Which of these rivers primarily flows in South Africa?

  1. A.Orange River
  2. B.Nile River
  3. C.Congo River
  4. D.Niger River

Correct answer

A. Orange River

Explanation

The correct answer is A, Orange River. The Orange River is the longest river of South Africa, about 2,200 km long. It rises in the Drakensberg mountains of Lesotho, flows west across South Africa and falls into the Atlantic Ocean at Alexander Bay. For part of its course it forms the border between South Africa and Namibia. Its main tributary is the Vaal, and the Augrabies Falls lie on the Orange. The Limpopo is the other big river of South Africa, flowing east into the Indian Ocean. B is wrong because the Nile, the longest river in the world, flows north through countries such as Uganda, Sudan and Egypt into the Mediterranean Sea. C is wrong because the Congo flows through Central Africa, crosses the Equator twice and enters the Atlantic. D is wrong because the Niger flows through West Africa (Guinea, Mali, Niger and Nigeria) into the Gulf of Guinea. Exam tip: South Africa = Orange and Limpopo; Nile = north-east Africa; Congo = crosses the Equator twice; Niger = West Africa; Zambezi = Victoria Falls.

  2. B.1 and 3 only
  3. C.2 and 3 only
  4. D.1, 2 and 3
Show answer
Correct answer: C. 2 and 3 only

Himalayan rivers are perennial, so statement 1 is wrong, while statements 2 and 3 are correct. Himalayan rivers such as the Ganga, Indus and Brahmaputra rise from glaciers and snowfields and also get monsoon rain, so they flow all year round, including in winter.

All three statements about latitude are true. Latitude decides how directly the Sun's rays strike a place, so temperature, rainfall and the type of vegetation change from the equator towards the poles, from hot, wet rainforests to cold tundra.
