Africa: The Shape of the Land Quick Facts • Second largest continent – Largest Asia – 3 times the size of US • More independent nations than any continent on earth – 55 Location • Centrally located on Earth’s Surface • Straddles Equator – Extends thousands of miles North and South of it • Bordered by: – Between 2 Oceans • Atlantic (West) and Indian (East) – 2 Seas to its North • Mediterranean Sea (North) Red Sea (North East – Water bodies link Africa with the rest of the world • In Ancient Times these waters helped transfer people, goods, and ideas between Africa, the Middle East, and Europe. • Today they place it in the center of world transportation routes. Regions • • • • • Many distinct regions exist in Africa Geographic features give each its own identity Variety exists within regions Regional differences create cultural diversity Main Regions: – North Africa- closely linked to Middle East and Europe – The rest are referred to often as Sub-Saharan Africa • West Africa • East Africa • Central Africa • Southern Africa Landforms • Most of Africa is a vast Plateau • Mountain Ranges exist on the Edges of the Continent – Atlas Mountains- Northwest – Drakensberg Mountains- Southeast • Narrow Plains along the Coast • Plateaus – Lie at many different elevations • Highest in East and South – Continent tilts gradually downward towards west and north. – Large basins, swamps, and lakes are scattered across the plateaus. – Land drops sharply as you move from the plateaus toward the coast. – Escarpments- steep cliffs divided plateaus from coastal plains in some places. – Changes in elevation effect the course of African Rivers • Often contain a series of cataracts- large waterfalls and rapids due to elevation change. – Africans have migrated across the plateaus over thousands of years – Traders followed well traveled routes across the continent – Early Europeans were discouraged from exploring the continent because of the blockage by cataracts. • Great Rift Valley – Slices through the Eastern part of the continent – A giant fault or break in the Earth’s crust – Runs from Red sea to Zambezi River – Creates a series of mountains and valleys formed millions of years ago. – Flanked by high cliff-like walls • Rich soils have washed down from these highlands over centuries – Creates some of Africa’s Most fertile farmland – Rich in minerals and metals, but mining and transportation is difficult – May be the site of human origin Rivers • Provide fish, water for irrigation, and a source of transportation • Used today for Hydroelectric power to provide cities with electricity • Key Rivers: – The Nile River • Longest in world 4,160 Miles • Perfect for farmlands to support a large population (Ancient Egypt) • Now a source of power with the Aswan Dam (Mixed Blessing) – The Congo River • Empties into Atlantic from Central Africa • Used for hydroelectric power • Not useful fro transportation – Niger River • In West Africa • First flows north then south. • Used for irrigation, fishing and some travel – Zambezi River • In southern Africa • Rushes over Victoria Falls • Provides a border and power to Zimabwe and Zambia Natural Resources • • • River’s are a source of precious metals – Gold and diamonds • West Africa caught European interest for its gold Today African Nations sell many other valuable resources to the industrial world – D.R. of Congo and Zimbabwe- copper – South Africa, D.R. of Congo, Botswana- platinum and cobalt – Nigeria and Angola- offshore oil platforms – Libya, Algeria, Gabon and Sudan- Oil deposits Many resource profits flow out of Africa due to lack of money Resources in Africa are unevenly distributed • Some can farm like Uganda, but most is not fertile and rainfall is inconsistent •
