Lake Lisan
Lake Lisan was a prehistoric lake that existed between 70,000 and 12,000 BP in the Jordan Rift Valley in the Near East. It is sometimes referred to as a Pleistocene lake. Lisan means ''tongue'' in Arabic relating to the shape of the Lisan Peninsula where studies of the sediment formations were taken. The sediment formations left by the lake extend from Lake Tiberias (the Sea of Galilee) in the north to a boundary ridge ca. 35 km south of the Dead Sea. The lake left behind a layer of lacustrine sediment that blankets the Jordan Valley with terraces of sediment up to 40 m thick. These sediments are commonly called marls and are composed of layers of true loam and calcareous silt loams mixed with other chemicals and salts. At its height, the lake covered several other basins in the area with a maximum area of ca. 2000 km2, a length of 200 km and a width of no more than 17 km. The formations were named the ''Lisan deposits'' and first described by Lartet in 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Silt
Silt is granular material of a size between sand and clay and composed mostly of broken grains of quartz. Silt may occur as a soil (often mixed with sand or clay) or as sediment mixed in suspension with water. Silt usually has a floury feel when dry, and lacks plasticity when wet. Silt also can be felt by the tongue as granular when placed on the front teeth (even when mixed with clay particles). Silt is a common material, making up 45% of average modern mud. It is found in many river deltas and as wind-deposited accumulations, particularly in central Asia, north China, and North America. It is produced in both very hot climates (through such processes as collisions of quartz grains in dust storms) and very cold climates (through such processes as glacial grinding of quartz grains.) Loess is soil rich in silt which makes up some of the most fertile agricultural land on Earth. However, silt is very vulnerable to erosion, and it has poor mechanical properties, making construction ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Natufian
The Natufian culture () is a Late Epipaleolithic archaeological culture of the Levant, dating to around 15,000 to 11,500 years ago. The culture was unusual in that it supported a sedentary or semi-sedentary population even before the introduction of agriculture. The Natufian communities may be the ancestors of the builders of the first Neolithic settlements of the region, which may have been the earliest in the world. Some evidence suggests deliberate cultivation of cereals, specifically rye, by the Natufian culture, at Tell Abu Hureyra, the site of earliest evidence of agriculture in the world. The world's oldest known evidence of the production of bread-like foodstuff has been found at Shubayqa 1, a 14,400-year-old site in Jordan's northeastern desert, 4,000 years before the emergence of agriculture in Southwest Asia In addition, the oldest known evidence of possible beer-brewing, dating to approximately 13,000 BP, was found at the Raqefet Cave in Mount Carmel near Haifa in I ...

Kebaran
The Kebaran culture, also known as the Early Epipalaeolithic Near East, Near East Epipalaeolithic, was an archaeological culture in the Eastern Mediterranean area (c. 23,000 to 15,000 BP), named after its type site, Kebara Cave south of Haifa. The Kebaran were a highly mobile nomadic population, composed of hunters and gatherers in the Levant and Sinai Peninsula, Sinai areas who used microliths, microlithic tools. Overview The Kebaran is the last Upper Paleolithic phase of the Levant. Kebaran stone tool Assemblage (archaeology), assemblages are characterized by small, geometric microliths, and are thought to have lacked the specialized grinders and pounders found in later Near Eastern cultures. Small stone tools called microliths and retouched bladelets can be found for the first time. The microliths of this culture period differ greatly from the Aurignacian artifacts. The Kebaran is preceded by the Athlitian phase of the Upper Paleolithic Levantine Aurignacian (formerly called A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bronze Age
The Bronze Age is a historic period, lasting approximately from 3300 BC to 1200 BC, characterized by the use of bronze, the presence of writing in some areas, and other early features of urban civilization. The Bronze Age is the second principal period of the three-age system proposed in 1836 by Christian Jürgensen Thomsen for classifying and studying ancient societies and history. An ancient civilization is deemed to be part of the Bronze Age because it either produced bronze by smelting its own copper and alloying it with tin, arsenic, or other metals, or traded other items for bronze from production areas elsewhere. Bronze is harder and more durable than the other metals available at the time, allowing Bronze Age civilizations to gain a technological advantage. While terrestrial iron is naturally abundant, the higher temperature required for smelting, , in addition to the greater difficulty of working with the metal, placed it out of reach of common use until the end o ...

Beit She'an
Beit She'an ( he, בֵּית שְׁאָן '), also Beth-shean, formerly Beisan ( ar, بيسان ), is a town in the Northern District (Israel), Northern District of Israel. The town lies at the Beit She'an Valley about 120 m (394 feet) below sea level. Beit She'an is believed to be one of the oldest cities in the region. It has played an important role in history due to its geographical location at the junction of the Jordan River, Jordan River Valley and the Jezreel Valley. The town's ancient tell contains remains beginning in the Chalcolithic, Chalcolithic period. It served as an New Kingdom of Egypt, Egyptian administrative center during the Late Bronze Age. During the Hellenistic period, the settlement was known as Scythopolis (Ancient Greek: ''Σκυθόπολις''). After the region came under Roman Empire, Roman rule, Scythopolis gained imperial free status and was the leading city of the Decapolis. Later, under Byzantine rule, it served as the capital of Palaestina Sec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lake Beisan
Lake Beisan was a prehistoric lake that existed from ca. 12,000 to 5,000 BC in the north of the Jordan Valley in the Near East near modern-day Beit She'an. This freshwater lake reached its highest level of 100 metres below sea level in the Upper Paleolithic around 12,000 BC, when it extended from near the Sea of Gallilee (aka Lake Tiberias) in the north to Wadi Yabis and Wadi Malih in the south. It occupied the northern basin of the former Lake Lisan, "long after the retreat of the earlier lake" (which ended about 16-15 ka). It was first noticed by Dr. Leo Picard in a publication of 1929 who noticed higher altitude lake beds and eroded rock structures and named the lake after a notable ancient town in the area. David Neev conducted stratigraphic analysis in 1967 to provide further evidence from a sequence of sediments left by the lake. Archaeological evidence supports the geological with no Epipaleolithic sites on the western side of the Beisan Basin below 100 metres below sea l ...

Holocene
The Holocene ( ) is the current geological epoch. It began approximately 11,650 cal years Before Present (), after the Last Glacial Period, which concluded with the Holocene glacial retreat. The Holocene and the preceding Pleistocene together form the Quaternary period. The Holocene has been identified with the current warm period, known as MIS 1. It is considered by some to be an interglacial period within the Pleistocene Epoch, called the Flandrian interglacial.Oxford University Press – Why Geography Matters: More Than Ever (book) – "Holocene Humanity" section https://books.google.com/books?id=7P0_sWIcBNsC The Holocene corresponds with the rapid proliferation, growth and impacts of the human species worldwide, including all of its written history, technological revolutions, development of major civilizations, and overall significant transition towards urban living in the present. The human impact on modern-era Earth and its ecosystems may be considered of global si ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Precipitation (meteorology)
In meteorology, precipitation is any product of the condensation of atmospheric water vapor that falls under gravitational pull from clouds. The main forms of precipitation include drizzle, rain, sleet, snow, ice pellets, graupel and hail. Precipitation occurs when a portion of the atmosphere becomes saturated with water vapor (reaching 100% relative humidity), so that the water condenses and "precipitates" or falls. Thus, fog and mist are not precipitation but colloids, because the water vapor does not condense sufficiently to precipitate. Two processes, possibly acting together, can lead to air becoming saturated: cooling the air or adding water vapor to the air. 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 condense ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Europe
Europe is a large peninsula conventionally considered a continent in its own right because of its great physical size and the weight of its history and traditions. Europe is also considered a Continent#Subcontinents, subcontinent of Eurasia and it is located entirely in the Northern Hemisphere and mostly in the Eastern Hemisphere. Comprising the westernmost peninsulas of Eurasia, it shares the continental landmass of Afro-Eurasia with both Africa and Asia. It is bordered by the Arctic Ocean to the north, the Atlantic Ocean to the west, the Mediterranean Sea to the south and Asia to the east. Europe is commonly considered to be Boundaries between the continents of Earth#Asia and Europe, separated from Asia by the drainage divide, watershed of the Ural Mountains, the Ural (river), Ural River, the Caspian Sea, the Greater Caucasus, the Black Sea and the waterways of the Turkish Straits.

Levant
The Levant () is an approximate historical geographical term referring to a large area in the Eastern Mediterranean region of Western Asia. In its narrowest sense, which is in use today in archaeology and other cultural contexts, it is equivalent to a stretch of land bordering the Mediterranean in South-western Asia,Gasiorowski, Mark (2016). ''The Government and Politics of the Middle East and North Africa''. }, ), meaning "the eastern place, where the Sun rises". In the 13th and 14th centuries, the term ''levante'' was used for Italian maritime commerce in the Eastern Mediterranean, including Greece, Anatolia, Syria-Palestine, and Egypt, that is, the lands east of Venice. Eventually the term was restricted to the Muslim countries of Syria-Palestine and Egypt. In 1581, England set up the Levant Company to monopolize commerce with the Ottoman Empire. The name ''Levant States'' was used to refer to the French mandate over Syria and Lebanon after World War I. This is probab ...
