Ngami
Lake Ngami is an endorheic lake in Botswana north of the Kalahari Desert. It is seasonally filled by the Taughe River, an effluent of the Okavango River system flowing out of the western side of the Okavango Delta. It is one of the fragmented remnants of the ancient Lake Makgadikgadi. Although the lake has shrunk dramatically beginning from 1890, it remains an important habitat for birds and wildlife, especially in flood year Lake Ngami had many famous visitors during the 19th (and into the 20th) century. In 1849 David Livingstone described it as a "shimmering lake, some long and 20 [30 km] wide". Livingstone also made a few cultural notes about the people living in this area; he noticed they had a story similar to that of the Tower of Babel, except that the builders' heads were "cracked by the fall of the scaffolding" (''Missionary Travels'', chap. 26). One of the illustrations is known to have been made on the basis of a sketch by Mr. Alfred Ryder (1825-1850) son of Artist ...

Ngami Lacuna
Ngami Lacuna is a feature on Saturn's largest moon, Titan, believed to be a currently dry bed of an intermittent hydrocarbon lake. When full, the lake would be composed of liquid methane and ethane. It was detected in 2007 by the ''Cassini–Huygens'' space probe. Ngami Lacuna is located at coordinates 66.7° N and 213.9° W on Titan's globe and is 37.2 km in diameter. It is named after Lake Ngami, in Botswana, and like its terrestrial namesake is considered to be endorheic An endorheic basin (; also spelled endoreic basin or endorreic basin) is a drainage basin that normally retains water and allows no outflow to other external bodies of water, such as rivers or oceans, but drainage converges instead into lakes ....

Okavango Delta
The Okavango Delta (or Okavango Grassland; formerly spelled "Okovango" or "Okovanggo") in Botswana is a swampy inland delta formed where the Okavango River reaches a tectonic trough at an altitude of 930–1,000 m in the central part of the endorheic basin of the Kalahari. All the water reaching the delta is ultimately evaporated and transpired and does not flow into any sea or ocean. Each year, about of water spreads over the area. Some flood waters drain into Lake Ngami. The area was once part of Lake Makgadikgadi, an ancient lake that had mostly dried up by the early Holocene. The Moremi Game Reserve, a national park, is on the eastern side of the delta. The delta was named as one of the Seven Natural Wonders of Africa, which were officially declared on 11 February 2013 in Arusha, Tanzania. On 22 June 2014, the Okavango Delta became the 1000th site to be officially inscribed on the UNESCO World Heritage List. Geography Floods The Okavango is produced by seasonal flood ...

David Livingstone
David Livingstone (; 19 March 1813 – 1 May 1873) was a Scottish physician, Congregationalist, and pioneer Christian missionary with the London Missionary Society, an explorer in Africa, and one of the most popular British heroes of the late 19th-century Victorian era. David was the husband of Mary Moffat Livingstone, from the prominent 18th Century missionary family, Moffat. He had a mythic status that operated on a number of interconnected levels: Protestant missionary martyr, working-class "rags-to-riches" inspirational story, scientific investigator and explorer, imperial reformer, anti-slavery crusader, and advocate of British commercial and colonial expansion. Livingstone's fame as an explorer and his obsession with learning the sources of the Nile River was founded on the belief that if he could solve that age-old mystery, his fame would give him the influence to end the East African Arab–Swahili slave trade. "The Nile sources", he told a friend, "are valuabl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Botswana
Botswana (, ), officially the Republic of Botswana ( tn, Lefatshe la Botswana, label=Setswana, ), is a landlocked country in Southern Africa. Botswana is topographically flat, with approximately 70 percent of its territory being the Kalahari Desert. It is bordered by South Africa to the south and southeast, Namibia to the west and north, and Zimbabwe to the northeast. It is connected to Zambia across the short Zambezi River border by the Kazungula Bridge. A country of slightly over 2.3 million people, Botswana is one of the most sparsely populated countries in the world. About 11.6 percent of the population lives in the capital and largest city, Gaborone. Formerly one of the world's poorest countries—with a GDP per capita of about US$70 per year in the late 1960s—it has since transformed itself into an upper-middle-income country, with one of the world's fastest-growing economies. Modern-day humans first inhabited the country over 200,000 years ago. The Tswana ethnic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endorheic
An endorheic basin (; also spelled endoreic basin or endorreic basin) is a drainage basin that normally retains water and allows no outflow to other external bodies of water, such as rivers or oceans, but drainage converges instead into lakes or swamps, permanent or seasonal, that equilibrate through evaporation. They are also called closed or terminal basins, internal drainage systems, or simply basins. Endorheic regions contrast with open and closed lakes, exorheic regions. Endorheic water bodies include some of the largest lakes in the world, such as the Caspian Sea, the world's largest inland body of water. Basins with subsurface outflows which eventually lead to the ocean are generally not considered endorheic; they are cryptorheic. Endorheic basins constitute local base levels, defining a limit of erosion and deposition processes of nearby areas. Etymology The term was borrowed from French ''endor(rh)éisme'', coined from the combining form ''endo-'' (from grc, ἔν ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Okavango River
The Okavango River (formerly spelled Okovango or Okovanggo), Also known as the Cubango River, is a river in southwest Africa. It is the fourth-longest river system in southern Africa, running southeastward for . It begins at an elevation of in the sandy highlands of Angola. Farther south, it forms part of the border between Angola and Namibia, and then flows into Botswana. The Okavango does not have an outlet to the sea. Instead, it discharges into the Okavango Delta or Okavango Alluvial Fan, in an endorheic basin in the Kalahari Desert. Flow In Angola, the upper reaches of the Cuito (a tributary river to the Okavango) suffers clogging due to controlled burns of the vegetation, reducing water flow downstream as the accumulated water instead flows into the sand. Before it enters Botswana, the river drops 4 m in a series of rapids known as Popa Falls, visible when the river is low, as during the dry season. In the rainy season, an outflow to the Boteti River in turn seaso ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lake Makgadikgadi
Lake Makgadikgadi ( tn, Letsha la Makgadikgadi, label=Setswana, ) was a paleolake that existed in what is now the Kalahari Desert in Botswana from 2,000,000 years BP to 10,000 years BP. It may have once covered an area of from and was 30 m deep. The Okavango, Upper Zambezi, and Cuando rivers once all emptied into the lake. Its remains are seen in the Makgadikgadi salt pans, one of the largest salt pans in the world. DNA research suggests the lake region is the homeland of ''Homo sapiens'', where humans first evolved as a distinct species about 200,000 years ago, before expanding to other parts of Africa about 70,000 years later. Origin and history Approximately 3 million years ago, strong easterly winds formed long dunes, which ran from east to west across the middle of the Kalahari Desert. During wetter times, these dunes channeled the great rivers of the area, the Okavango, Chobe, and Upper Zambezi, southeastward to join with the Limpopo River and drain into the Ind ...

Tower Of Babel
The Tower of Babel ( he, , ''Mīgdal Bāḇel'') narrative in Genesis 11:1–9 is an origin myth meant to explain why the world's peoples speak different languages. According to the story, a united human race speaking a single language and migrating eastward, comes to the land of Shinar (). There they agree to build a city and a tower with its top in the sky. Yahweh, observing their city and tower, confounds their speech so that they can no longer understand each other, and scatters them around the world. Some modern scholars have associated the Tower of Babel with known structures, notably the Etemenanki, a ziggurat dedicated to the Mesopotamian god Marduk in Babylon. A Sumerian story with some similar elements is told in ''Enmerkar and the Lord of Aratta''. Narrative Etymology The phrase "Tower of Babel" does not appear in the Bible; it is always "the city and the tower" () or just "the city" (). The original derivation of the name Babel (also the Hebrew name for B ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
