This mountain system runs from southwestern Morocco along the Mediterranean coastline to the eastern edge of Tunisia. Several smaller ranges are included, namely the High Atlas, Middle Atlas and Maritime Atlas. The highest peak is Mt. Toubkal in western Morocco at 13,671 ft. (4,167 m).
Congo River Basin:
The Congo River Basin of central Africa dominates the landscape of the Democratic Republic of the Congo and much of neighboring Congo. In addition, it stretches into Angola, Cameroon, the Central African Republic and Zambia. The fertile basin is about 1,400,000 sq. miles (3,600,000 sq. km) in size and contains almost 20% of the world's rain forest. The Congo River is the second longest river in Africa, and it's network of rivers, tributaries and streams help link the people and cities of the interior.
The Ethiopian Highlands are a rugged mass of mountains in Ethiopia, Eritrea (which is sometimes referred to as the Eritrean Highlands), and northern Somalia in the Horn of Africa. The Ethiopian Highlands form the largest continuous area of its altitude in the whole continent, with little of its surface falling below 1500 m (4,921 ft), while the summits reach heights of up to 4550 m (14,928 ft). It is sometimes called the Roof of Africa for its height and large area.
Great Rift Valley:
A dramatic depression on the earth's surface, approximately 4,000 miles (6,400 km) in length, extends from the Red Sea area near Jordan in the Middle East, south to the African country of Mozambique. In essence, it's a series of geological faults caused by huge volcanic eruptions centuries back, that subsequently created what we now call the Ethiopian Highlands, and a series of perpendicular cliffs, mountain ridges, rugged valleys and very deep lakes along it's entire length. Many of Africa's highest mountains front the Rift Valley, including Mount Kilimanjaro, Mount Kenya and Mount Margherita.
