The most dominant geographical feature in Africa is the Sahara Desert. Stretching across much of North Africa, the Sahara is the largest hot desert in the world and significantly influences the continent's climate and ecosystems. It covers over 9 million square kilometers and features diverse landscapes, including sand dunes, mountains, and rocky plateaus. In addition to its harsh conditions, the Sahara is rich in cultural history and home to various nomadic tribes and ancient trade routes. Its prominence in geography and culture shapes the identity of the region.
