Overview
Africa is the second-largest continent by land area and the second-most populous continent. It lies between the Atlantic Ocean to the west, the Indian Ocean to the east and the Mediterranean Sea to the north. The Red Sea separates much of Africa from the Arabian Peninsula.
The Equator crosses Africa, giving the continent an enormous range of climates and ecosystems. Africa contains deserts, tropical rainforests, savannas, mountains, highlands, wetlands and extensive coastlines.
Africa is also one of the most geographically diverse regions on Earth and is of fundamental importance to the study of human evolution.

Climate
Africa contains a remarkable range of climates. Because the Equator passes through the continent, climatic zones are broadly distributed around the tropical centre, although altitude, ocean currents and atmospheric circulation create substantial regional differences.
Equatorial climate
Equatorial regions experience high temperatures and substantial rainfall throughout much of the year. The Congo Basin is a major example.
Tropical savanna
Large areas of Africa are covered by savanna ecosystems characterised by seasonal rainfall and a pronounced dry season.
Desert climate
The Sahara dominates northern Africa, while the Namib and Kalahari regions are major dry environments in the south.
Mediterranean climate
Parts of northern Africa and the far southwest of the continent experience Mediterranean-type climates, with relatively dry summers and wetter winters.
Rivers and Lakes
Africa contains some of the world's most important rivers and freshwater lakes. These water systems support ecosystems, agriculture, transport, cities and human populations.
| River or Lake | Importance |
|---|---|
| Nile | Major river system of northeastern Africa and historically central to Egyptian civilisation. |
| Congo | Major river system draining the Congo Basin. |
| Niger | Important river of West Africa. |
| Zambezi | Major southern African river containing Victoria Falls. |
| Lake Victoria | One of Africa's largest lakes and an important part of the Nile drainage system. |
| Lake Tanganyika | One of the world's deepest freshwater lakes. |
| Lake Malawi | Large East African lake known for exceptional freshwater biodiversity. |
The Sahara Desert
The Sahara is the world's largest hot desert. It extends across much of northern Africa and covers an enormous area between the Atlantic Ocean and the Red Sea.
The landscape includes sand seas, rocky plateaus, mountains, gravel plains and isolated oases. Although the Sahara is extremely dry, it supports specially adapted plants and animals as well as human communities.
The Congo Rainforest
The Congo Basin contains the second-largest tropical rainforest system in the world after the Amazon. It covers a vast area of Central Africa and contains exceptionally important biodiversity.
The rainforest plays an important role in the regional climate and carbon cycle and provides habitat for numerous species.
African Wildlife
Africa is famous for its extraordinary diversity of large mammals, birds, reptiles, amphibians, insects and plants.
Iconic mammals
- African elephant
- African lion
- African leopard
- Black rhinoceros
- White rhinoceros
- African buffalo
