PHYSICAL MAP OF THE CONTINENTS:AFRICA

Africa is the thrid largest continent, with a surface of more than 30 million square kilometres or a 20% of the Earh's surface.

Continental relief.

About a 50% of the African relief is occupied by plateaus and a few plains. 
We can distinguish several types of landforms in the african relief:
  • Old massifs inside the plateaus: Ahaggar Mountains, Tibesti Mountains and Marrah Mountains.
Ahaggar mountains.

  • Depressions: Niger Basin, Chad Basin, Congo Basin.
  • Mountain ranges: Atlas Mountains and Drakensberg Mountains.
  • The Rift Valley a huge fracture of volcanic origin which include depressions fill with water and volcanoes such as mounts Kenya and Kilimanajaro.

Seas, lakes and rivers.

There are several lakes of two types:
  • located in basins (Victoria, Chad).
  • located in fractures in the terrain (Albert, Tanganyka and Malawi).

African rivers are very long and carry a high volume of water. The main rivers are: the Nile (the longest river in the world with 6.670 km), the Niger, the Congo, the Zambezi and Orange.


About the coast the main feature are:
  • Islands: Madagascar.
  • Peninsulas: Somalia.
  • Gulfs: Gabes, Guinea and Benguela.
  • Capes: Good Hope, Aguilhas and Guardafui.
