Ngonye Falls
The Ngonye Falls or Sioma Falls is a waterfall on the Zambezi river in Western province Zambia, near the town of Sioma and a few hundred kilometres upstream from the Victoria Falls. Situated in the southern part of Barotseland, the falls are a day's journey from the capital, Lusaka. Their inaccessibility makes them much less known than Victoria Falls. The Ngonye Falls Community Partnership Park is located at the falls. The falls are formed by the erosion of a hard sandstone layer to form the drop. Their height is only , but the width of the falls is impressive. They form a broad crescent, interrupted by rocky outcrops. Upstream from the falls, the river is broad and shallow as it flows across Kalahari sands, but below the falls extensive white water rapids exist, as the river is hemmed in by gorge A canyon (from ; archaic British English spelling: ''cañon''), or gorge, is a deep cleft between escarpments or cliffs resulting from weathering and the erosion, erosive activit ...

Erosion
Erosion is the action of surface processes (such as water flow or wind) that removes soil, rock, or dissolved material from one location on the Earth's crust, and then transports it to another location where it is deposited. Erosion is distinct from weathering which involves no movement. Removal of rock or soil as clastic sediment is referred to as ''physical'' or ''mechanical'' erosion; this contrasts with ''chemical'' erosion, where soil or rock material is removed from an area by dissolution. Eroded sediment or solutes may be transported just a few millimetres, or for thousands of kilometres. Agents of erosion include rainfall; bedrock wear in rivers; coastal erosion by the sea and waves; glacial plucking, abrasion, and scour; areal flooding; wind abrasion; groundwater processes; and mass movement processes in steep landscapes like landslides and debris flows. The rates at which such processes act control how fast a surface is eroded. Typically, physical erosion procee ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zambezi River
The Zambezi River (also spelled Zambeze and Zambesi) is the fourth-longest river in Africa, the longest east-flowing river in Africa and the largest flowing into the Indian Ocean from Africa. Its drainage basin covers , slightly less than half of the Nile's. The river rises in Zambia and flows through eastern Angola, along the north-eastern border of Namibia and the northern border of Botswana, then along the border between Zambia and Zimbabwe to Mozambique, where it crosses the country to empty into the Indian Ocean. The Zambezi's most noted feature is Victoria Falls. Its other falls include the Chavuma Falls at the border between Zambia and Angola, and Ngonye Falls near Sioma in western Zambia. The two main sources of hydroelectric power on the river are the Kariba Dam, which provides power to Zambia and Zimbabwe, and the Cahora Bassa Dam in Mozambique, which provides power to Mozambique and South Africa. Additionally, two smaller power stations are along the Zambezi Ri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Waterfalls Of Zambia
A waterfall is a point in a river or stream where water flows over a vertical drop or a series of steep drops. Waterfalls also occur where meltwater drops over the edge of a tabular iceberg or ice shelf. Waterfalls can be formed in several ways, but the most common method of formation is that a river courses over a top layer of resistant bedrock before falling on to softer rock, which erodes faster, leading to an increasingly high fall. Waterfalls have been studied for their impact on species living in and around them. Humans have had a distinct relationship with waterfalls for years, travelling to see them, exploring and naming them. They can present formidable barriers to navigation along rivers. Waterfalls are religious sites in many cultures. Since the 18th century they have received increased attention as tourist destinations, sources of hydropower, andparticularly since the mid-20th centuryas subjects of research.

Gorge
A canyon (from ; archaic British English spelling: ''cañon''), or gorge, is a deep cleft between escarpments or cliffs resulting from weathering and the erosion, erosive activity of a river over geologic time scales. Rivers have a natural tendency to cut through underlying surfaces, eventually wearing away rock layers as sediments are removed downstream. A river bed will gradually reach a baseline elevation, which is the same elevation as the body of water into which the river drains. The processes of weathering and erosion will form canyons when the river's River source, headwaters and estuary are at significantly different elevations, particularly through regions where softer rock layers are intermingled with harder layers more resistant to weathering. A canyon may also refer to a rift between two mountain peaks, such as those in ranges including the Rocky Mountains, the Alps, the Himalayas or the Andes. Usually, a river or stream carves out such splits between mountains. Examp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
White Water Rapids
Whitewater forms in a rapid context, in particular, when a river's gradient changes enough to generate so much turbulence that air is trapped within the water. This forms an unstable current that froths, making the water appear opaque and white. The term "whitewater" also has a broader meaning, applying to any river or creek that has a significant number of rapids. The term is also used as an adjective describing boating on such rivers, such as whitewater canoeing or whitewater kayaking. Fast rivers Four factors, separately or in combination, can create rapids: gradient, constriction, obstruction, and flow rate. Gradient, constriction, and obstruction are streambed topography factors and are relatively consistent. Flow rate is dependent upon both seasonal variation in precipitation and snowmelt and upon release rates of upstream dams. Streambed topography Streambed topography is the primary factor in creating rapids, and is generally consistent over time. Increased fl ...

Kalahari
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. The only permanent river, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sandstone
Sandstone is a clastic sedimentary rock composed mainly of sand-sized (0.0625 to 2 mm) silicate grains. Sandstones comprise about 20–25% of all sedimentary rocks. Most sandstone is composed of quartz or feldspar (both silicates) because they are the most resistant minerals to weathering processes at the Earth's surface. Like uncemented sand, sandstone may be any color due to impurities within the minerals, but the most common colors are tan, brown, yellow, red, grey, pink, white, and black. Since sandstone beds often form highly visible cliffs and other topographic features, certain colors of sandstone have been strongly identified with certain regions. Rock formations that are primarily composed of sandstone usually allow the percolation of water and other fluids and are porous enough to store large quantities, making them valuable aquifers and petroleum reservoirs. Quartz-bearing sandstone can be changed into quartzite through metamorphism, usually related to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lusaka
Lusaka (; ) is the Capital city, capital and largest city of Zambia. It is one of the fastest-developing cities in southern Africa. Lusaka is in the southern part of the central plateau at an elevation of about . , the city's population was about 3.3 million, while the urban population is estimated at 2.5 million in 2018. Lusaka is the centre of both commerce and government in Zambia and connects to the country's four main highways heading Great North Road, Zambia, north, Livingstone Road, south, Great East Road, east and Great West Road, Zambia, west. English is the official language of the city administration, while Bemba language, Bemba, Tonga language (Zambia and Zimbabwe), Tonga, Lenje, Soli language, Soli, Lozi language, Lozi and Nyanja are the commonly spoken street languages. The earliest evidence of settlement in the area dates to the 6th century AD, with the first known settlement in the 11th century. It was then home to the Lenje people, Lenje and Soli language, Soli ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Day's Journey
A day's journey in pre-modern literature, including the Bible, ancient geographers and ethnographers such as Herodotus, is a measurement of distance. In the Bible, it is not as precisely defined as other Biblical measurements of distance; the distance has been estimated from . records a party of three people and two mules who traveled from Bethlehem to Gibeah, a distance of about 10 miles, in an afternoon. Porter notes that a mule can travel about 3 miles per hour, covering 24 miles in an eight-hour day. In translation by J.B. Bury (Priscus, fr. 8 in Fragmenta Historicorum Graecorum) ''We set out with the barbarians, and arrived at Sardica, which is thirteen days for a fast traveller from Constantinople.'' From Constantinople-Istanbul to Sofia is 550–720 km distance at a pace between 42 and 55 km /day. Based on a comprehensive review of references in Herodotus Herodotus ( ; grc, , }; BC) was an ancient Greek historian and geographer from the Greek city of ...

Barotseland
Barotseland ( Lozi: Mubuso Bulozi) is a region between Namibia, Angola, Botswana, Zimbabwe including half of eastern and northern provinces of Zambia and the whole of Democratic Republic of Congo's Katanga Province. It is the homeland of the Lozi people or ''Barotse'', or Malozi, who are a unified group of over 46 individual formerly diverse tribes related through kinship, whose original branch are the Luyi (Maluyi), and also assimilated Southern Sotho tribe of South Africa known as the Makololo. The Barotse speak Silozi, a language most closely related to Sesotho. Barotseland covers an area of 252,386 square kilometres, but is estimated to have been twice as large at certain points in its history. Once an empire, the Kingdom stretched into Namibia, Angola, Botswana, Zimbabwe including half of eastern and northern provinces of Zambia and the Democratic Republic of Congo's Katanga Province. Under the British colonial administration, Barotseland was a Protectorate of the Briti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
