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

Depression (geology)
–
A depression in geology is a landform sunken or depressed below the surrounding area. Erosion-related, Blowout, a depression created by wind erosion typically in either a partially vegetated sand dune ecosystem or dry soils, glacial valley, a depression carved by erosion by a glacier. River valley, a depression carved by erosion by a river. Area of subsidence caused by the collapse of a structure such as sinkholes in karst terrain. Sink, an endorheic depression generally containing a persistent or intermittent lake, collapse-related, Sinkhole, a depression formed as a result of the collapse of rocks lying above a hollow. This is common in karst regions, kettle, a shallow, sediment-filled body of water formed by melting glacial remnants in terminal moraines. Thermokarst hollow, caused by loss of the ground as the result of permafrost thawing. Impact-related, Impact crater, a depression created by an impact such as a meteorite crater, sedimentary-related, Sedimentary basin, in sedimentology, an area thickly filled with sediment in which the weight of the sediment further depresses the floor of the basin. Structural or tectonic-related, Structural basin, a depression, a region of tectonic downwarping as a result of isostasy or subduction. Graben or rift valley, fallen and typically linear depressions or basins created by rifting in a region under tensional tectonic forces, pull-apart basin caused by offset in a strike slip or transform fault. Oceanic trench, a linear depression on the ocean floor. Oceanic trenches are caused by subduction of oceanic crust beneath either oceanic crust or continental crust, pit crater, a volcanic depression smaller than a caldera formed by a sinking, or caving in, of the ground surface lying over a void.

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

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

Hula Valley
–
The Hula Valley is an agricultural region in northern Israel with abundant fresh water. It is a stopover for birds migrating along the Syrian-African Rift Valley between Africa, Europe, and Asia. The marshland around Lake Hula, a ground for mosquitoes carrying malaria, was drained in the 1950s. A small section of the valley was later reflooded in an attempt to revive a nearly extinct ecosystem, an estimated 500 million migrating birds now pass through the Hula Valley every year. Lake Hula was historically referred to by different names, the 14th century BCE Egyptians called the lake Samchuna, while the Hebrew Bible records it as Merom. In the 1st century CE, the Jewish-Roman historian Flavius Josephus termed it Semechonitis, John Lightfoot writing it as Samochonitis, currently the lake is called Buheirat el Huleh in Arabic and Agam ha-Hula in Hebrew, stemming from the Aramaic Hulata or Ulata. The Waters of Merom has sometimes used in scientific literature. On both sides of the valley are steep slopes, the Golan Heights to the east and the Upper Galilees Naftali mountains to the west rise to 400 to 900 meters above sea level. Annual rainfall varies greatly between different parts of the valley and ranges from about 400 millimeters in the south of the valley, the wind regime is dominated by regional patterns in the winter with occasional strong north-easterly wind storms known in Arabic as Sharkiyah. Prior to its drainage in the early 1950s, Lake Hula was 5.3 kilometers long and 4.4 kilometers wide and it was about one and a half meters deep in summer and three meters deep in winter. The lake attracted human settlement from prehistoric times. Paleolithic archaeological remains were found near the Bnot Yaakov bridge at the end of the valley. The first permanent settlement, Enan, dates from 9, 000-10,000 years ago and was discovered in the valley, the Hula Valley was a main junction on the important trade route connecting the large commercial centre of Damascus with the eastern Mediterranean coast and Egypt. During the Bronze Age, the cities of Hazor and Laish were built at key locations on this route approximately 4,000 years ago. At some point the area came under Israelite control until it was captured by the Assyrian armies of Tiglath-Pileser III, the Bible records lake Merom as the site of a victory of Joshua over the Canaanites. Throughout the Hellenistic, Roman, Byzantine and early Arab periods rural settlement in the Hula Valley was uninterrupted, during the Seleucid Empire, the town Seleucia Samulias was founded on the lake shore. Traditional crops were rice, cotton and sugar cane, sorghum, water buffalo were introduced in the eighth century supplying milk and serving as beasts of burden. In the 19th century, the valley, mainly marshy ground, John MacGregor, a Victorian adventurer, was captured with his boat, the Rob Roy, by dark-skinned Bedouin living in the Hula marshes

Sea of Galilee
–
The Sea of Galilee, also Kinneret, Lake of Gennesaret, or Lake Tiberias, is a large freshwater lake in Israel. It is approximately 53 km in circumference, about 21 km long and its area is 166.7 km2 at its fullest, and its maximum depth is approximately 43 m. At levels between 215 metres and 209 metres below sea level, it is the lowest freshwater lake on Earth, the lake is fed partly by underground springs although its main source is the Jordan River which flows through it from north to south. The Sea of Galilee is situated in northeast Israel, between the Golan Heights and the Galilee region, in the Jordan Rift Valley, the caused by the separation of the African and Arabian Plates. Consequently, the area is subject to earthquakes, and in the past and this is evident by the abundant basalt and other igneous rocks that define the geology of the Galilee. The lake has been called by different names throughout its history, with changing fate of the towns, the lakes name also changed. This name was found in the scripts of Ugarit, in the Aqhat Epic. Kinneret was listed among the cities in Joshua 19,35. A persistent, though likely erroneous popular etymology of the name presumes that the name Kinneret may originate from the Hebrew word kinnor, the scholarly consensus though is that the origin of the name lies with the important Bronze and Iron Age city of Kinneret, excavated at Tell el-Oreimeh. However, there is no evidence that the city of Kinneret itself was not named after the body of water rather than vice versa, or for the origin of the towns name. Sea of Ginosar The Babylonian Talmud, as well as Flavius Josephus mention the sea by the name Sea of Ginosar after the fertile plain of Ginosar that lies on its western side. Ginosar is yet another name derived from Kinneret, Sea of Tiberias is also the name mentioned in Roman texts and in the Jerusalem Talmud, and was adopted into Arabic as Buhairet Tabariyya, Lake Tiberias. This is the name employed by the medieval Persian and Arab scholars Al-Baladhuri, Al-Tabari, in 1989 remains of a hunter-gatherer site were found under the water at the southern end. Remains of mud huts were found which are the oldest known buildings in the world, the Sea of Galilee lies on the ancient Via Maris, which linked Egypt with the northern empires. The Greeks, Hasmoneans, and Romans founded flourishing towns and settlements on the lake including Hippos. The first-century historian Flavius Josephus was so impressed by the area that he wrote, Josephus also reported a thriving fishing industry at this time, with 230 boats regularly working in the lake. Archaeologists discovered one such boat, nicknamed the Jesus Boat, in 1986, much of the ministry of Jesus occurred on the shores of Lake Galilee. In those days, there was a ribbon development of settlements and villages around the lake and plenty of trade

Jordan Valley (Middle East)
–
The Jordan Valley forms part of the larger Jordan Rift Valley. This Rift Valley segment is 120 km long and 15 km wide. In a wider sense, the term may cover the Dead Sea basin and the Wadi Arabah or Arava valley. Over most of its length, the Jordan Valley forms the border between Jordan to the east, and Israel and the West Bank to the west, Israel has allocated 86% of the land to Israeli settlements. According to the used in this article, what is elsewhere sometimes termed the Upper Jordan Valley is not considered part of the Jordan Valley. The Upper Jordan Valley comprises the Jordan River sources and the course of the Jordan River through the Hula Valley, the northern part of the valley, known in Arabic as the Ghor, includes the Jordan River segment south of the Sea of Galilee. Several degrees warmer than adjacent areas, its year-round agricultural climate, fertile soils, south of the Dead Sea, the Jordan Valley contains the hot, dry southern part of the valley known as Wadi Araba, the wilderness or Arabah desert of the Bible. Prior to the 1967 Six-Day War, the valleys Jordanian side was home to about 60,000 people largely engaged in agriculture and pastoralism. By 1971, the Valleys Jordanian population had declined to 5,000 as a result of the 1967 war, investments by the Jordanian government in the region allowed the population to rebound to over 85,000 by 1979. 80% of the farms in the Jordanian part of the valley are family farms no larger than 30 dunams. Some 47,000 Palestinians live in the part of the valley lies in the West Bank in about twenty permanent communities. Thousands of Bedouins also live in temporary communities, since the end of the 1967 war, every Israeli government has considered the western Jordan Valley to be the eastern border of Israel with Jordan. The 1994 peace treaty between Israel and Jordan defines the border between the countries on the Jordan and Yarmouk Rivers in the center of those two river courses. In regard to the West Bank, Annex I provides that This line is the boundary between Jordan and the territory which came under Israeli military government control in 1967. Any treatment of this line shall be without prejudice to the status of the territory, in Area C of the West Bank, Israel has been steadily demolishing homes of Palestinians claiming a variety of rationales. In the context of pre-state Zionist and later Israeli settlement, Jordan Valley means the tip of the Sea of Galilee. In the late 1930s, the kibbutzim in the Jordan Valley formed the Council of the Gush, in the 1940s, this economic, cultural, and security cooperation between the kibbutzim continued, and a regional school system was established. In 1949, the Jordan Valley Regional Council was formed, becoming the model for regional councils throughout Israel, by about 3000 BCE, produce from the valley was being exported to neighboring regions

Dead Sea
–
The Dead Sea, is a salt lake bordered by Jordan to the east and Israel and Palestine to the west. Its surface and shores are 430.5 metres below sea level, the Dead Sea is 304 m deep, the deepest hypersaline lake in the world. With 34. 2% salinity, it is 9.6 times as salty as the ocean and this salinity makes for a harsh environment in which plants and animals cannot flourish, hence its name. The Dead Sea is 50 kilometres long and 15 kilometres wide at its widest point and it lies in the Jordan Rift Valley and its main tributary is the Jordan River. The Dead Sea has attracted visitors from around the Mediterranean basin for thousands of years and it was one of the worlds first health resorts, and it has been the supplier of a wide variety of products, from asphalt for Egyptian mummification to potash for fertilizers. People also use the salt and the minerals from the Dead Sea to create cosmetics, the Dead Sea water has a density of 1.24 kg/litre, which makes swimming similar to floating. The Dead Sea is receding at an alarming rate, multiple canals and pipelines were proposed to reduce its recession, which had begun causing many problems. The Red Sea–Dead Sea Water Conveyance project, carried out by Jordan, will provide water to neighboring countries, the first phase of the project is scheduled to begin in 2018 and be completed in 2021. In Hebrew, the Dead Sea is Yām ha-Melaḥ, meaning sea of salt, the Bible uses this term alongside two others, the Sea of the Arabah, and the Eastern Sea. The designation Dead Sea never appears in the Bible, in prose sometimes the term Yām ha-Māvet is used, due to the scarcity of aquatic life there. In Arabic the Dead Sea is called al-Bahr al-Mayyit, or less commonly baḥrᵘ lūṭᵃ, another historic name in Arabic was the Sea of Zoʼar, after a nearby town in biblical times. The Greeks called it Lake Asphaltites, the Dead Sea is an endorheic lake located in the Jordan Rift Valley, a geographic feature formed by the Dead Sea Transform. This left lateral-moving transform fault lies along the plate boundary between the African Plate and the Arabian Plate. It runs between the East Anatolian Fault zone in Turkey and the end of the Red Sea Rift offshore of the southern tip of Sinai. It is here that the Upper Jordan River/Sea of Galilee/Lower Jordan River water system comes to an end. The Jordan River is the major water source flowing into the Dead Sea, although there are small perennial springs under and around the Dead Sea, forming pools. The Mujib River, biblical Arnon, is one the larger sources of the Dead Sea other than the Jordan. The Wadi Mujib valley,420 m below the sea level in the southern of Jordan valley, is a biosphere reserve, other more substantial sources are Wadi Darajeh /Nahal Dragot, and Nahal Arugot

Arabah
–
The Arabah, known in Hebrew as Arava or Aravah, is a geographic name for the area south of the Dead Sea basin which forms part of the border between Israel to the west and Jordan to the east. This included the Jordan River Valley between Sea of Galilee and Dead Sea, the Dead Sea itself, and what is called today the Arava Valley. The modern use of the term is restricted to this section alone. The southern stretch of the Arabah is 166 km in length from the Gulf of Aqaba to the shore of the Dead Sea. Topographically, the region is divided into three sections, from this crest, the land slopes gently northward over the next 74 km to a point 15 km south of the Dead Sea. In the last section, the Arabah drops steeply to the Dead Sea, the Arabah is scenic with colorful cliffs and sharp-topped mountains. The southern Arabah is hot and dry and virtually without rain, there are numerous species of flora and fauna in the Aravah Valley. Notably the Caracal, Caracal caracal, is found on savannas of the valley, in Biblical times, the Arava was a center of copper production, King Solomon is believed to have had mines here based on copper mines dating to his reign. The Arabah was home to the Edomites, east of the Arabah was the domain of the Nabateans, the builders of the city of Petra. Kibbutz Yotvata founded in 1957, was named for an ancient town in the mentioned in the Bible. Kibbutz Lotan has a bird-watching center, the oldest moshav in the central Arava area is Ein Yahav. The Israel–Jordan Peace Treaty was signed in the Arava on October 26,1994, the governments of Jordan and Israel are promoting development of the region. There is a plan to bring sea water from the Red Sea to the Dead Sea through a canal and this project was once an issue of dispute between Jordan and Israel, but it was recently agreed that the project shall be constructed on and by the Jordanian side. In 2004, the Jordanian administrative district of Wadi Araba had a population of 6,775, the main economic activities for these Arabah residents revolve around herding sheep, agriculture, handicrafts, and the Jordanian Army. Timna Valley Park is notable for its rock carvings, some of the oldest copper mines in the world. On the Jordanian side is the famous Wadi Rum, which is famous among rock climbers, hikers, campers, Feynan Ecolodge was opened in Wadi Feynan by the Royal Society for the Conservation of Nature in 2005. Below is a list of Jordanian population clusters in Wadi Araba, The total population of the Jordanian portion of the region is 103,000, below is a list of Israeli localities in the Arava, from north to south. The population of the Israeli portion is 52,000, of which 47,500 live in Eilat, and just over 5,000 live in 20 small towns north of Eilat, the Israeli residents of the region are almost entirely Jews

Gulf of Aqaba
–
The Gulf of Aqaba or Gulf of Eilat is a large gulf at the northern tip of the Red Sea, east of the Sinai Peninsula and west of the Arabian mainland. Its coastline is divided between four countries, Egypt, Israel, Jordan, and Saudi Arabia, the gulf is east of the Sinai Peninsula and west of the Arabian Peninsula. With the Gulf of Suez to the west, it extends from the portion of the Red Sea. It reaches a depth of 1,850 m in its central area. The gulf measures 24 kilometres at its widest point and stretches some 160 kilometres north from the Straits of Tiran to where Israel meets Egypt, like the coastal waters of the Red Sea, the gulf is one of the worlds premier sites for diving. At this northern end of the gulf are three important cities, Taba in Egypt, Eilat in Israel, and Aqaba in Jordan and they are strategically important commercial ports and popular resorts for tourists seeking to enjoy the warm climate. Further south, Haql is the largest Saudi Arabian city on the gulf, on Sinai, Sharm el-Sheikh and Dahab are the major centers. The largest population center is Aqaba, with a population of 108,000, followed by Eilat with a population of 48,000. The gulf is one of two created by the Sinai Peninsulas bifurcation of the northern Red Sea, the Gulf of Suez lying to the west of the peninsula. Geologically, the forms the southern end of the Dead Sea Transform. It contains three small pull-apart basins, the Elat Deep, Aragonese Deep and Dakar Deep, formed between four left lateral strike-slip fault segments, movement on one of these faults caused the 1995 Gulf of Aqaba earthquake. Trade across the Red Sea between Thebes port of Elim and Elat at the head of the gulf is documented as early as the Fourth Dynasty of Egypt, egyptian settlements near Timna at the head of the gulf date to the Eighteenth dynasty of Egypt. At the northern edge, the ancient city of Ayla was a hub for the Nabateans. The Romans built the Via Traiana Nova, which joined the Kings Highway at Aqaba and connected Africa to Asia, Aqaba was a major Ottoman port, connected to Damascus and Medina by the Hejaz railway. During World War I, the Battle of Aqaba was the key battle that ended a 500-year Ottoman rule over Greater Syria, the gulf is one of the most popular diving destinations in the world. About 250,000 dives are performed annually in Eilats 11 km coastline, the Landscape of Wadi Rum to the east of the northern edge of the gulf is a popular destination. Other destinations are the ruins of the civilization of Ayla in the city of Aqaba. Whales, orcas, dolphins, dugongs, and whale sharks live in the gulf as well

Red Sea
–
The Red Sea is a seawater inlet of the Indian Ocean, lying between Africa and Asia. The connection to the ocean is in the south through the Bab el Mandeb strait, to the north lie the Sinai Peninsula, the Gulf of Aqaba, and the Gulf of Suez. The Red Sea is a Global 200 ecoregion, the sea is underlain by the Red Sea Rift which is part of the Great Rift Valley. The Red Sea has an area of roughly 438,000 km2, is about 2250 km long and. It has a depth of 2211 m in the central median trench. However, there are also extensive shallow shelves, noted for their marine life, the sea is the habitat of over 1,000 invertebrate species, and 200 soft and hard corals. It is the worlds northernmost tropical sea, the International Hydrographic Organization defines the limits of the Red Sea as follows, On the North. The Southern limits of the Gulfs of Suez and Aqaba, a line joining Husn Murad and Ras Siyyan. Red Sea is a translation of the Greek Erythra Thalassa, Latin Mare Rubrum, Arabic, البحر الأحمر. Al-Baḥr Al-Aḥmar, Somali Badda Cas and Tigrinya Qeyyiḥ bāḥrī, the name of the sea may signify the seasonal blooms of the red-coloured Trichodesmium erythraeum near the waters surface. A theory favored by modern scholars is that the name red is referring to the direction south. The basis of this theory is that some Asiatic languages used color words to refer to the cardinal directions, herodotus on one occasion uses Red Sea and Southern Sea interchangeably. Historically, it was known to western geographers as Mare Mecca. Some ancient geographers called the Red Sea the Arabian Gulf or Gulf of Arabia. C, in that version, the Yam Suph is translated as Erythra Thalassa. The Red Sea is one of four seas named in English after common color terms — the others being the Black Sea, the White Sea and the Yellow Sea. The direct rendition of the Greek Erythra thalassa in Latin as Mare Erythraeum refers to the part of the Indian Ocean. The earliest known exploration of the Red Sea was conducted by ancient Egyptians, one such expedition took place around 2500 BC, and another around 1500 BC. Both involved long voyages down the Red Sea, historically, scholars argued whether these trips were possible

Straits of Tiran
–
The Straits of Tiran are the narrow sea passages between the Sinai and Arabian peninsulas which separate the Gulf of Aqaba from the Red Sea proper. The distance between the two peninsulas is about 13 km, sanafir Island lies to the east of Tiran, southeast of the shallow strait between Tiran and Saudi Arabia. International documents inconsistently refer to both the Straits of Tiran and the Strait of Tiran, there are several passages formed by the islands between Egypt and Saudi Arabia. The westernmost strait, between Egypt and the island of Tiran, overlooked by the Egyptian city Sharm el-Sheikh is the Strait of Tiran,5 or 6 km wide and it has two passages deep enough to be navigable by large ships. The Enterprise passage,290 metres deep, is adjacent to the Egyptian side, while the 73-metre deep Grafton passage, surrounded by shallows, is to the east, nearer to the island of Tiran. To the east of Tiran, between it and Saudi Arabia, the strait has reefs and shallows with a single channel 16 metres deep. Access to Jordans only seaport of Aqaba and to Israels only Red Sea seaport of Eilat is through the Gulf of Aqaba, which gives the Straits of Tiran strategic importance. In 1967, ninety percent of Israeli oil passed through the Straits of Tiran, in May 1967, Israeli Prime Minister Levi Eshkol repeated declarations that Israel had made in 1957, saying that closure of the Straits of Tiran would be an act of war. Rikhye did withdraw, including from the port at Sharm el Sheikh adjacent to the straits, Egypt had initially requested UNEF withdrawal from locations other than Sharm el-Sheik, but UN Secretary-General U Thant demanded an all-or-nothing withdrawal. The right of innocent, maritime passage must be preserved for all nations, a project to build a 15-kilometre bridge across the straits, linking Egypt and Saudi Arabia, is under consideration by the Egyptian government.

Sinai Peninsula
–
The Sinai Peninsula or simply Sinai is a peninsula in Egypt, situated between the Mediterranean Sea to the north and the Red Sea to the south, serving as a land bridge between Asia and Africa. It is the part of Egyptian territory located in Asia. Sinai has an area of about 60,000 km2. The bulk of the peninsula is divided administratively into two of Egypts 27 governorates, the Sinai Peninsula has been a part of Egypt from the First Dynasty of ancient Egypt. In periods of occupation, the Sinai was, like the rest of Egypt, also occupied and controlled by foreign empires, in more recent history the Ottoman Empire. Israel invaded and occupied Sinai during the Suez Crisis of 1956, on 6 October 1973, Egypt launched the Yom Kippur War to retake the peninsula, which was the site of fierce fighting between Egyptian and Israeli forces. Today, Sinai has become a tourist destination due to its setting, rich coral reefs. Mount Sinai is one of the most religiously significant places in Abrahamic faiths, in addition to its formal name, Egyptians also refer to it as Arḍ ul-Fairūz. The ancient Egyptians called it Ta Mefkat, or land of turquoise, Sinai is triangular in shape, with northern shore lying on the southern Mediterranean Sea, and southwest and southeast shores on Gulf of Suez and Gulf of Aqaba of the Red Sea. It is linked to the African continent by the Isthmus of Suez,125 kilometres wide strip of land, the eastern isthmus, linking it to the Asian mainland, is around 200 kilometres wide. The peninsulas eastern shore separates the Arabian plate from the African plate, the southernmost tip is the Ras Muhammad National Park. Most of the Sinai Peninsula is divided among the two governorates of Egypt, South Sinai and North Sinai, together, they comprise around 60,000 square kilometres and have a population of 597,000. Three more governates span the Suez Canal, crossing into African Egypt, Suez is on the end of the Suez Canal, Ismailia in the centre. The largest city of Sinai is Arish, capital of the North Sinai, other larger settlements include Sharm el-Sheikh and El-Tor, on the southern coast. Inland Sinai is arid, mountainous and sparsely populated, the largest settlements being Saint Catherine, Sinai is one of the coldest provinces in Egypt because of its high altitudes and mountainous topographies. Winter temperatures in some of Sinais cities and towns reach −16 °C, the mines were worked intermittently and on a seasonal basis for thousands of years. Modern attempts to exploit the deposits have been unprofitable and these may be the first historically attested mines. According to the Hebrew Bible, the peninsula was crossed by the Israelites during the Exodus from Egypt and this included numerous halts over a 40-year period of travel sometime towards the end of the Bronze Age

Miocene
–
The Miocene is the first geological epoch of the Neogene Period and extends from about 23.03 to 5.333 million years ago. The Miocene was named by Sir Charles Lyell and its name comes from the Greek words μείων and καινός and means less recent because it has 18% fewer modern sea invertebrates than the Pliocene. The Miocene follows the Oligocene Epoch and is followed by the Pliocene Epoch, the earth went from the Oligocene through the Miocene and into the Pliocene, with the climate slowly cooling towards a series of ice ages. The Miocene boundaries are not marked by a single distinct global event, the apes arose and diversified during the Miocene, becoming widespread in the Old World. By the end of this epoch, the ancestors of humans had split away from the ancestors of the chimpanzees to follow their own evolutionary path, as in the Oligocene before it, grasslands continued to expand and forests to dwindle in extent. In the Miocene seas, kelp forests made their first appearance, the plants and animals of the Miocene were fairly modern. The Miocene faunal stages from youngest to oldest are typically named according to the International Commission on Stratigraphy, Two subdivisions each form the lower, middle, continents continued to drift toward their present positions. Mountain building took place in western North America, Europe, both continental and marine Miocene deposits are common worldwide with marine outcrops common near modern shorelines. Well studied continental exposures occur in the North American Great Plains, India continued to collide with Asia, creating dramatic new mountain ranges. The Tethys Seaway continued to shrink and then disappeared as Africa collided with Eurasia in the Turkish–Arabian region between 19 and 12 Ma. The subsequent uplift of mountains in the western Mediterranean region and a fall in sea levels combined to cause a temporary drying up of the Mediterranean Sea near the end of the Miocene. The global trend was towards increasing aridity caused primarily by global cooling reducing the ability of the atmosphere to absorb moisture, climates remained moderately warm, although the slow global cooling that eventually led to the Pleistocene glaciations continued. Although a long-term cooling trend was well underway, there is evidence of a period during the Miocene when the global climate rivalled that of the Oligocene. The Miocene warming began 21 million years ago and continued until 14 million years ago, by 8 million years ago, temperatures dropped sharply once again, and the Antarctic ice sheet was already approaching its present-day size and thickness. Greenland may have begun to have large glaciers as early as 7 to 8 million years ago, life during the Miocene Epoch was mostly supported by the two newly formed biomes, kelp forests and grasslands. This allows for more grazers, such as horses, rhinoceroses, ninety five percent of modern plants existed by the end of this epoch. The higher organic content and water retention of the deeper and richer grassland soils, with long term burial of carbon in sediments, produced a carbon and this, combined with higher surface albedo and lower evapotranspiration of grassland, contributed to a cooler, drier climate. The expansion of grasslands and radiations among terrestrial herbivores correlates to fluctuations in CO2

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

Mediterranean Sea
–
The sea is sometimes considered a part of the Atlantic Ocean, although it is usually identified as a separate body of water. The name Mediterranean is derived from the Latin mediterraneus, meaning inland or in the middle of land and it covers an approximate area of 2.5 million km2, but its connection to the Atlantic is only 14 km wide. The Strait of Gibraltar is a strait that connects the Atlantic Ocean to the Mediterranean Sea and separates Gibraltar. In oceanography, it is called the Eurafrican Mediterranean Sea or the European Mediterranean Sea to distinguish it from mediterranean seas elsewhere. The Mediterranean Sea has a depth of 1,500 m. The sea is bordered on the north by Europe, the east by Asia and it is located between latitudes 30° and 46° N and longitudes 6° W and 36° E. Its west-east length, from the Strait of Gibraltar to the Gulf of Iskenderun, the seas average north-south length, from Croatia’s southern shore to Libya, is approximately 800 km. The Mediterranean Sea, including the Sea of Marmara, has an area of approximately 2,510,000 square km. The sea was an important route for merchants and travelers of ancient times that allowed for trade, the history of the Mediterranean region is crucial to understanding the origins and development of many modern societies. In addition, the Gaza Strip and the British Overseas Territories of Gibraltar and Akrotiri, the term Mediterranean derives from the Latin word mediterraneus, meaning amid the earth or between land, as it is between the continents of Africa, Asia and Europe. The Ancient Greek name Mesogeios, is similarly from μέσο, between + γη, land, earth) and it can be compared with the Ancient Greek name Mesopotamia, meaning between rivers. The Mediterranean Sea has historically had several names, for example, the Carthaginians called it the Syrian Sea and latter Romans commonly called it Mare Nostrum, and occasionally Mare Internum. Another name was the Sea of the Philistines, from the people inhabiting a large portion of its shores near the Israelites, the sea is also called the Great Sea in the General Prologue by Geoffrey Chaucer. In Ottoman Turkish, it has also been called Bahr-i Sefid, in Modern Hebrew, it has been called HaYam HaTikhon, the Middle Sea, reflecting the Seas name in ancient Greek, Latin, and modern languages in both Europe and the Middle East. Similarly, in Modern Arabic, it is known as al-Baḥr al-Mutawassiṭ, in Turkish, it is known as Akdeniz, the White Sea since among Turks the white colour represents the west. Several ancient civilisations were located around the Mediterranean shores, and were influenced by their proximity to the sea. It provided routes for trade, colonisation, and war, as well as food for numerous communities throughout the ages, due to the shared climate, geology, and access to the sea, cultures centered on the Mediterranean tended to have some extent of intertwined culture and history. Two of the most notable Mediterranean civilisations in classical antiquity were the Greek city states, later, when Augustus founded the Roman Empire, the Romans referred to the Mediterranean as Mare Nostrum

Oligocene
–
The Oligocene is a geologic epoch of the Paleogene Period and extends from about 33.9 million to 23 million years before the present. As with other geologic periods, the rock beds that define the epoch are well identified but the exact dates of the start. The name Oligocene comes from the Ancient Greek ὀλίγος and καινός, the Oligocene is preceded by the Eocene Epoch and is followed by the Miocene Epoch. The Oligocene is the third and final epoch of the Paleogene Period, the Oligocene is often considered an important time of transition, a link between the archaic world of the tropical Eocene and the more modern ecosystems of the Miocene. Major changes during the Oligocene included an expansion of grasslands. By contrast, the Oligocene–Miocene boundary is not set at an easily identified worldwide event, Oligocene faunal stages from youngest to oldest are, The Paleogene Period general temperature decline is interrupted by an Oligocene 7-million-year stepwise climate change. A deeper 8.2 °C,400, 000-year temperature depression leads the 2 °C, the stepwise climate change began 32.5 Ma and lasted through to 25.5 Ma, as depicted in the PaleoTemps chart. The Oligocene climate change was a increase in ice volume. The 7-million-year depression abruptly terminated within 1–2 million years of the La Garita Caldera eruption at 28–26 Ma, a deep 400, 000-year glaciated Oligocene Miocene boundary event is recorded at McMurdo Sound and King George Island. During this epoch, the continued to drift toward their present positions. Antarctica became more isolated and finally developed an ice cap, a brief marine incursion marks the early Oligocene in Europe. Marine fossils from the Oligocene are rare in North America, there appears to have been a land bridge in the early Oligocene between North America and Europe, since the faunas of the two regions are very similar. Sometime during the Oligocene, South America was finally detached from Antarctica and it also allowed the Antarctic Circumpolar Current to flow, rapidly cooling the Antarctic continent. Angiosperms continued their expansion throughout the world as tropical and sub-tropical forests were replaced by deciduous forests. Open plains and deserts became more common and grasses expanded from their habitat in the Eocene moving out into open tracts. However, even at the end of the period, grass was not quite enough for modern savannas. In North America, subtropical species dominated with cashews and lychee trees present, and temperate trees such as roses, beeches, the legumes spread, while sedges, bulrushes, and ferns continued their ascent. Even more open landscapes allowed animals to grow to larger sizes than they had earlier in the Paleocene epoch 30 million years earlier, marine faunas became fairly modern, as did terrestrial vertebrate fauna on the northern continents

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

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.

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. After Alexander the Greats conquest, the area was Hellenized, a process continued under the Roman Empire. The Seljuk Sultanate of Rûm ruled Anatolia until the Mongol invasion in 1243, the empire reached the peak of its power in the 16th century, especially during the reign of Suleiman the Magnificent. During the war, the Ottoman government committed genocides against its Armenian, Assyrian, following the war, the conglomeration of territories and peoples that formerly comprised the Ottoman Empire was partitioned into several new states. Turkey is a member of the UN, an early member of NATO. Turkeys growing economy and diplomatic initiatives have led to its recognition as a regional power while her location has given it geopolitical, the name of Turkey is based on the ethnonym Türk. The first recorded use of the term Türk or Türük as an autonym is contained in the Old Turkic inscriptions of the Göktürks of Central Asia, the English name Turkey first appeared in the late 14th century and is derived from Medieval Latin Turchia. Similarly, the medieval Khazar Empire, a Turkic state on the shores of the Black. The medieval Arabs referred to the Mamluk Sultanate as al-Dawla al-Turkiyya, the Ottoman Empire was sometimes referred to as Turkey or the Turkish Empire among its European contemporaries. The Anatolian peninsula, comprising most of modern Turkey, is one of the oldest permanently settled regions in the world, various ancient Anatolian populations have lived in Anatolia, from at least the Neolithic period until the Hellenistic period. Many of these peoples spoke the Anatolian languages, a branch of the larger Indo-European language family, in fact, given the antiquity of the Indo-European Hittite and Luwian languages, some scholars have proposed Anatolia as the hypothetical centre from which the Indo-European languages radiated. The European part of Turkey, called Eastern Thrace, has also been inhabited since at least forty years ago. It is the largest and best-preserved Neolithic site found to date, the settlement of Troy started in the Neolithic Age and continued into the Iron Age

Global Positioning System
–
The Global Positioning System is a space-based radionavigation system owned by the United States government and operated by the United States Air Force. The GPS system operates independently of any telephonic or internet reception, the GPS system provides critical positioning capabilities to military, civil, and commercial users around the world. The United States government created the system, maintains it, however, the US government can selectively deny access to the system, as happened to the Indian military in 1999 during the Kargil War. The U. S. Department of Defense developed the system and it became fully operational in 1995. Roger L. Easton of the Naval Research Laboratory, Ivan A, getting of The Aerospace Corporation, and Bradford Parkinson of the Applied Physics Laboratory are credited with inventing it. Announcements from Vice President Al Gore and the White House in 1998 initiated these changes, in 2000, the U. S. Congress authorized the modernization effort, GPS III. In addition to GPS, other systems are in use or under development, mainly because of a denial of access. The Russian Global Navigation Satellite System was developed contemporaneously with GPS, GLONASS can be added to GPS devices, making more satellites available and enabling positions to be fixed more quickly and accurately, to within two meters. There are also the European Union Galileo positioning system and Chinas BeiDou Navigation Satellite System, special and general relativity predict that the clocks on the GPS satellites would be seen by the Earths observers to run 38 microseconds faster per day than the clocks on the Earth. The GPS calculated positions would quickly drift into error, accumulating to 10 kilometers per day, the relativistic time effect of the GPS clocks running faster than the clocks on earth was corrected for in the design of GPS. The Soviet Union launched the first man-made satellite, Sputnik 1, two American physicists, William Guier and George Weiffenbach, at Johns Hopkinss Applied Physics Laboratory, decided to monitor Sputniks radio transmissions. Within hours they realized that, because of the Doppler effect, the Director of the APL gave them access to their UNIVAC to do the heavy calculations required. The next spring, Frank McClure, the deputy director of the APL, asked Guier and Weiffenbach to investigate the inverse problem — pinpointing the users location and this led them and APL to develop the TRANSIT system. In 1959, ARPA also played a role in TRANSIT, the first satellite navigation system, TRANSIT, used by the United States Navy, was first successfully tested in 1960. It used a constellation of five satellites and could provide a navigational fix approximately once per hour, in 1967, the U. S. Navy developed the Timation satellite, which proved the feasibility of placing accurate clocks in space, a technology required by GPS. In the 1970s, the ground-based OMEGA navigation system, based on comparison of signal transmission from pairs of stations. Limitations of these systems drove the need for a more universal navigation solution with greater accuracy, during the Cold War arms race, the nuclear threat to the existence of the United States was the one need that did justify this cost in the view of the United States Congress. This deterrent effect is why GPS was funded and it is also the reason for the ultra secrecy at that time

Precipitation
–
In meteorology, precipitation is any product of the condensation of atmospheric water vapor that falls under gravity. The main forms of precipitation include drizzle, rain, sleet, snow, graupel, Precipitation occurs when a portion of the atmosphere becomes saturated with water vapor, so that the water condenses and precipitates. Thus, fog and mist are not precipitation but suspensions, because the vapor does not condense sufficiently to precipitate. Two processes, possibly acting together, can lead to air becoming saturated, Precipitation forms as smaller droplets coalesce via collision with other rain drops or ice crystals within a cloud. Short, intense periods of rain in scattered locations are called showers, moisture that is lifted or otherwise forced to rise over a layer of sub-freezing air at the surface may be condensed into clouds and rain. This process is active when freezing rain is occurring. A stationary front is often present near the area of freezing rain, provided necessary and sufficient atmospheric moisture content, the moisture within the rising air will condense into clouds, namely stratus and cumulonimbus. Eventually, the droplets will grow large enough to form raindrops. Lake-effect snowfall can be locally heavy, thundersnow is possible within a cyclones comma head and within lake effect precipitation bands. In mountainous areas, heavy precipitation is possible where upslope flow is maximized within windward sides of the terrain at elevation, on the leeward side of mountains, desert climates can exist due to the dry air caused by compressional heating. The movement of the trough, or intertropical convergence zone. Precipitation is a component of the water cycle, and is responsible for depositing the fresh water on the planet. Approximately 505,000 cubic kilometres of water falls as precipitation each year,398,000 cubic kilometres of it over the oceans and 107,000 cubic kilometres over land. Given the Earths surface area, that means the globally averaged annual precipitation is 990 millimetres, Climate classification systems such as the Köppen climate classification system use average annual rainfall to help differentiate between differing climate regimes. Precipitation may occur on celestial bodies, e. g. when it gets cold, Mars has precipitation which most likely takes the form of frost. Precipitation is a component of the water cycle, and is responsible for depositing most of the fresh water on the planet. Approximately 505,000 km3 of water falls as precipitation each year,398,000 km3 of it over the oceans, given the Earths surface area, that means the globally averaged annual precipitation is 990 millimetres. Mechanisms of producing precipitation include convective, stratiform, and orographic rainfall, Precipitation can be divided into three categories, based on whether it falls as liquid water, liquid water that freezes on contact with the surface, or ice

Relative humidity
–
Relative humidity is the ratio of the partial pressure of water vapor to the equilibrium vapor pressure of water at a given temperature. Relative humidity depends on temperature and the pressure of the system of interest and it requires less water vapor to attain high relative humidity at low temperatures, more water vapour is required to attain high relative humidity in warm or hot air. Humans are sensitive to high humidity because the body uses evaporative cooling, enabled by perspiration. Perspiration evaporates from the more slowly under humid conditions than under arid. For example, if the air temperature is 24 °C and the humidity is zero percent. If the relative humidity is 100 percent at the air temperature. In other words, if the air is 24 °C and contains saturated water vapor, then the human body cools itself at the rate as it would if it were 27 °C. The heat index and the humidex are indices that reflect the effect of temperature. In cold climates, the temperature causes lower capacity for water vapour to flow about. Dry cracked skin can result from dry air, low humidity causes tissue lining nasal passages to dry, crack and become more susceptible to penetration of Rhinovirus cold viruses. Low humidity is a cause of nosebleeds. The use of a humidifier in homes, especially bedrooms, can help with these symptoms, indoor relative humidities should be kept above 30% to reduce the likelihood of the occupants nasal passages drying out. Humans can be comfortable within a range of humidities depending on the temperature—from thirty to seventy percent—but ideally between 50% and 60%. Very low humidity can create discomfort, respiratory problems, and aggravate allergies in some individuals, in the winter, it is advisable to maintain relative humidity at 30 percent or above. Extremely low relative humidities may also cause eye irritation, wooden furniture can shrink, causing the paint that covers these surfaces to fracture. When the temperature is low and the humidity is high. When relative humidity approaches 100 percent, condensation can occur on surfaces, leading to problems with mold, corrosion, decay, condensation can pose a safety risk as it can promote the growth of mold and wood rot as well as possibly freezing emergency exits shut. The basic principles for buildings, above, also apply to vehicles, in addition, there may be safety considerations

Geography of Israel
–
The geography of Israel is very diverse, with desert conditions in the south, and snow-capped mountains in the north. Israel is located at 31°30′N 34°45′E at the end of the Mediterranean Sea in western Asia. It is bounded to the north by Lebanon, the northeast by Syria, the east by Jordan and the West Bank, to the west of Israel is the Mediterranean Sea, which makes up the majority of Israels 273 km coastline and the Gaza Strip. Israel has a coastline on the Red Sea in the south. Israels area is approximately 20,770 km2, which includes 445 km2 of inland water, Israel stretches 424 km from north to south, and its width ranges from 114 km to, at its narrowest point,15 km. The Israeli-occupied territories include the West Bank,5,879 km2, East Jerusalem,70 km2, geographical features in these territories will be noted as such. Southern Israel is dominated by the Negev desert, covering some 16,000 square kilometres, the north of the Negev contains the Judean Desert, which, at its border with Jordan, contains the Dead Sea which, at −417 m is the lowest point on Earth. The inland area of central Israel is dominated by the Judean Hills of the West Bank, whilst the central and northern coastline consists of the flat and fertile Israeli coastal plain. Inland, the region contains the Mount Carmel mountain range, which is followed inland by the fertile Jezreel Valley. The highest point in territory internationally recognized as Israeli is Mount Meron at 1,208 meters, Israel lies to the north of the equator around 31°30 north latitude and 34°45 east longitude. It measures 424 km from north to south and, at its widest point 114 km, at its narrowest point, however, this is reduced to just 15 km. It has a frontier of 1,017 km and a coastline of 273 km. It is ranked 153 on the List of countries and outlying territories by total area, prior to the establishment of the British Mandate for Palestine, there was no clear-cut definition of the geographical and territorial limits of the area known as Palestine. On the eve of World War I it was described by Encyclopædia Britannica as a geographical concept. The Sykes-Picot Treaty in 1916 divided the region later became Palestine into four political units. Under the British Mandate for Palestine, the first geo-political framework was created that distinguished the area from the countries that surrounded it. The boundary demarcation at this time did not introduce geographical changes near the frontiers, modern Israel is bounded to the north by Lebanon, the northeast by Syria, the east by Jordan and the West Bank, and to the southwest by Egypt. To the west of Israel is the Mediterranean Sea, which makes up the majority of Israels 273 km coastline, Israel has a small coastline on the Red Sea in the south

Geography of Jordan
–
The territory of Jordan now covers about 91,880 square kilometres. Jordan is landlocked except at its extremity, where nearly 26 kilometres of shoreline along the Gulf of Aqaba provide access to the Red Sea. Geographic coordinates, 31°00′N 36°00′E Except for small sections of the borders with Israel and Syria, the countrys boundaries were established by various international agreements and with the exception of the border with Israel, none was in dispute in early 1989. In 1965 Jordan and Saudi Arabia concluded an agreement that realigned and delimited the boundary, the realignment resulted in some exchange of territory, and Jordans coastline on the Gulf of Aqaba was lengthened by about 18 kilometres. The new boundary enabled Jordan to expand its facilities and established a zone in which the two parties agreed to share petroleum revenues equally if oil were discovered. The agreement also protected the pasturage and watering rights of nomadic tribes inside the exchanged territories, the country consists mainly of a plateau between 700 metres and 1,200 metres meters high, divided into ridges by valleys and gorges, and a few mountainous areas. West of the plateau, land form the East Bank of the Jordan Rift Valley. The valley is part of the north-south Great Rift Valley, and its successive depressions are Lake Tiberias, Jordan Valley, the Dead Sea, Arabah, Jordans western border follows the bottom of the rift. Although an earthquake-prone region, no severe shocks had been recorded for several centuries, by far the greatest part of the East Bank is desert, displaying the land forms and other features associated with great aridity. Most of this land is part of the Syrian Desert and northern Arabian Desert, there are broad expanses of sand and dunes, particularly in the south and southeast, together with salt flats. Occasional jumbles of sandstone hills or low mountains support only meager and these areas support little life and are the least populated regions of Jordan. The drainage network is coarse and incised, in many areas the relief provides no eventual outlet to the sea, so that sedimentary deposits accumulate in basins where moisture evaporates or is absorbed in the ground. Occasional summits in this region reach 1,200 meters in the part and exceed 1,700 meters in the southern part. These highlands are an area of long-settled villages, the western edge of this plateau country forms an escarpment along the eastern side of the Jordan River-Dead Sea depression and its continuation south of the Dead Sea. Most of the wadis that provide drainage from the country into the depression carry water only during the short season of winter rains. Sharply incised with deep, canyon-like walls, whether flowing or dry the wadis can be formidable obstacles to travel. The Jordan River is short, but from its headwaters the riverbed drops from an elevation of about 3,000 meters above sea level to more than 400 meters below sea level. Before reaching Jordanian territory the river forms the Sea of Galilee, the Jordan Rivers principal tributary is the Yarmouk River

Great Rift Valley
–
The Great Rift Valley is a name given to the continuous geographic trench, approximately 6,000 kilometres in length, that runs from Lebanons Beqaa Valley in Asia to Mozambique in South Eastern Africa. The name continues in some usages, although it is considered geologically imprecise as it combines features that are today regarded as separate, although related, rift. Geologists generally refer to these incipient plates as the Nubian Plate and it included what we would call today the Lebanese section of the Dead Sea Transform, the Jordan Rift Valley, Red Sea Rift and the East African Rift. Today these rifts and faults are seen as distinct, although connected and these were only formed 35 million years ago. The northernmost part of the Rift corresponds to the section of what is called today the Dead Sea Transform or Rift. This midsection of the DST forms the Beqaa Valley in Lebanon, further south it is known as the Hula Valley separating the Galilee mountains and the Golan Heights. The River Jordan begins here and flows southward through Lake Hula into the Sea of Galilee in Israel, the Rift then continues south through the Jordan Rift Valley into the Dead Sea on the Israeli-Jordanian border. From the Dead Sea southwards, the Rift is occupied by the Wadi Arabah, then the Gulf of Aqaba, off the southern tip of Sinai in the Red Sea, the Dead Sea Transform meets the Red Sea Rift which runs the length of the Red Sea. The Red Sea Rift comes ashore to meet the East African Rift, the junction of these three rifts is called the Afar Triple Junction. The East African rift has two branches, the Western Rift Valley and the Eastern Rift Valley, the Western Rift, also called the Albertine Rift, is bordered by some of the highest mountains in Africa, including the Virunga Mountains, Mitumba Mountains, and Ruwenzori Range. It contains the Rift Valley lakes, which some of the deepest lakes in the world. Lake Victoria is considered to be part of the valley system although it actually lies between the two branches. All of the African Great Lakes were formed as the result of the rift, in Kenya, the valley is deepest to the north of Nairobi

Wayback Machine
–
The Internet Archive launched the Wayback Machine in October 2001. It was set up by Brewster Kahle and Bruce Gilliat, and is maintained with content from Alexa Internet, the service enables users to see archived versions of web pages across time, which the archive calls a three dimensional index. Since 1996, the Wayback Machine has been archiving cached pages of websites onto its large cluster of Linux nodes and it revisits sites every few weeks or months and archives a new version. Sites can also be captured on the fly by visitors who enter the sites URL into a search box, the intent is to capture and archive content that otherwise would be lost whenever a site is changed or closed down. The overall vision of the machines creators is to archive the entire Internet, the name Wayback Machine was chosen as a reference to the WABAC machine, a time-traveling device used by the characters Mr. Peabody and Sherman in The Rocky and Bullwinkle Show, an animated cartoon. These crawlers also respect the robots exclusion standard for websites whose owners opt for them not to appear in search results or be cached, to overcome inconsistencies in partially cached websites, Archive-It. Information had been kept on digital tape for five years, with Kahle occasionally allowing researchers, when the archive reached its fifth anniversary, it was unveiled and opened to the public in a ceremony at the University of California, Berkeley. Snapshots usually become more than six months after they are archived or, in some cases, even later. The frequency of snapshots is variable, so not all tracked website updates are recorded, Sometimes there are intervals of several weeks or years between snapshots. After August 2008 sites had to be listed on the Open Directory in order to be included. As of 2009, the Wayback Machine contained approximately three petabytes of data and was growing at a rate of 100 terabytes each month, the growth rate reported in 2003 was 12 terabytes/month, the data is stored on PetaBox rack systems manufactured by Capricorn Technologies. In 2009, the Internet Archive migrated its customized storage architecture to Sun Open Storage, in 2011 a new, improved version of the Wayback Machine, with an updated interface and fresher index of archived content, was made available for public testing. The index driving the classic Wayback Machine only has a bit of material past 2008. In January 2013, the company announced a ground-breaking milestone of 240 billion URLs, in October 2013, the company announced the Save a Page feature which allows any Internet user to archive the contents of a URL. This became a threat of abuse by the service for hosting malicious binaries, as of December 2014, the Wayback Machine contained almost nine petabytes of data and was growing at a rate of about 20 terabytes each week. Between October 2013 and March 2015 the websites global Alexa rank changed from 162 to 208, in a 2009 case, Netbula, LLC v. Chordiant Software Inc. defendant Chordiant filed a motion to compel Netbula to disable the robots. Netbula objected to the motion on the ground that defendants were asking to alter Netbulas website, in an October 2004 case, Telewizja Polska USA, Inc. v. Echostar Satellite, No.02 C3293,65 Fed. 673, a litigant attempted to use the Wayback Machine archives as a source of admissible evidence, Telewizja Polska is the provider of TVP Polonia and EchoStar operates the Dish Network

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
