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

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

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

Oasis
–
In geography, an oasis is an isolated area of vegetation in a desert, typically surrounding a spring or similar water source, such as a pond or small lake. Oases also provide habitat for animals and even if the area is big enough. The location of oases has been of importance for trade and transportation routes in desert areas, caravans must travel via oases so that supplies of water. Thus, political or military control of an oasis has in many cases meant control of trade on a particular route. For example, the oases of Awjila, Ghadames, and Kufra, oases are formed from underground rivers or aquifers such as an artesian aquifer, where water can reach the surface naturally by pressure or by man-made wells. Occasional brief thunderstorms provide subterranean water to sustain natural oases, such as the Tuat, substrata of impermeable rock and stone can trap water and retain it in pockets, or on long faulting subsurface ridges or volcanic dikes water can collect and percolate to the surface. Any incidence of water is used by migrating birds, which also pass seeds with their droppings which will grow at the waters edge forming an oasis. It can also be used to plant crops, the word oasis came into English via Latin, oasis from Ancient Greek, ὄασις óasis, which in turn is a direct borrowing from Demotic Egyptian. The word for oasis in the later attested Coptic language is wahe or ouahe which means a dwelling place, people who live in an oasis must manage land and water use carefully, fields must be irrigated to grow plants like apricots, dates, figs, and olives. The most important plant in an oasis is the date palm and these palm trees provide shade for smaller trees like peach trees, which form the middle layer. By growing plants in different layers, the farmers make best use of the soil, many vegetables are also grown and some cereals, such as barley, millet, and wheat, are grown where there is more moisture. Great Man-Made River – the worlds largest irrigation project, developed in Libya to connect cities with fossil water.

Nature reserve
–
Nature reserves may be designated by government institutions in some countries, or by private landowners, such as charities and research institutions, regardless of nationality. Nature reserves fall into different IUCN categories depending on the level of protection afforded by local laws, early reservations often had a religious underpinning, such as the evil forest areas of West Africa which were forbidden to humans, who were threatened with spiritual attack if they went there. Sacred areas taboo from human entry to fishing and hunting are known by ancient cultures worldwide. The worlds first modern nature reserve was established in 1821 by the naturalist and explorer Charles Waterton around his estate in Walton Hall and he spent £9000 on the construction of a 3 mile long,9 ft tall wall to enclose his park from poachers. He tried to encourage birdlife by planting trees and hollowing out trunks for owls to nest in and he also invented artificial nest boxes to house starlings, jackdaws and sand martins and unsuccessfully attempted to introduce little owls from Italy. Drachenfels was protected as the first state-designated nature reserve in modern-day Germany, in Australia, a nature reserve is the title of a type of protected area used in the jurisdictions of the Australian Capital Territory, New South Wales, Tasmania and Western Australia. The term “nature reserve” is defined in the relevant statutes used in those states and territories rather than by a national statute. As of 2014,1767 out of a total of 10339 protected areas listed within the Australian National Reserve System used the term “nature reserve in their names, in Brazil, nature reserves are classified as ecological stations or biological reserves by the National System of Conservation Units. Their main objectives are preserving fauna and flora and other natural attributes, visits are allowed only with permission, and only for educational or scientific purposes. Changes to the ecosystems in both types of reserve are allowed to restore and preserve the balance, biological diversity. Ecological stations are allowed to change the environment within strictly defined limits for the purpose of scientific research. A wildlife reserve in Brazil is also protected, and hunting is not allowed, there are 30 nature reserves in Egypt which cover 12% of Egyptian land. Those nature reserves were built according to the laws no, 102/1983 and 4/1994 for protection of the Egyptian nature reserve. Egypt announced a plan from to build 40 nature reserves from 1997 to 2017, to protect the natural resources. The largest nature reserve in Egypt is Gebel Elba in the southeast, denmark has three national parks and several nature reserves, some of them inside the national park areas. The largest single reserve is Hanstholm Nature Reserve, which covers 40 km2 and is part of Thy National Park, in Sweden there are 29 national parks. The first of them were established in 1909, in fact, Sweden was the first European country that established 9 national parks. There are almost 4,000 nature reserves in Sweden and they comprise about 85% of the surface that is protected by the Swedish Enironmental Code

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

Masada
–
Masada is an ancient fortification in the Southern District of Israel situated on top of an isolated rock plateau, akin to a mesa. It is located on the edge of the Judaean Desert. Herod the Great built palaces for himself on the mountain and fortified Masada between 37 and 31 BCE, Masada is one of Israels most popular tourist attractions. The cliff of Masada is, geologically speaking, a horst, as the cliffs on the east edge of Masada are about 400 m high, and the cliffs on the west are about 90 m high, the natural approaches to the cliff top are very difficult to navigate. The top of the plateau is flat and rhomboid-shaped, about 550 m by 270 m. Three narrow, winding paths led from below up to fortified gates, almost all historical information about Masada comes from the first-century Jewish Roman historian Josephus. Josephus writes that the site was first fortified by Alexander Jannaeus in the first century BCE, Herod the Great captured it in the power struggle that followed the death of his father Antipater. It survived the siege of the last Hasmonean king Antigonus II Mattathias, no Hasmonean-period building remains could be identified during archaeological excavations at Masada. According to Josephus, between 37 and 31 BCE, Herod the Great built a fortress on the plateau as a refuge for himself in the event of a revolt. In 66 CE, a group of Jewish rebels, the Sicarii, after the destruction of the Second Temple in 70 CE, additional members of the Sicarii fled Jerusalem and settled on the mountaintop after slaughtering the Roman garrison. According to Josephus, the Sicarii were an extremist Jewish splinter group antagonistic to a grouping of Jews referred to as the Zealots. Josephus said that the Sicarii raided nearby Jewish villages including Ein Gedi, in 73 CE, the Roman governor of Iudaea, Lucius Flavius Silva, headed the Roman legion X Fretensis and laid siege to Masada. The Roman legion surrounded Masada, built a wall and then a siege ramp against the western face of the plateau. According to Dan Gill, geological investigations in the early 1990s confirmed earlier observations that the 114 m high assault ramp consisted mostly of a spur of bedrock. The ramp was complete in the spring of 73, after two to three months of siege, allowing the Romans to finally breach the wall of the fortress with a battering ram on April 16. The Romans employed the X Legion and a number of units and Jewish prisoners of war, totaling some 15,000. A giant siege tower with a ram was constructed and moved laboriously up the completed ramp. Originally, Jewish rebels on top of Masada threw stones at those building and constructing the ramp, to counter this tactic, the Romans put captured Jewish prisoners from previously conquered towns to work at the ramp
