Africa’s Physical Geography


Plateau and basins

Plateau and Basins

  • Most of Africa is elevated 1,000 feetabove sea level. A plateau covers most of the continent causing this rise.

  • Basins are depressions, or dips, in the plateau.


Rivers

Rivers

  • Niger – Located in West Africa. It is 2,600 miles long.

  • Congo – Located in Central Africa. It is 2,900 miles long.

  • Nile – Located in North Africa. It is 4,160 miles long. It is the longest river in the world.


Aswan high dam

Aswan High Dam

  • Nile goes through flood and drought seasons. The Aswan High Dam was built to help the farmers with irregular water supply. It’s construction created a false lake. It has disrupted the successful Nile cycle.


Mountains

Mountains

  • Ahaggar Mountains – North Africa

  • Tibesti Mountains – North Africa

  • Atlas Mountains – North Africa

  • Mt. Cameroon – over 13,000 ft. in Central Africa

  • Mt. Kenya – over 17,000 ft. in East Africa

  • Mt. Kilimanjaro – over 19,000 ft. in East Africa. It is the tallest mountain in Africa.


Deserts

Deserts

  • Kalahari Desert – Southern Africa, approximately 100,000 square miles in size

  • Namib Desert – Southern Africa, slightly larger than the Kalahari. It is located to the West of the Kalahari.

  • Sahara Desert – North Africa. It is the largest desert in the world at 3,500,000 square miles and growing.


Forests

Forests

  • Africa has the largest tropical land area of any continent, because it sits on the equator.

  • The largest rainforest is in Central Africa.

    It is mostly in the Congo Basin.

  • The canopy is where most animals in a

    rainforest live. It is the top layer of

    branches, approximately 150 ft. high.

  • Slash-and-burn farming has nearly wiped out Madagascar’s rain forest.

  • Oak and pine forests grow near the Atlas Mountains


Rift valleys

Rift Valleys

  • Long thin valleys formed by tectonic activity. East Africa is leaving the rest of Africa. Africa’s rift valleys are over 4,000 miles long.

  • Lake Tanganyika – is the longest freshwater lake in the world. It is a result of the rift valleys.

  • Lake Victoria – Africa’s largest lake. Also a result of the rift valleys. World’s 2nd largest freshwater lake.

  • Victoria Falls – It’s spray can be seen from 50 miles away. It is the largest waterfall in the world.


Plains

Plains

  • Serengeti – is a grassland. Some of the grasses grow taller than the average person. It is in East Africa.

  • Serengeti National Park – protects an area and allows for tourism.

  • Sahel – means “shore of the desert”. It is a narrow bit of grassland by the Sahara. It is mostly in West Africa.

    • Desertification – the expansion of the desert into moist areas near the desert


Resources

Resources

  • Mineral – World’s largest producer of chromium. Africa also has a lot of gold, platinum, cobalt, copper, phosphates, diamonds, and various other minerals.

  • World’s leader in Petroleum production. Nigeria has a lot of debt from mismanagement of their large oil supply.

  • World’s largest producer of cocoa beans.

  • Agriculture is the primary economic activity in Africa.
