Angola is a country in south-central Africa. Angola is the world’s twenty-third largest country. The coast is for the most part flat, with occasional low cliffs and bluffs of red sandstone. The plateau has an altitude ranging from 4000 to 6000 ft (1,200 to 1,800 m). It consists of well-watered, wide, rolling plains, and low hills with scanty vegetation. In the east the tableland falls away to the basins of the Congo and Zambezi, to the south it merges into a barren sandy desert.
Malawi is a landlocked country in southeast Africa.

The Shire River flows from the south end of the lake and joins the Zambezi River 250 miles (400 km) farther south in Mozambique.
