What is the largest physical feature in Africa?

The largest physical feature in Africa is the Sahara Desert, which spans approximately 9.2 million square kilometers (3.6 million square miles). This vast desert stretches across several countries in North Africa, including Algeria, Libya, and Egypt, and is characterized by its arid climate, sand dunes, and rocky plateaus. The Sahara is not only the largest hot desert in the world but also plays a significant role in the continent's ecology and climate.
