AFRICA
Africa is the second largest continent in area and in population, covering about a fifth of the world's land area and has about one-seventh of its people.
The African continent is an immense plateau, broken by a few mountain ranges and bordered in some areas by a narrow coastal plain. It is a land of striking contrasts and great natural wonders. In the tropical rain forests of western and central Africa, the towering treetops form a thick green canopy. The world's largest desert, the Sahara, stretches across northern Africa. ve led to civil wars in several African countries.
It covers an area almost as large as the entire United States. Africa also has the world's longest river-the Nile. It flows more than 4,000 miles (6,400 kilometers) through northeastern Africa. Much of the continent is grassland. Elephants, giraffes, lions, zebras, and many other animals live in the grasslands located in eastern and southern Africa.
