Physical Geography • The Big Idea • West Africa, which is mostly a region of plains, has climates ranging from arid to tropical and has important resources. • Main Ideas • West Africa’s key physical features include plains and the Niger River. • West Africa has distinct climate and vegetation zones that go from arid in the north to tropical in the south. • West Africa has good agricultural and mineral resources that may one day help the economies in the region.
Main Idea 1:West Africa’s key physical features include plains and the Niger River. Plains and Highlands • Plains cover most of the region. • Most cities are on coastal plains. • A few areas of highlands are scattered around the region. The only high mountains are the Tibesti Mountains.

Sahara West Africa’s climates are zonal, or organized by zone. The northern part of the region lies in the Sahara, the world’s largest desert. Almost no vegetation grows there. Dry, so few people live in many areas Sahel The semiarid Sahel is south of the Sahara. The area has a steppe climate, and rainfall varies from year to year. It has enough vegetation to support livestock. Desertification, the spread of desertlike conditions, is making the Sahel more like the Sahara every year. Main Idea 2:West Africa has distinct climate and vegetation zones that go from arid in the north to tropical in the south.
Savanna Lies south of the Sahel The savanna is an area of tall grasses and scattered trees and shrubs. When rain falls regularly, farmers can grow many crops. Humid Tropical Lies along the coasts of the Atlantic and the Gulf of Guinea Plentiful rain supports tropical forests. Many trees have been cut down to make room for people.

The climate in part of the region is good for agriculture. Ghana is the world’s largest producer of cacao, which is used to make chocolate. Coffee, coconuts, and peanuts are also grown in the region. Oil is the most valuable resource in the region. Found off the coast of Nigeria Other mineral resources include diamonds, gold, iron ore, and bauxite, the main source of aluminum.
