, low precipitation and low river run-off, and confined circulation result in unusually salty water. The salinity in isolated bodies of water can be considerably greater still, historically, several salinity scales were used to approximate the absolute salinity of seawater. A popular scale was the Practical Salinity Scale where salinity was measured in practical salinity units, the current standard for salinity is the Reference Salinity scale with the salinity expressed in units of g/kg. The density of surface seawater ranges from about 1020 to 1029 kg/m3, depending on the temperature, at a temperature of 25 °C, salinity of 35 g/kg and 1 atm pressure, the density of seawater is 1023.6 kg/m3. Deep in the ocean, under pressure, seawater can reach a density of 1050 kg/m3 or higher. The density of seawater also changes with salinity, brines generated by seawater desalination plants can have salinities up to 120 g/kg. The density of typical seawater brine of 120 g/kg salinity at 25 °C, seawater pH is limited to the range 7.5 to 8.4. The speed of sound in seawater is about 1,500 m/s, and varies with temperature, salinity. The thermal conductivity of seawater is 0.6 W/mK at 25 °C, the thermal conductivity decreases with increasing salinity and increases with increasing temperature. Seawater contains more dissolved ions than all types of freshwater, however, the ratios of solutes differ dramatically. Bicarbonate ions also constitute 48% of river water solutes but only 0. 14% of all seawater ions, differences like these are due to the varying residence times of seawater solutes, sodium and chlorine have very long residence times, while calcium tends to precipitate much more quickly. The most abundant dissolved ions in seawater are sodium, chloride, magnesium, sulfate and its osmolarity is about 1000 mOsm/l

Jordan Rift Valley
–
The Jordan Rift Valley, also called the Syro-African Depression, is an elongated depression located in modern-day Israel, Jordan, and Palestine. The Jordan Rift Valley was formed millions of years ago in the Miocene epoch when the Arabian Plate moved northward. One million years later, the land between the Mediterranean and the Jordan Rift Valley rose so that the sea water stopped flooding the area, the outcropping formations around the basins represent alternating deposition and erosion phases. The lowest point in the Jordan Rift Valley is in the Dead Sea, the shore of the Dead Sea is the lowest land on earth, at 400 meters below sea level. Rising sharply to almost 1,000 meters in the west, and similarly in the east, the valley north of the Dead Sea has long been a site of agriculture because of water available from the Jordan River and numerous springs located on the valleys flanks. The plate boundary which extends through the valley is called the Dead Sea Transform or Dead Sea Rift. The boundary separates the Arabian Plate from the African Plate, connecting the divergent plate boundary in the Red Sea to the East Anatolian Fault in Turkey, the DST fault system is generally considered to be a transform fault that has accommodated a 105-km-northwards displacement of the Arabian Plate. GPS data give similar rates of movement of the Arabian Plate relative to the Africa Plate. It has also proposed that the fault zone is a rift system that is an incipient oceanic spreading center.

Tributary
–
A tributary or affluent is a stream or river that flows into a larger stream or main stem river or a lake. A tributary does not flow directly into a sea or ocean, tributaries and the main stem river drain the surrounding drainage basin of its surface water and groundwater, leading the water out into an ocean. A confluence, where two or more bodies of water together, usually refers to the joining of tributaries. The opposite to a tributary is a distributary, a river or stream that branches off from, distributaries are most often found in river deltas. Right tributary and left tributary are terms stating the orientation of the relative to the flow of the main stem river. These terms are defined from the perspective of looking downstream, where tributaries have the same name as the river into which they feed, they are called forks. These are typically designated by compass direction, for example, the American River receives flow from its North, Middle, and South forks. The Chicago Rivers North Branch has the East, West, and Middle Fork, the South Branch has its South Fork, forks are sometimes designated as right or left. Here, the handedness is from the point of view of an observer facing upstream, for instance, Steer Creek has a left tributary which is called Right Fork Steer Creek. Tributaries are sometimes listed starting with those nearest to the source of the river, the Strahler Stream Order examines the arrangement of tributaries in a hierarchy of first, second, third, and higher orders, with the first-order tributary being typically the least in size. For example, a second-order tributary would be the result of two or more first-order tributaries combining to form the second-order tributary, another method is to list tributaries from mouth to source, in the form of a tree structure, stored as a tree data structure

Mediterranean Basin
–
As a rule of thumb, the Mediterranean Basin is the Old World region where olive trees grow. The Mediterranean basin covers portions of three continents Africa, Asia, and Europe and it has a varied and contrasting topography. Contrary to the sandy beach images portrayed in most tourist brochures. Mountains can be seen from almost anywhere, the Mediterranean Basin extends into Western Asia, covering the western and southern portions of the peninsula of Turkey, excluding the temperate-climate mountains of central Turkey. It includes the Mediterranean climate Levant at the end of the Mediterranean, bounded on the east and south by the Syrian. The northern portion of the Maghreb region of northwestern Africa has a Mediterranean climate, separated from the Sahara Desert, Europe lies to the north, and three large Southern European peninsulas, the Iberian Peninsula, Italian Peninsula, and the Balkan Peninsula, extend into the Mediterranean-climate zone. The Mediterranean Basin was shaped by the ancient collision of the northward-moving African-Arabian continent with the stable Eurasian continent, as Africa-Arabia moved north, it closed the former Tethys Sea, which formerly separated Eurasia from the ancient super continent of Gondwana, of which Africa was part. At about the time,170 mya in the Jurassic period. The collision pushed up a vast system of mountains, extending from the Pyrenees in Spain to the Zagros Mountains in Iran and this episode of mountain building, known as the Alpine orogeny, occurred mostly during the Oligocene and Miocene epochs. The Neotethys became larger during these collisions and associated folding and subduction, about 6 mya during the late Miocene, the Mediterranean was closed at its western end by drifting Africa, which caused the entire sea to evaporate. There followed several episodes of sea drawdown and re-flooding known as the Messinian Salinity Crisis, recent studies, however, show that repeated desiccation and re-flooding is unlikely from a geodynamic point of view. The end of the Miocene also marked a change in the Mediterranean Basins climate, fossil evidence shows that the Mediterranean Basin had a relatively humid subtropical climate with summer rainfall during the Miocene, which supported laurel forests. The shift to a Mediterranean climate occurred within the last 3. 2–2.8 million years, during the Pliocene epoch, much of these forests and shrublands have been altered beyond recognition by thousands of years of human habitation. There are now very few relatively intact natural areas in what was once a wooded region. The Mediterranean Region was first proposed by German botanist August Grisebach in the late 19th century, drosophyllaceae, recently segregated from Droseraceae, is the only plant family endemic to the region. Among the endemic plant genera are, The genera Aubrieta, Sesamoides, Cynara, Dracunculus, moreover, many plant taxa are shared with one of the four neighboring floristic regions only. The Mediterranean Basin is the largest of the worlds five Mediterranean forests, woodlands and it is home to a number of plant communities, which vary with rainfall, elevation, latitude, and soils. Scrublands occur in the driest areas, especially areas near the seacoast where wind, low, soft-leaved scrublands around the Mediterranean are known as garrigar in Catalan, garrigue in French, phrygana in Greek, tomillares in Spanish, and batha in Hebrew

Herod the Great
–
Herod, also known as Herod the Great and Herod I, was a Roman client king of Judea, referred to as the Herodian kingdom. Vital details of his life are recorded in the works of the 1st century CE Roman–Jewish historian Josephus, Herod also appears in the Christian Gospel of Matthew as the ruler of Judea who orders the Massacre of the Innocents at the time of the birth of Jesus. Despite his successes, including singlehandedly forging a new aristocracy from practically nothing and his reign polarizes opinion amongst scholars and historians, some viewing his legacy as evidence of success, or a reminder of his tyrannical rule. It is generally accepted that Herod was born around 73 BCE in Idumea, however, some authors think that he was born in about 72/71 BCE. He was the son of Antipater the Idumaean, a high-ranked official under ethnarch Hyrcanus II, and Cypros. Herods father was by descent an Edomite whose ancestors had converted to Judaism, Herod was raised as a Jew. A loyal supporter of Hyrcanus II, Antipater appointed his son governor of Galilee in 47 BCE and his elder brother, Phasael, was appointed governor of Jerusalem. Herod enjoyed the backing of Rome, but his brutality was condemned by the Sanhedrin, in 41 BCE, Herod and his brother Phasael, were named as tetrarchs by the Roman leader Mark Antony. They were placed in this role to support Hyrcanus II, later, Antigonus, Hyrcanus nephew, took the throne from his uncle with the help of the Parthians. Herod fled to Rome to plead with the Romans to restore Hyrcanus II to power, the Romans had a special interest in Judea because their general Pompey the Great had conquered Jerusalem in 63 BCE, thus placing the region in the Roman sphere of influence. In Rome, Herod was unexpectedly appointed King of the Jews by the Roman Senate, Josephus puts this in the year of the consulship of Calvinus and Pollio, but Appian places it in 39 BCE. Herod went back to Judea to win his kingdom from Antigonus, toward the end of the campaign against Antigonus, Herod married the granddaughter of Hyrcanus II, Mariamne, who was also a niece of Antigonus. Herod did this in an attempt to secure his claim to the throne, however, Herod already had a wife, Doris, and a young son, Antipater, and chose therefore to banish Doris and her child. After three years of conflict, Herod and the Romans finally captured Jerusalem and Herod sent Antigonus for execution to Marc Antony, Herod took the role as sole ruler of Judea and the title of basileus for himself, ushering in the Herodian Dynasty and ending the Hasmonean Dynasty. Josephus reports this as being in the year of the consulship of Agrippa and Gallus, but also says that it was exactly 27 years after Jerusalem fell to Pompey, cassius Dio also reports that in 37 BCE the Romans accomplished nothing worthy of note in the area. According to Josephus, Herod ruled for 37 years,34 of them after capturing Jerusalem, as Herods family were converts to Judaism, his religious commitment was questioned by some elements of Jewish society. Herod later executed several members of his own family, including his wife Mariamne I, Herods rule marked a new beginning in the history of Judea. Judea had been ruled autonomously by the Hasmonean kings from 140 BCE until 63 BCE, the Hasmoneans retained their titles, but became clients of Rome after the conquest by Pompey in 63 BCE

Ancient Egypt
–
Ancient Egypt was a civilization of ancient Northeastern Africa, concentrated along the lower reaches of the Nile River in what is now the modern country of Egypt. It is one of six civilizations to arise independently, Egyptian civilization followed prehistoric Egypt and coalesced around 3150 BC with the political unification of Upper and Lower Egypt under the first pharaoh Narmer. In the aftermath of Alexander the Greats death, one of his generals, Ptolemy Soter and this Greek Ptolemaic Kingdom ruled Egypt until 30 BC, when, under Cleopatra, it fell to the Roman Empire and became a Roman province. The success of ancient Egyptian civilization came partly from its ability to adapt to the conditions of the Nile River valley for agriculture, the predictable flooding and controlled irrigation of the fertile valley produced surplus crops, which supported a more dense population, and social development and culture. Its art and architecture were widely copied, and its antiquities carried off to far corners of the world and its monumental ruins have inspired the imaginations of travelers and writers for centuries. The Nile has been the lifeline of its region for much of human history, nomadic modern human hunter-gatherers began living in the Nile valley through the end of the Middle Pleistocene some 120,000 years ago. By the late Paleolithic period, the climate of Northern Africa became increasingly hot and dry. In Predynastic and Early Dynastic times, the Egyptian climate was less arid than it is today. Large regions of Egypt were covered in treed savanna and traversed by herds of grazing ungulates, foliage and fauna were far more prolific in all environs and the Nile region supported large populations of waterfowl. Hunting would have been common for Egyptians, and this is also the period when many animals were first domesticated. The largest of these cultures in upper Egypt was the Badari, which probably originated in the Western Desert, it was known for its high quality ceramics, stone tools. The Badari was followed by the Amratian and Gerzeh cultures, which brought a number of technological improvements, as early as the Naqada I Period, predynastic Egyptians imported obsidian from Ethiopia, used to shape blades and other objects from flakes. In Naqada II times, early evidence exists of contact with the Near East, particularly Canaan, establishing a power center at Hierakonpolis, and later at Abydos, Naqada III leaders expanded their control of Egypt northwards along the Nile. They also traded with Nubia to the south, the oases of the desert to the west. Royal Nubian burials at Qustul produced artifacts bearing the oldest-known examples of Egyptian dynastic symbols, such as the crown of Egypt. They also developed a ceramic glaze known as faience, which was used well into the Roman Period to decorate cups, amulets, and figurines. During the last predynastic phase, the Naqada culture began using written symbols that eventually were developed into a system of hieroglyphs for writing the ancient Egyptian language. The Early Dynastic Period was approximately contemporary to the early Sumerian-Akkadian civilisation of Mesopotamia, the third-century BC Egyptian priest Manetho grouped the long line of pharaohs from Menes to his own time into 30 dynasties, a system still used today

Mummy
–
Some authorities restrict the use of the term to bodies deliberately embalmed with chemicals, but the use of the word to cover accidentally desiccated bodies goes back to at least 1615 CE. Mummies of humans and other animals have found on every continent. Over one million animal mummies have been found in Egypt, many of which are cats, in addition to the well-known mummies of ancient Egypt, deliberate mummification was a feature of several ancient cultures in areas of America and Asia with very dry climates. The Spirit Cave mummies of Fallon, Nevada in North America were accurately dated at more than 9,400 years old. Before this discovery, the oldest known deliberate mummy was a child, one of the Chinchorro mummies found in the Camarones Valley, Chile, which dates around 5050 BCE. The oldest known naturally mummified corpse is a severed head dated as 6,000 years old. These substances were defined as mummia, the OED defines a mummy as the body of a human being or animal embalmed as a preparation for burial, citing sources from 1615 CE onward. However, Chambers Cyclopædia and the Victorian zoologist Francis Trevelyan Buckland define a mummy as follows, also applied to the frozen carcase of an animal imbedded in prehistoric snow. Wasps of the genus Aleiodes are known as mummy wasps because they wrap their prey as mummies. While interest in the study of mummies dates as far back as Ptolemaic Greece, prior to this, many rediscovered mummies were sold as curiosities or for use in pseudoscientific novelties such as mummia. The first modern scientific examinations of mummies began in 1901, conducted by professors at the English-language Government School of Medicine in Cairo, Egypt. The first X-ray of a mummy came in 1903, when professors Grafton Elliot Smith, British chemist Alfred Lucas applied chemical analyses to Egyptian mummies during this same period, which returned many results about the types of substances used in embalming. Lucas also made significant contributions to the analysis of Tutankhamun in 1922, pathological study of mummies saw varying levels of popularity throughout the 20th century. In 1992, the First World Congress on Mummy Studies was held in Puerto de la Cruz on Tenerife in the Canary Islands, more than 300 scientists attended the Congress to share nearly 100 years of collected data on mummies. This was not possible prior to the Congress due to the unique, in more recent years, CT scanning has become an invaluable tool in the study of mummification by allowing researchers to digitally unwrap mummies without risking damage to the body. The level of detail in such scans is so intricate that small linens used in areas such as the nostrils can be digitally reconstructed in 3-D. Such modelling has been utilized to perform autopsies on mummies to determine cause of death and lifestyle. Mummies are typically divided into one of two categories, anthropogenic or spontaneous

Potash
–
Potash /ˈpɒtæʃ/ is any of various mined and manufactured salts that contain potassium in water-soluble form. The name derives from pot ash, which refers to plant ashes soaked in water in a pot, the word potassium is derived from potash. Potash is produced worldwide at amounts exceeding 30 million tonnes per year, various types of fertilizer-potash thus constitute the single largest global industrial use of the element potassium. Potassium was first derived by electrolysis of caustic potash, in 1807, Potash refers to potassium compounds and potassium-bearing materials, the most common being potassium chloride. The term potash comes from the Middle Dutch word potaschen, approximately 10% by weight of common wood ash can be recovered as pot ash. Later, potash became the term applied to naturally occurring potassium salts. Potash ores are rich in potassium chloride and sodium chloride and are typically obtained by conventional shaft mining with the extracted ore ground into a powder. Other methods include dissolution mining and evaporation methods from brines, in the evaporation method hot water is injected into the potash which is dissolved and then pumped to the surface where it is concentrated by solar induced evaporation. Amine reagents are added to either the mined or evaporated solutions. The amine coats the KCl but not NaCl, air bubbles cling to the amine + KCl and float it to the surface while the NaCl and clay sink to the bottom. The surface is skimmed for the amine + KCl which is dried and packaged for use as a K rich fertilizer—KCl dissolves readily in water and is available quickly for plant nutrition. Potash deposits can be all over the world. At present deposits are being mined in Canada, Russia, China, Belarus, Israel, Germany, Chile, the United States, Jordan, Spain, Potash has been used in bleaching textiles, making glass, and making soap, since about AD500. Potash was principally obtained by leaching the ashes of land and sea plants, beginning in the 14th century potash was mined in Ethiopia. One of the worlds largest deposits,140 to 150 million tons, is located in the Tigrays Dallol area, Potash was one of the most important industrial chemicals in Canada. It was refined from the ashes of broadleaved trees and produced primarily in the areas of Europe, Russia. The first U. S. patent of any kind was issued in 1790 to Samuel Hopkins for an improvement in the making of Pot ash and Pearl ash by a new Apparatus, Pearl ash was a purer quality made by the ignition of cream of tartar. Potash pits were used in England to produce potash that was used in making soap for the preparation of wool for yarn production

Fertilizer
–
A fertilizer or fertiliser is any material of natural or synthetic origin that is applied to soils or to plant tissues to supply one or more plant nutrients essential to the growth of plants. Fertilizers enhance the growth of plants and this goal is met in two ways, the traditional one being additives that provide nutrients. The second mode by which some fertilizers act is to enhance the effectiveness of the soil by modifying its water retention and aeration and this article, like many on fertilizers, emphasises the nutritional aspect. The nutrients required for plant life are classified according to the elements. Instead compounds containing these elements are the basis of fertilizers, the macronutrients are consumed in larger quantities and are present in plant tissue in quantities from 0. 15% to 6. 0% on a dry matter basis. Plants are made up of four elements, hydrogen, oxygen, carbon. Carbon, hydrogen and oxygen are widely available as water and carbon dioxide, although nitrogen makes up most of the atmosphere, it is in a form that is unavailable to plants. Nitrogen is the most important fertilizer since nitrogen is present in proteins, DNA, to be nutritious to plants, nitrogen must be made available in a fixed form. Only some bacteria and their host plants can fix atmospheric nitrogen by converting it to ammonia, phosphate is required for the production of DNA and ATP, the main energy carrier in cells, as well as certain lipids. Micronutrients are consumed in quantities and are present in plant tissue on the order of parts-per-million, ranging from 0.15 to 400 ppm DM. These elements are present at the active sites of enzymes that carry out the plants metabolism. Because these elements enable catalysts their impact far exceeds their weight percentage, Fertilizers are classified in several ways. They are classified according to whether they provide a single nutrient, multinutrient fertilizers provide two or more nutrients, for example N and P. Fertilizers are also sometimes classified as inorganic versus organic. Inorganic fertilizers exclude carbon-containing materials except ureas, organic fertilizers are usually plant- or animal-derived matter. Inorganic are sometimes called synthetic fertilizers since various chemical treatments are required for their manufacture, the main nitrogen-based straight fertilizer is ammonia or its solutions. Ammonium nitrate is widely used. Urea is another source of nitrogen, having the advantage that it is solid and non-explosive, unlike ammonia and ammonium nitrate. A few percent of the fertilizer market has been met by calcium ammonium nitrate

Cosmetics
–
Cosmetics, also known as make-up, are substances or products used to enhance or alter the appearance or fragrance of the body. Many cosmetics are designed for use of applying to the face and they are generally mixtures of chemical compounds, some being derived from natural sources, and some being synthetics. Common cosmetics include lipstick, mascara, eye shadow, foundation, rouge, skin cleansers and skin lotions, shampoo, hairstyling products, perfume and this broad definition includes any material intended for use as a component of a cosmetic product. The FDA specifically excludes soap from this category, Egyptian women and men also used makeup. They were very fond of eyeliner and eyeshadows in dark colors including blue, red, Ancient Sumerian men and women were possibly the first to invent and wear lipstick, about 5,000 years ago. They crushed gemstones and used them to decorate their faces, mainly on the lips, also around 3000 BC to 1500 BC, women in the ancient Indus Valley Civilization applied red tinted lipstick to their lips for face decoration. Ancient Egyptians extracted red dye from fucus-algin,0. 01% iodine, and some bromine mannite, lipsticks with shimmering effects were initially made using a pearlescent substance found in fish scales. Six thousand year old relics of the hollowed out tombs of the Ancient Egyptian pharaohs are discovered, according to one source, early major developments include, Kohl used by ancient Egypt as a protective of the eye kohl Castor oil used by ancient Egypt as a protective balm. Skin creams made of beeswax, olive oil, and rose water, vaseline and lanolin in the nineteenth century. The Ancient Greeks also used cosmetics as the Ancient Romans did, Cosmetics are mentioned in the Old Testament, such as in 2 Kings 9,30, where Jezebel painted her eyelids—approximately 840 BC—and in the book of Esther, where beauty treatments are described. One of the most popular traditional Chinese medicines is the fungus Tremella fuciformis, used as a beauty product by women in China, the fungus reportedly increases moisture retention in the skin and prevents senile degradation of micro-blood vessels in the skin, reducing wrinkles and smoothing fine lines. Cosmetic use was frowned upon at many points in Western history, for example, in the 19th century, Queen Victoria publicly declared make-up improper, vulgar, and acceptable only for use by actors. During the sixteenth century, the attributes of the women who used make-up created a demand for the product among the upper class. As of 2016, the worlds largest cosmetics company is LOréal, the market was developed in the US during the 1910s by Elizabeth Arden, Helena Rubinstein, and Max Factor. These firms were joined by Revlon just before World War II, during the 18th century, there was a high number of incidences of lead-poisoning because of the fashion for red and white lead makeup and powder. This led to swelling and inflammation of the eyes, attacked tooth enamel, heavy use was known to lead to death. Concealer is commonly used by men, Cosmetics brands release products especially tailored for men, and men are increasingly using them. Cosmetics are intended to be applied externally, a subset of cosmetics is called make-up, refers primarily to products containing color pigments that are intended to alter the users appearance

Sachet
–
A sachet /ˈsæʃeɪ/ is a small cloth scented bag filled with herbs, potpourri, or aromatic ingredients. In the Han Dynasty both boys and girls wore sachets and in the Tang Dynasty and Song Dynasty scented bags gradually became preferred only by women. During the Chinese Warring States period a scented sachet was an ornament worn on the body and used to sweat, repel insects. A scented sachet became a token in the Qing Dynasty. Queen Isabella of Spain used fragrant sachets consisting of dried rose and carnation petals, orris and calamus root, in the nineteenth century a sachet filled with hops was called a Pulvinar Humuli and used by George III of Great Britain and Prince Albert of Saxe-Coburg to help induce sleep. In medieval times it was known as a plague-bag and these were generally worn around the neck, or dangled from the waist. It was believed that provided protection against parasites and miasmata. These sachets contained sweet powders, aromatic calamus, benzoin, storax, galingale, cloves, in modern times it is a small cloth bag filled with potpourri that is laid among garments in a dresser. Scented sachets are for containing odorous substances to be laid among handkerchiefs to perfume them and they are also used to make undergarments and outer garments sweet smelling as well as placed amongst linens. Scented sachets are also hung in closets and cupboards and they are also put into briefcases and luggage. Some are used in stationary packets and others are put under pillows to help one sleep, scented sachets are sweet bags and are put in automobiles, clothes dryers, clothes closets, inside or about childrens stuffed animals, on the backs of chairs, and on doorknobs. Sachets with herbs like hops and lavender act as a sedative and these type of sachets are often put in closets and dresser drawers for their scents. Some dream pillow types of scented sachets are made with sleep inducing ingredients like hops, chamomile, valerian, skullcap and these scented sachets of aromatic herbs are also referred to as herb pillows or sleep pillows and are designed to overcome sleeplessness. These herb filled sachets are even called dreamtime pillows, there are formulas using rosemary seeds to fill sachets and these are to be hung in a bedroom to promote sleep. The traditional method to treat insomnia with herb filled sachets of hops or lavender is to them in. The dream pillow or sleep pillow sachet concept has been used for decades to overcome sleeplessness. These sleep pillows have an effect and hops as an ingredient to this type of sachet are considered best at inducing sleep. One type of sleep pillow sachet recipe by herb and flower author Penny Black calls for violets, rose petals, rosemary, tonka bean, vanilla bean, scented sachets are many times homemade and come in many sizes, styles, shapes and fragrances

Density
–
The density, or more precisely, the volumetric mass density, of a substance is its mass per unit volume. The symbol most often used for density is ρ, although the Latin letter D can also be used. Mathematically, density is defined as mass divided by volume, ρ = m V, where ρ is the density, m is the mass, and V is the volume. In some cases, density is defined as its weight per unit volume. For a pure substance the density has the numerical value as its mass concentration. Different materials usually have different densities, and density may be relevant to buoyancy, purity, osmium and iridium are the densest known elements at standard conditions for temperature and pressure but certain chemical compounds may be denser. Thus a relative density less than one means that the floats in water. The density of a material varies with temperature and pressure and this variation is typically small for solids and liquids but much greater for gases. Increasing the pressure on an object decreases the volume of the object, increasing the temperature of a substance decreases its density by increasing its volume. In most materials, heating the bottom of a results in convection of the heat from the bottom to the top. This causes it to rise relative to more dense unheated material, the reciprocal of the density of a substance is occasionally called its specific volume, a term sometimes used in thermodynamics. Density is a property in that increasing the amount of a substance does not increase its density. Archimedes knew that the irregularly shaped wreath could be crushed into a cube whose volume could be calculated easily and compared with the mass, upon this discovery, he leapt from his bath and ran naked through the streets shouting, Eureka. As a result, the term eureka entered common parlance and is used today to indicate a moment of enlightenment, the story first appeared in written form in Vitruvius books of architecture, two centuries after it supposedly took place. Some scholars have doubted the accuracy of this tale, saying among other things that the method would have required precise measurements that would have been difficult to make at the time, from the equation for density, mass density has units of mass divided by volume. As there are units of mass and volume covering many different magnitudes there are a large number of units for mass density in use. The SI unit of kilogram per metre and the cgs unit of gram per cubic centimetre are probably the most commonly used units for density.1,000 kg/m3 equals 1 g/cm3. In industry, other larger or smaller units of mass and or volume are often more practical, see below for a list of some of the most common units of density

Buoyancy
–
In science, buoyancy or upthrust, is an upward force exerted by a fluid that opposes the weight of an immersed object. In a column of fluid, pressure increases with depth as a result of the weight of the overlying fluid, thus the pressure at the bottom of a column of fluid is greater than at the top of the column. Similarly, the pressure at the bottom of an object submerged in a fluid is greater than at the top of the object and this pressure difference results in a net upwards force on the object. For this reason, an object whose density is greater than that of the fluid in which it is submerged tends to sink, If the object is either less dense than the liquid or is shaped appropriately, the force can keep the object afloat. This can occur only in a reference frame, which either has a gravitational field or is accelerating due to a force other than gravity defining a downward direction. In a situation of fluid statics, the net upward force is equal to the magnitude of the weight of fluid displaced by the body. The center of buoyancy of an object is the centroid of the volume of fluid. Archimedes principle is named after Archimedes of Syracuse, who first discovered this law in 212 B. C, more tersely, Buoyancy = weight of displaced fluid. The weight of the fluid is directly proportional to the volume of the displaced fluid. Thus, among completely submerged objects with equal masses, objects with greater volume have greater buoyancy and this is also known as upthrust. Suppose a rocks weight is measured as 10 newtons when suspended by a string in a vacuum with gravity acting upon it, suppose that when the rock is lowered into water, it displaces water of weight 3 newtons. The force it exerts on the string from which it hangs would be 10 newtons minus the 3 newtons of buoyancy force,10 −3 =7 newtons. Buoyancy reduces the apparent weight of objects that have sunk completely to the sea floor and it is generally easier to lift an object up through the water than it is to pull it out of the water. The density of the object relative to the density of the fluid can easily be calculated without measuring any volumes. Density of object density of fluid = weight weight − apparent immersed weight Example, If you drop wood into water, Example, A helium balloon in a moving car. During a period of increasing speed, the air mass inside the car moves in the direction opposite to the cars acceleration, the balloon is also pulled this way. However, because the balloon is buoyant relative to the air, it ends up being pushed out of the way, If the car slows down, the same balloon will begin to drift backward. For the same reason, as the car goes round a curve and this is the equation to calculate the pressure inside a fluid in equilibrium

Salt
–
Salt is present in vast quantities in seawater, where it is the main mineral constituent. The open ocean has about 35 grams of solids per litre, Salt is essential for life in general, and saltiness is one of the basic human tastes. The tissues of animals contain larger quantities of salt than do plant tissues, Salt is one of the oldest and most ubiquitous food seasonings, and salting is an important method of food preservation. Salt was also prized by the ancient Hebrews, the Greeks, the Romans, the Byzantines, the Hittites, Egyptians, and the Indians. Salt became an important article of trade and was transported by boat across the Mediterranean Sea, along specially built salt roads, the scarcity and universal need for salt has led nations to go to war over it and use it to raise tax revenues. Salt is used in ceremonies and has other cultural significance. Salt is processed from salt mines, or by the evaporation of seawater or mineral-rich spring water in shallow pools. Its major industrial products are caustic soda and chlorine, and is used in industrial processes including the manufacture of polyvinyl chloride, plastics, paper pulp. Of the annual production of around two hundred million tonnes of salt, only about 6% is used for human consumption. Other uses include water conditioning processes, de-icing highways, and agricultural use, edible salt is sold in forms such as sea salt and table salt which usually contains an anti-caking agent and may be iodised to prevent iodine deficiency. As well as its use in cooking and at the table, sodium is an essential nutrient for human health via its role as an electrolyte and osmotic solute. Excessive salt consumption can increase the risk of diseases, such as hypertension, in children. Such health effects of salt have long been studied, accordingly, numerous world health associations and experts in developed countries recommend reducing consumption of popular salty foods. The World Health Organization recommends that adults should consume less than 2,000 mg of sodium, humans have always tended to build communities either around sources of salt, or where they can trade for it. All through history the availability of salt has been pivotal to civilization, the word salary comes from the Latin word for salt because the Roman Legions were sometimes paid in salt. The Natron Valley was a key region that supported the Egyptian Empire to its north, because it supplied it with a kind of salt that came to be called by its name, natron. Even before this, what is now thought to have been the first city in Europe is Solnitsata, in Bulgaria, even the name Solnisata means salt works. A very ancient salt-works operation has been discovered at the Poiana Slatinei archaeological site next to a spring in Lunca, Neamț County

Book of Genesis
–
The Book of Genesis is the first book of the Hebrew Bible and the Christian Old Testament. The basic narrative expresses the theme, God creates the world and appoints man as his regent. The new post-Flood world is also corrupt, God does not destroy it, instead calling one man, Abraham, to be the seed of its salvation. At Gods command Abraham descends from his home into the land of Canaan, given to him by God, Genesis ends with Israel in Egypt, ready for the coming of Moses and the Exodus. The narrative is punctuated by a series of covenants with God, the books author or authors appear to have structured it around ten toledot sections, but modern commentators see it in terms of a primeval history followed by the cycle of Patriarchal stories. In Judaism, the importance of Genesis centers on the covenants linking God to his chosen people. It is not clear, however, what this meant to the original authors, while the first is far shorter than the second, it sets out the basic themes and provides an interpretive key for understanding the entire book. The primeval history has a symmetrical structure hinging on chapters 6–9, God creates the world in six days and consecrates the seventh as a day of rest. God creates the first humans Adam and Eve and all the animals in the Garden of Eden but instructs them not to eat the fruit of the tree of knowledge of good and evil. A talking serpent portrayed as a creature or trickster, entices Eve into eating it anyway. Eve bears two sons, Cain and Abel, Cain kills Abel after God accepts Abels offering but not Cains. Eve bears another son, Seth, to take Abels place, after many generations of Adam have passed from the lines of Cain and Seth, the world becomes corrupted by the sin of man and Nephilim, and God determines to wipe out mankind. First, he instructs the righteous Noah and his family to build a huge boat, then God sends a great flood to wipe out the rest of the world. When the waters recede, God promises that he not destroy the world a second time with water with the rainbow as the symbol of his promise. But upon seeing mankind cooperating to build a great tower city, God instructs Abram to travel from his home in Mesopotamia to the land of Canaan. Abrams name is changed to Abraham and that of his wife Sarai to Sarah, because Sarah is old, she tells Abraham to take her Egyptian handmaiden, Hagar, as a second wife. God resolves to destroy the cities of Sodom and Gomorrah for the sins of their people, Abraham protests and gets God to agree not to destroy the cities if 10 righteous men can be found. Angels save Abrahams nephew Lot and his family, but his wife back on the destruction against their command and is turned into a pillar of salt

Lot (biblical person)
–
Lot was a patriarch in the biblical Book of Genesis chapters 11–14 and 19. Lot and his father Haran were born and raised in Ur of the Chaldees in the region of Sumeria on the Euphrates River of lower Mesopotamia, Haran died in that land before his father Terah. Genesis 11, 26-32 gives the generations of Terah, Lots grandfather, among the family members that Lot travelled with was his uncle Abram, one of the three patriarchs of Israel. En route to Canaan, the family stopped in the Paddan Aram region and they settled at the site called Haran where Lots grandfather, Terah, lived the rest of his days. He was 205 years old when he died, Genesis 12 reveals Abrams obedience to the LORD at the age of 75, in continuing his journey to the land of promise. Though Abrams father, Terah, stayed behind, his nephew Lot went with him, there is no mention of Lot having a wife yet. They went southwestward into the land of Canaan, to the place of Sichem, later they travelled south to the hills between Bethel and Hai, before journeying further toward the south of Canaan. After dwelling in the land of Canaan for a little while, there was a famine, after having dwelt in Egypt for some time, they acquired vast amounts of wealth and livestock, and returned to the Bethel area. Genesis 13 helps and discusses Abram and Lots return to Canaan after the famine had passed and they traveled back through the Negev to the hills of Bethel. With their sizeable numbers of livestock and always on the move, the conflicts between herdsmen had become so troublesome that Abram recommended to Lot that they should part ways, lest there be conflict amongst brethren. Abram then headed south to Hebron, staying within the land of Canaan, Lot had encamped on the green Jordan plain among the cities of the plain and initially pitched his tent toward Sodom. The following year the four armies with Chedorlaomer returned and at the Battle of the Vale of Siddim, Chedorlaomer spoiled the cities and took captives as he departed, including Lot, who by then dwelt in Sodom. He divided his forces and attacked at night more than one direction. The pursuit continued and the slaughter of Chedorlaomer, and the kings was completed at Hobah north of Damascus. Abram brought back his brother Lot and all the people and their goods, twenty four years after Abram and Lot began their sojourning, the LORD changed Abrams name to Abraham, and gave him the covenant of circumcision. Not long afterward, the LORD appeared to Abraham, for three men came to visit and have a meal with him, and after two left to go to Sodom, Abraham stood yet before the LORD. Abraham boldly pleaded on behalf of the people of Sodom, where Lot dwelt and he continued inquiring, reducing the number to forty five, forty, thirty, twenty, and finally if there were ten righteous in the city, it would be spared. After supper that night before bedtime, the men of the city, young and old and his response infuriated the men of Sodom who accused him of being judgmental and they threatened to do worse to him than they would have done to the men

Attic Greek
–
Attic Greek is the Greek dialect of ancient Attica, including of the city of Athens. Of the ancient dialects, it is the most similar to later Greek and is the form of the language that is studied in ancient Greek language courses. Attic Greek is sometimes included in the Ionic dialect, together, Attic and Ionic are the primary influences on Modern Greek. Greek is the member of the Hellenic branch of the Indo-European language family. In ancient times, Greek had already come to exist in several dialects, mycenaean Greek represents an early form of Eastern Greek, the group to which Attic also belongs. Later Greek literature wrote about three main dialects, Aeolic, Doric, and Ionic, Attic was part of the Ionic dialect group, ruling from Alexandria, Ptolemy launched the Alexandrian period, during which the city of Alexandria and its expatriate Greek-medium scholars flourished. The earliest Greek literature, which is attributed to Homer and is dated to the 8th or 7th centuries BC, is written in Old Ionic rather than Attic. The first extensive works of literature in Attic are the plays of the dramatists Aeschylus, the military exploits of the Athenians led to some universally read and admired history, as found in the works of Thucydides and Xenophon. Slightly less known because they are technical and legal are the orations by Antiphon, Demosthenes, Lysias, Isocrates. The Attic Greek of the philosophers Plato and his student Aristotle dates to the period of transition between Classical Attic and Koine, Attic Greek, like other dialects, was originally written in a local variant of the Greek alphabet. In other respects, Old Attic shares many features with the neighbouring Euboean alphabet, like the latter, it used an L-shaped variant of lambda and an S-shaped variant of sigma. It lacked the consonant symbols xi for /ks/ and psi for /ps/, expressing these sound combinations with ΧΣ, moreover, like most other mainland Greek dialects, Attic did not yet use omega and eta for the long vowels /ɔ, / and /ɛ, /. Instead, it expressed the vowel phonemes /o, oː, ɔː/ with the letter Ο and /e, eː, moreover, the letter Η was used as heta, with the consonantal value of /h/ rather than the vocalic value of /ɛː/. In the 5th century, Athenian writing gradually switched from this system to the more widely used Ionic alphabet, native to the eastern Aegean islands. This new system, also called the Eucleidian alphabet, after the name of the archon Eucleides, the classical works of Attic literature were subsequently handed down to posterity in the new Ionic spelling, and it is the classical orthography in which they are read today. Proto-Greek long ā → Attic long ē, but ā after e, i, r, ⁓ Ionic ē in all positions. ⁓ Doric and Aeolic ā in all positions, Proto-Greek and Doric mātēr → Attic mētēr mother Attic chōrā ⁓ Ionic chōrē place, country However, Proto-Greek ā → Attic ē after w, deleted by the Classical Period.

Satellite imagery
–
Satellite imagery consists of images of Earth or other planets collected by satellites. Imaging satellites are operated by governments and businesses around the world, Satellite imaging companies sell images under licence. Images are licensed to governments and businesses such as Apple Maps, the first images from space were taken on sub-orbital flights. The U. S-launched V-2 flight on October 24,1946 took one image every 1.5 seconds. With an apogee of 65 miles, these photos were from five times higher than the previous record, the first satellite photographs of Earth were made on August 14,1959 by the U. S. The first satellite photographs of the Moon might have made on October 6,1959 by the Soviet satellite Luna 3. The Blue Marble photograph was taken from space in 1972, and has very popular in the media. Also in 1972 the United States started the Landsat program, the largest program for acquisition of imagery of Earth from space, Landsat Data Continuity Mission, the most recent Landsat satellite, was launched on 11 February 2013. In 1977, the first real time satellite imagery was acquired by the United Statess KH-11 satellite system, all satellite images produced by NASA are published by NASA Earth Observatory and are freely available to the public. Several other countries have satellite imaging programs, and a collaborative European effort launched the ERS, there are also private companies that provide commercial satellite imagery. Images can be in visible colours and in other spectra, there are also elevation maps, usually made by radar images. Interpretation and analysis of imagery is conducted using specialized remote sensing applications. There are four types of resolution when discussing satellite imagery in remote sensing, spatial, spectral, temporal, and radiometric. GSD is a term containing the optical and systemic noise sources and is useful for comparing how well one sensor can see an object on the ground within a single pixel. For example, the GSD of Landsat is ~30m, which means the smallest unit that maps to a single pixel within an image is ~30m x 30m, the latest commercial satellite has a GSD of 0.41 m. This compares to a 0.3 m resolution obtained by some early military film based Reconnaissance satellite such as Corona, the resolution of satellite images varies depending on the instrument used and the altitude of the satellites orbit. For example, the Landsat archive offers repeated imagery at 30 meter resolution for the planet, Landsat 7 has an average return period of 16 days. For many smaller areas, images with resolution as high as 41 cm can be available, Satellite imagery is sometimes supplemented with aerial photography, which has higher resolution, but is more expensive per square meter

Dead Sea Transform
–
The Dead Sea Transform fault system, also sometimes referred to as the Dead Sea Rift, is a series of faults that run from the Maras Triple Junction to the northern end of the Red Sea Rift. The fault system forms the boundary between the African Plate to the west and the Arabian Plate to the east. It is a zone of left lateral displacement, signifying the relative motions of the two plates, both plates are moving in a general north-northeast direction, but the Arabian Plate is moving faster, resulting in the observed left lateral motions along the fault of approximately 107 km. The DST fault system is considered to be a transform fault that has accommodated a 105 km northwards displacement of the Arabian Plate. GPS data give similar rates of movement of the Arabian Plate relative to the Africa Plate. It has also proposed that the fault zone is a rift system that is an incipient oceanic spreading center. The Dead Sea Transform began to form during the early to mid-Miocene, a total displacement of 64 km has been estimated for this early phase of motion. In the Pliocene the DST propagated northwards once more through Lebanon into northwestern Syria before reaching the East Anatolian Fault. The southern section of the DST is about 400 km long, extending from the center in the Red Sea at southern end of the Gulf of Aqaba to just north of the Hula basin in southernmost Lebanon. The Gulf of Aqaba was created by movement on four left-stepping strike-slip fault segments in a diagonal stepwise sequence known as echelon formation. In the areas where these segments overlap, pull-apart basins have developed, parts of three of these faults ruptured during the 1995 Gulf of Aqaba earthquake. The Wadi Arabah segment of the DST extends for about 160 km from the Gulf of Aqaba to the end of the Dead Sea. Some researchers have further broken down this segment, recognising two separate segments, Avrona and Arava, the Avrona fault extends from the northern part of the Gulf of Aqaba for about 50 km along the Arava Valley. The Arava fault runs from just north of the Avrona fault segment for about 100 km, a slip rate of 4 ±2 mm per year has been estimated from the offset of gullies across the fault. Four major earthquakes are thought to have occurred due to movement on this fault in the last 1,000 years, the Dead Sea is formed in a pull-apart basin due to the left-stepping offset between the Wadi Arabah and Jordan Valley segments. The part of the basin with a fill of more than 2 km is 150 km long. In the north, the fill reaches its maximum thickness of about 10 km. The Jordan valley segment of the DST, the Jordan Rift Valley, a slip rate of between 4.7 and 5.1 mm per year has been estimated over the last 47,500 years

Transform fault
–
A transform fault or transform boundary, is a type of fault whose relative motion is predominantly horizontal, in either a sinistral or dextral direction. Furthermore, transform faults end abruptly and are connected on both ends to other faults, ridges, or subduction zones, Transform faults are the only type of strike-slip fault that can be classified as a plate boundary. The new class of faults, called transform faults, produce slip in the direction from what one would surmise from the standard interpretation of an offset geological feature. Slip along transform faults does not increase the distance between the ridges it separates, the distance remains constant in earthquakes because the ridges are spreading centers. This hypothesis was confirmed in a study of the fault plane solutions that showed the slip on transform faults points in the opposite direction than classical interpretation would suggest, Transform faults are closely related to transcurrent faults, and are commonly confused. In addition, transform faults have equal deformation across the fault line, while transcurrent faults have greater displacement in the middle of the fault zone. Finally, transform faults can form a plate boundary, while transcurrent faults cannot. The effect of a fault is to strain, which can be caused by compression, extension. Transform faults specifically relieve strain by transporting the strain between ridges or subduction zones, Transform faults also act as the plane of weakness allowing for the splitting in rift zones. Transform faults are commonly found linking segments of mid-oceanic ridges or spreading centres and these mid-oceanic ridges are where new seafloor is constantly created through the upwelling of new basaltic magma. With new seafloor being pushed and pulled out, the older seafloor slowly slides away from the mid-oceanic ridges toward the continents, although separated only by tens of kilometers, this separation between segments of the ridges causes portions of the seafloor to push past each other in opposing directions. This lateral movement of seafloors past each other is where transform faults are currently active, Transform faults move differently than a strike-slip fault at the mid-oceanic ridge. Evidence of this can be found in paleomagnetic striping on the seafloor, a paper written by Gerya theorizes that the creation of the transform faults between the ridges of the mid-oceanic ridge is attributed to rotated and stretched sections of the mid-oceanic ridge. This occurs over a period of time with the spreading center or ridge slowly deforming from a straight line to a curved line. Finally, fracturing along these planes forms transform faults, as this takes place, the fault changes from a normal fault with extensional stress to a strike slip fault with lateral stress. In the study done by Bonatti & Crane, peridotite and gabbro rocks were discovered in the edges of the transform ridges and these rocks are created deep inside the Earth’s mantle and then rapidly exhumed to the surface. This evidence helps to prove that new seafloor is being created at the mid-oceanic ridges, as previously stated, active transform faults are between two tectonic structures or faults. Fracture zones represent the active transform fault lines, which have since passed the active transform zone and are being pushed toward the continents

Plate tectonics
–
The theoretical model builds on the concept of continental drift developed during the first few decades of the 20th century. The geoscientific community accepted plate-tectonic theory after seafloor spreading was validated in the late 1950s, the lithosphere, which is the rigid outermost shell of a planet, is broken up into tectonic plates. The Earths lithosphere is composed of seven or eight major plates, where the plates meet, their relative motion determines the type of boundary, convergent, divergent, or transform. Earthquakes, volcanic activity, mountain-building, and oceanic trench formation occur along plate boundaries. The relative movement of the plates typically ranges from zero to 100 mm annually, tectonic plates are composed of oceanic lithosphere and thicker continental lithosphere, each topped by its own kind of crust. Along convergent boundaries, subduction carries plates into the mantle, the material lost is balanced by the formation of new crust along divergent margins by seafloor spreading. In this way, the surface of the lithosphere remains the same. This prediction of plate tectonics is also referred to as the conveyor belt principle, earlier theories, since disproven, proposed gradual shrinking or gradual expansion of the globe. Tectonic plates are able to move because the Earths lithosphere has greater strength than the underlying asthenosphere. Lateral density variations in the result in convection. Plate movement is thought to be driven by a combination of the motion of the seafloor away from the ridge and drag, with downward suction. Another explanation lies in the different forces generated by forces of the Sun. The relative importance of each of these factors and their relationship to other is unclear. The outer layers of the Earth are divided into the lithosphere and asthenosphere and this is based on differences in mechanical properties and in the method for the transfer of heat. Mechanically, the lithosphere is cooler and more rigid, while the asthenosphere is hotter, in terms of heat transfer, the lithosphere loses heat by conduction, whereas the asthenosphere also transfers heat by convection and has a nearly adiabatic temperature gradient. The key principle of plate tectonics is that the lithosphere exists as separate and distinct tectonic plates, Plate motions range up to a typical 10–40 mm/year, to about 160 mm/year. The driving mechanism behind this movement is described below, tectonic lithosphere plates consist of lithospheric mantle overlain by either or both of two types of crustal material, oceanic crust and continental crust. Average oceanic lithosphere is typically 100 km thick, its thickness is a function of its age, as passes, it conductively cools

African Plate
–
The African Plate is a major tectonic plate straddling the equator as well as the prime meridian. It includes much of the continent of Africa, as well as oceanic crust which lies between the continent and various surrounding ocean ridges, between 60 million years ago and 10 million years ago, the Somali Plate began rifting from the African Plate along the East African Rift. All of these are divergent or spreading boundaries with the exception of the northern boundary, the cratons are, from south to north, the Kalahari craton, Congo craton, Tanzania craton and West African craton. The cratons were widely separated in the past, but came together during the Pan-African orogeny, the cratons are connected by orogenic belts, regions of highly deformed rock where the tectonic plates have engaged. The African Plate is rifting in the interior of the African continent along the East African Rift. This rift zone separates the African Plate to the west from the Somali Plate to the east, the African Plates speed is estimated at around 2.15 cm per year. It has been moving over the past 100 million years or so in a general northeast direction and this is drawing it closer to the Eurasian Plate, causing subduction where oceanic crust is converging with continental crust. Along its northeast margin, the African Plate is bounded by the Red Sea Rift where the Arabian Plate is moving away from the African Plate. The New England hotspot in the Atlantic Ocean has probably created a line of mid- to late-Tertiary age seamounts on the African Plate. USGS - Understanding plate motions Meijer, P. Th, wortel, M. J.

Arabian Plate
–
The Arabian Plate is a minor tectonic plate in the northern and eastern hemispheres. It is one of three continental plates that have been moving northward in recent geological history and colliding with the Eurasian Plate, the Arabian Plate consists mostly of the Arabian peninsula, it extends eastward at the Sinai and the Red Sea and northward to the Levant. The Arabian Plate was part of the African plate during much of the Phanerozoic Eon, the opening of the Red Sea rift led to extensive volcanic activity. There are large volcanic fields called the Older Harrats, such as Harrat Khaybar and Harrat Rahat, some activity still continues especially around Medina, and there are regular eruptions within the Red Sea. The collision between the Arabian Plate and Eurasia is pushing up the Zagros Mountains of Iran, because the Arabian Plate and Eurasian Plate collide, many cities are in danger such as those in southeastern Turkey. These dangers include earthquakes, tsunamis, and volcanoes, countries within the plate include Lebanon, Syria, Djibouti, Yemen, Oman, Qatar, Bahrain, Kuwait, Iraq, Saudi Arabia, Jordan, and the United Arab Emirates. Regions include parts of the Southern Denkalya Subregion, the Southeastern Anatolia Region, Awdal and the Khuzestan Province

East Anatolian Fault
–
The East Anatolian Fault is a major strike-slip fault zone in eastern Turkey. It forms the transform type tectonic boundary between the Anatolian Plate and the northward-moving Arabian Plate, the difference in the relative motions of the two plates is manifest in the left lateral motion along the fault. The East and North Anatolian faults together accommodate the motion of the Anatolian Plate as it is squeezed out by the ongoing collision with the Eurasian Plate. From 1939 to 1999 a series of earthquakes progressed westwards along the North Anatolian Fault, but since 2003 there have been a series on the East Anatolian Fault. These started with the 2003 Bingöl earthquake and include the 2010 Elâzığ earthquake, MAY1,2003 BİNGÖL EARTHQUAKE Preliminary Report

Turkey
–
Turkey, officially the Republic of Turkey, is a transcontinental country in Eurasia, mainly in Anatolia in Western Asia, with a smaller portion on the Balkan peninsula in Southeast Europe. Turkey is a democratic, secular, unitary, parliamentary republic with a cultural heritage. The country is encircled by seas on three sides, the Aegean Sea is to the west, the Black Sea to the north, and the Mediterranean Sea to the south. The Bosphorus, the Sea of Marmara, and the Dardanelles, Ankara is the capital while Istanbul is the countrys largest city and main cultural and commercial centre. Approximately 70-80% of the countrys citizens identify themselves as ethnic Turks, other ethnic groups include legally recognised and unrecognised minorities. Kurds are the largest ethnic minority group, making up approximately 20% of the population, the area of Turkey has been inhabited since the Paleolithic by various ancient Anatolian civilisations, as well as Assyrians, Greeks, Thracians, Phrygians, Urartians and Armenians.
