forests, vast grasslands, and the world’s largest desert.
After Pangaea, the supercontinent, broke up 200 million years agoAfrica moved very
little, unlike Americas, Antarctica, Australia, India
Africa is second largest continent
A huge plateau covers most of Africa, rising inland from coastsmost of Africa is
at least 1,000 feet above sea level
known as the “plateau continent”

The Congo River is the 9th longest river in the world and flows over 2,900 miles.
The Congo and its tributaries make it one of the largest river networks in the world!
Surrounding the Congo River, is the Congo River Basin, which is some of the most fertile land in the world.

During the wet season, the flow of water makes it the largest waterfall in the world! (In terms of volume).
The natives call it Mosi-o-Tunya, which means, the “Smoke that thunders.”

The Sahara is largest desert in world; name means “desert” in Arabic
It stretches 3,000 miles from the Atlantic to the Red Sea; 1,200 miles north to south temperatures as high as
136 degrees in summer, freezing at night
fewer than 2 million of Africa’s 800 million people live in Sahara
6,000 feet under the Sahara are aquifers — stores of underground water
When this water comes to the surface it creates an oasis
Sahara and other deserts may go years without rain
Tropical grassland covers most of Africa
Serengeti Plain — northern Tanzania grasslanddry climate, hard
soil prevent growth of trees, crops
Serengeti National Park has best grasslands in the worldsome grasses grow
taller than a person ideal for grazing animals
like wildebeests, gazelles, zebras
