The Atlantic Ocean occupies an elongated, S-shaped basin extending longitudinally between Europe and Africa to the east, and the Americas to the west.

The Atlas Mountains are a mountain range in the Maghreb in North Africa. They separate the Sahara from the Mediterranean Sea and the Atlantic Ocean; the mountain range stretches around 2,500 km (1,600 mi) through Morocco, Algeria and Tunisia. The range's highest peak is Toubkal, in central Morocco, with an elevation of 4,167 metres (13,671 ft). The Atlas Mountains are primarily inhabited by Berber populations.

The Kalahari Desert is a large semiarid sandy savanna in Southern Africa covering 900,000 km2 (350,000 sq mi), extending into Botswana, Namibia and South Africa. Unlike a true desert, much of the Kalahari supports grasses, thorny shrubs and scattered trees, and is home to substantial wildlife populations despite its low and unpredictable rainfall.

The Namib is a coastal desert in Southern Africa. According to the broadest definition, the Namib stretches for more than 2,000 kilometres (1,200 mi) along the Atlantic coasts of Angola, Namibia and northwest South Africa, extending up to 200 kilometres inland from the coast to the base of the Great Escarpment. Its name derives from a Nama word meaning "vast place," and it is considered the oldest desert in the world.

The Ethiopian Highlands, also known as the Abyssinian Highlands, is a rugged mass of mountains extending from Ethiopia to Eritrea in Northeast Africa. It forms the largest continuous area of its elevation on the continent, with little of its surface falling below 1,500 m (4,900 ft), while its summits reach heights of up to 4,550 m (14,930 ft). It is sometimes called the "Roof of Africa" due to its height and large area. This elevated surface is bisected diagonally by the Great East African Rift System, which extends from Syria to Mozambique across the East African Great Lakes.

The Danakil Depression is a large valley of approximately 200 by 50 km (124 by 31 mi), across the north of the Afar Region of Ethiopia and Eritrea.
