The Tswana are a Bantu ethnic group native to Southern Africa. Ethnic Tswana made up approximately 85% of the population of Botswana in 2011.
The Witwatersrand is a 56-kilometre-long (35 mi), north-facing scarp in South Africa. It consists of a hard, erosion-resistant quartzite metamorphic rock, over which several north-flowing rivers form waterfalls, which account for the name Witwatersrand, meaning 'white water ridge' in Afrikaans. This east-west-running scarp can be traced with only one short gap, from Bedfordview in the east, through Johannesburg and Roodepoort, to Krugersdorp in the west.
The Richat Structure, or Guelb er Richât, is a prominent circular geological feature in the Adrar Plateau of the Sahara. It is located near Ouadane in the Adrar Region of Mauritania. In Hassaniya Arabic, rīšāt means feathers and it is also known locally in Arabic as tagense, referring to the circular opening of the leather pouch that is used to draw water from local wells.
Ladysmith is a city in the Uthukela District of KwaZulu-Natal, South Africa. It lies 230 kilometres (140 mi) north-west of Durban and 365 kilometres (227 mi) south-east of Johannesburg. Important industries in the area include food processing, textiles, and tyre production. Ladysmith is the seat for both the Alfred Duma Local Municipality and Uthukela District Municipality.
The Sudbury Basin, also known as Sudbury Structure or the Sudbury Nickel Irruptive, is a major geological structure in Ontario, Canada. It is the third-largest known impact structure on Earth, as well as one of the oldest. The structure, the eroded remnant of an impact crater, was formed by the impact of an asteroid 1.849 billion years ago in the Paleoproterozoic era.
The Araguainha crater or Araguainha dome is an impact crater on the border of Mato Grosso and Goiás states, Brazil, between the villages of Araguainha and Ponte Branca. With a diameter of 40 kilometres (25 mi), it is the largest known impact crater in South America.
Roter Kamm is a meteorite crater, located in the Sperrgebiet, within the Namibian section of the Namib Desert, approximately 80 kilometres (50 mi) north of Oranjemund and 12 kilometres (7.5 mi) southwest of Aurus Mountain in the ǁKaras Region. The crater is 2.5 kilometres (1.6 mi) in diameter and is 130 metres (430 ft) deep. The age is estimated at 4.81 ± 0.5 Ma, placing it in the Pliocene. The crater is exposed at the surface, but its original floor is covered by sand deposits at least 100 metres (330 ft) thick.
The Vredefort impact structure is the largest verified impact structure on Earth. The crater, which has since been eroded away, has been estimated at 170–300 kilometres (110–190 mi) across when it was formed. The remaining structure, comprising the deformed underlying bedrock, is located in present-day Free State province of South Africa. It is named after the town of Vredefort, which is near its centre. The structure's central uplift is known as the Vredefort Dome. The impact structure was formed during the Paleoproterozoic Era, 2.023 billion years ago. It is the second-oldest known impact structure on Earth, after Yarrabubba.
Klerksdorp is located in the North West Province, South Africa. Klerksdorp is located 165 km (103 mi) southeast of Mahikeng, the provincial capital. Klerksdorp was also the first capital of the then Transvaal Republic and used to be the home of the first Stock Exchange in the region. It became an important trading town linking Kimberley to Johannesburg. It became home to a mix of farmers, miners and immigrants servicing the two industries.It was then located there because of availability of water and climate change
The Manson impact structure is an impact structure near the site of Manson, Iowa where an asteroid or comet nucleus struck the Earth during the Cretaceous Period, approximately 74 Ma. It was one of the largest known impact events to have happened in North America. Previously it was thought to have led to the extinction of the dinosaurs until isotopic ages proved that it was too old.
Lindley is a small town situated on the banks of the Vals River in the eastern region of the Free State province of South Africa. It was named after an American missionary, Daniel Lindley, who was the first ordained minister to the Voortrekkers in Natal. Basotho call it Ntha, after the river.
Bothaville is a maize farming town situated near the Vaal River in the Lejweleputswa DM of the Free State province, South Africa. It is situated 60 km east of the Vaal, on the bank of its Vals River tributary. Bothaville and the adjacent Kgotsong township have a total of approximately 46,000 residents.
Belfast is a small town in Mpumalanga Province, South Africa. It is situated in the eMakhazeni Local Municipality in the Nkangala District Municipality.
White River is a small holiday and farming town situated just north of Mbombela in Mpumalanga, South Africa. The farms in the region produce tropical fruits, macadamia nuts, vegetables, flowers and timber. As of 2011, White River had a population of 16,639.
The Battle of Dimawe was fought between several Batswana tribes and the Boers in August 1852. Under the command of Kgosi Setshele I of the Bakwena tribe, the Batswana were victorious at Dimawe Hill.
The Bangui magnetic anomaly is a local variation in the Earth's magnetic field centered at Bangui, the capital of the Central African Republic. The magnetic anomaly is roughly elliptical, about 700 km × 1,000 km, and covers most of the country, making it one of the "largest and most intense crustal magnetic anomalies on the African continent". The anomaly was discovered in the late 1950s, explored in the 1970s, and named in 1982. Its origin remains unclear.
Hargraves is a Hesperian-age complex double-layered ejecta impact crater on Mars. It was emplaced near the crustal dichotomy in the vicinity of the Nili Fossae, the Syrtis Major volcanic plains, and the Isidis impact basin, and is situated within the Syrtis Major quadrangle. Hargraves has been the target of focused study because its ejecta apron is particularly well-preserved for a Martian crater of its size. It has been analogized to similar double-layered ejecta blankets on Earth, including that of the Ries impact structure, which was where the conceptual model for how such craters formed was first advanced.
The Maniitsoq structure is a proposed 3 billion-year-old impact structure located in the Akia terrane of the North Atlantic Craton, centred about 55 km (34 mi) south-east of the town of Maniitsoq, Greenland, at 65°15′N51°50′W. Its origin has been debated since it was first proposed as an impact structure in 2012. The Maniitsoq structure is not recognised as an impact structure by the Earth Impact Database.
