Africa is home to diverse landforms, including vast plateaus, mountain ranges, and deserts. The Great Rift Valley is a significant geological feature that stretches from Ethiopia to Mozambique, creating deep valleys and highlands. The Atlas Mountains in North Africa and the Drakensberg in South Africa are notable mountain ranges that contribute to the continent's varied topography. The Sahara Desert, the largest hot desert in the world, covers much of North Africa and features sand dunes, rocky plateaus, and salt flats. Additionally, the Nile River, the longest river in the world, flows through northeastern Africa, providing vital water resources to the surrounding regions.
