List Of The Physiographic Regions Of The World
The landforms of Earth are generally divided into physiographic divisions Physical geography (also known as physiography) is one of the three main branches of geography. Physical geography is the branch of natural science which deals with the processes and patterns in the natural environment such as the atmosphere, ..., consisting of physiographic provinces, which in turn consist of physiographic sections, though some others use different terminology, such as realms, regions and subregions. Some areas have further categorized their respective areas into more detailed subsections.

Landform
A landform is a natural or anthropogenic land feature on the solid surface of the Earth or other planetary body. Landforms together make up a given terrain, and their arrangement in the landscape is known as topography. Landforms include hills, mountains, canyons, and valleys, as well as shoreline features such as bays, peninsulas, and seas, including submerged features such as mid-ocean ridges, volcanoes, and the great ocean basins. Physical characteristics Landforms are categorized by characteristic physical attributes such as elevation, slope, orientation, stratification, rock exposure and soil type. Gross physical features or landforms include intuitive elements such as berms, mounds, hills, ridges, cliffs, valleys, rivers, peninsulas, volcanoes, and numerous other structural and size-scaled (e.g. ponds vs. lakes, hills vs. mountains) elements including various kinds of inland and oceanic waterbodies and sub-surface features. Mountains, hills, plateaux, and plains are t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chad Basin
The Chad Basin is the largest endorheic basin in Africa, centered on Lake Chad. It has no outlet to the sea and contains large areas of semi-arid desert and savanna. The drainage basin is roughly coterminous with the sedimentary basin of the same name, but extends further to the northeast and east. The basin spans eight countries, including most of Chad and a large part of Niger. The region has an ethnically diverse population of about 30 million people as of 2011, growing rapidly. A combination of dams, increased irrigation, climate change, and reduced rainfall are causing water shortages, contributing to terrorism and the rise of Boko Haram in the region. Lake Chad continues to shrink. Geology The geological basin, which is smaller than the drainage basin, is a Phanerozoic sedimentary basin formed during the plate divergence that opened the South Atlantic Ocean. The basin lies between the West African Craton and Congo Craton, and formed around the same time as the Benue Tr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Karoo
The Karoo ( ; from the Afrikaans borrowing of the South Khoekhoe !Orakobab or Khoemana word ''ǃ’Aukarob'' "Hardveld") is a semi-desert natural region of South Africa. No exact definition of what constitutes the Karoo is available, so its extent is also not precisely defined. The Karoo is partly defined by its topography, geology and climate, and above all, its low rainfall, arid air, cloudless skies, and extremes of heat and cold.Potgieter, D.J. & du Plessis, T.C. (1972) ''Standard Encyclopaedia of Southern Africa''. Vol. 6. pp. 306–307. Nasou, Cape Town.''Reader’s Digest Illustrated Guide to Southern Africa''. (5th Ed. 1993). pp. 78–89. Reader’s Digest Association of South Africa Pty. Ltd., Cape Town. The Karoo also hosted a well-preserved ecosystem hundreds of million years ago which is now represented by many fossils. The ǃ’Aukarob formed an almost impenetrable barrier to the interior from Cape Town, and the early adventurers, explorers, hunters, and travelers o ...

Veld
Veld ( or ), also spelled veldt, is a type of wide open rural landscape in :Southern Africa. Particularly, it is a flat area covered in grass or low scrub, especially in the countries of South Africa, Lesotho, Eswatini, Zimbabwe and Botswana. A certain sub-tropical woodland ecoregion of Southern Africa has been officially defined as the Bushveld by the World Wide Fund for Nature. Trees are not abundant—frost, fire and grazing animals allow grass to grow but prevent the build-up of dense foliage. Etymology The word ''veld'' () comes from the Afrikaans word for "field". The etymological origin is older modern Dutch ''veldt'', a spelling that the Dutch abandoned in favour of ''veld'' during the 19th century, decades before the first Afrikaans dictionary.Eric Anderson Walker (ed). The Cambridge History of the British Empire, Volume 4. Cambridge University Press 1963 (Afrikaans: pp. 890–894) A cognate to the English ''field'', it was spelt ''velt'' in Middle Dutch and ' ...

Kalahari Region
The Kalahari Desert is a large semi-arid sandy savanna in Southern Africa extending for , covering much of Botswana, and parts of Namibia and South Africa. It is not to be confused with the Angolan, Namibian, and South African Namib coastal desert, whose name is of Khoekhoegowab origin and means "vast place". Etymology ''Kalahari'' is derived from the Tswana word ''Kgala'', meaning "the great thirst", or ''Kgalagadi'', meaning "a waterless place"; the Kalahari has vast areas covered by red sand without any permanent surface water. History The Kalahari Desert was not always a dry desert. The fossil flora and fauna from Gcwihaba Cave in Botswana indicates that the region was much wetter and cooler at least from 30 to 11 thousand BP (before present) especially after 17,500 BP. Geography Drainage of the desert is by dry black valleys, seasonally inundated pans and the large salt pans of the Makgadikgadi Pan in Botswana and Etosha Pan in Namibia.

Congo Basin
The Congo Basin (french: Bassin du Congo) is the sedimentary basin of the Congo River. The Congo Basin is located in Central Africa, in a region known as west equatorial Africa. The Congo Basin region is sometimes known simply as the Congo. It contains some of the largest tropical rainforests in the world and is an important source of water used in agriculture and energy generation. The rainforest in the Congo Basin is the largest rainforest in Africa and second only to the Amazon rainforest in size, with 300 million hectares compared to the 800 million hectares in the Amazon. Because of its size and diversity, many experts have characterized the basin's forest as important for mitigating climate change because of its role as a carbon sink. However, deforestation and degradation of the ecology by the impacts of climate change may increase stress on the forest ecosystem, in turn making the hydrology of the basin more variable. A 2012 study found that the variability in precipita ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
South Guinea Highlands
South is one of the cardinal directions or compass points. The direction is the opposite of north and is perpendicular to both east and west. Etymology The word ''south'' comes from Old English ''sūþ'', from earlier Proto-Germanic ''*sunþaz'' ("south"), possibly related to the same Proto-Indo-European root that the word ''sun'' derived from. Some languages describe south in the same way, from the fact that it is the direction of the sun at noon (in the Northern Hemisphere), like Latin meridies 'noon, south' (from medius 'middle' + dies 'day', cf English meridional), while others describe south as the right-hand side of the rising sun, like Biblical Hebrew תֵּימָן teiman 'south' from יָמִין yamin 'right', Aramaic תַּימנַא taymna from יָמִין yamin 'right' and Syriac ܬܰܝܡܢܳܐ taymna from ܝܰܡܝܺܢܳܐ yamina (hence the name of Yemen, the land to the south/right of the Levant).

Ubangi-Shari Upland
Ubangi-Shari (french: Oubangui-Chari) was a French colony in central Africa, a part of French Equatorial Africa. It was named after the Ubangi and Chari rivers along which it was colonised. It was established on 29 December 1903, from the Upper Ubangi (') and Upper Shari (') territories of the French Congo; renamed the Central African Republic (CAR) on 1 December 1958; and received independence on 13 August 1960.''World Statesmen''.Central African Republic" Accessed 29 Mar 2014. History French activity in the area began in 1889 with the establishment of the outpost Bangi at the head of navigation on the Ubangi. The Upper Ubangi was established as part of the French Congo on 9 December 1891. Despite a France-Congo Free State convention establishing a border around the 4th parallel, the area was contested from 1892 to 1895 with the Congo Free State, which claimed the region as its territory of Ubangi-Bomu ('). The Upper Ubangi was a separate colony from 13 July 1894, u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
