GEOGRAPHY
Africa

To the north lies Sahara, the largest desert in the world. Equatorial area is covered by tropical rain forests.

Farther south there are areas of grassy flat highlands giving way to coastal plains. Major mountain ranges include Atlas in the north and Ruwenzri on the Uganda-Zaire border.

Kilimanjaro, Africas highest mountain, is a dormant volcano in Tanzania. To the east is the Great Rift Valley containing several huge lakes.

Some of the worlds longest rivers drain the continent, including the Nile, Niger, Zaire, and Zambezi.
