The African Landscape • Africa is the second-largest continent in the world. – triple the area of the United States. – extremes, from sandy deserts to lush tropical rain forests.

An Unusual Continent • Most of Africa is a large plateau. – A plateau is a highland area of fairly flat land.

An Unusual Continent • The rivers that flow across the plateau fall over waterfalls to a narrow strip of coastal plain. • Africa’s coastline is smooth and mostly unbroken by natural harbors.

A Vast Desert • The Sahara covers most of northern Africa – 3. 5 million square miles, the world’s largest desert. • Thousands of years ago, this region had rivers, trees, and grasslands.

The Sahel • The Sahel is a fertile region with limited and unpredictable rainfall along the southern edge of the Sahara. – The word sahel is Arabic for “shore, ” as if the Sahara were a great sea of sand. • Grasslands cover the Sahel. It also supports crops and herds of animals. – Droughts, or long dry spells, are a constant threat to the people who live in the Sahel.

Vegetation Zones • Each zone has its own climate and types of plants that fit its climate. • A savannah is a broad grassland with scattered trees. The African savannah has wet and dry seasons. • South of the savannah, along the Equator, lies the rain forest, a zone of towering trees, dense leaves, and climbing vines. – The rain forest is hot and wet year-round. Thousands of kinds of plants and animals live in this steamy jungle. – Some of the rain forest has been cut down due to modernization and farming

The Niger River • The main river of West Africa is the Niger River. It flows east into the Sahel from the rainy highlands of West Africa. Then it curves northeast through the desert. Finally, it flows southeast across the savannah to the Atlantic Ocean.
