The average annual temperature in Soyo, for example, at the mouth of the Congo, is 79 °F (26 °C), whereas in Huambo, on the Bié Plateau, it is 67 °F (19 °C).Until the late 19th century, parts of Angola were covered with dense rainforest, mainly in the northern part of the Cabinda exclave, the western edge of the Malanje highlands, the northwestern corner of the Bié Plateau, and along some rivers in the northeast.Much of this forest has been greatly diminished by agriculture and logging, and now most of Angola’s surface is covered with different kinds of savanna (grasslands with scattered trees), ranging from savanna-forest mosaic in the north to thorn scrub in parts of the south.Natural or man-made fires occur frequently in savanna vegetation, and tree species are thus usually resistant to fire.From a narrow coastal plain, the land rises abruptly to the east in a series of escarpments to rugged highlands, which then slope down toward the centre of the continent.The coastal plain varies in width from about 125 miles (200 km) in the area south of Luanda to about 15 miles (25 km) near Benguela.Crystalline bedrock of Precambrian age (between about 540 million and 4 billion years old) emerges along the escarpment, and mineral deposits sometimes lie close to the surface.Considerable erosion has occurred in this area, and laterite formations are common.
The Maiombe forest in the northern part of the Cabinda exclave receives the greatest amount of rainfall, about 70 inches (1,800 mm) per year, and Huambo, on the Bié Plateau, receives 57 inches (1,450 mm).
Some rivers in the southeast of the plateau flow into the Zambezi River, which itself crosses the Cazombo region in the far eastern extension of the country.
Other rivers in this area feed the Okavango Swamps of northwestern Botswana.
Most of the plateau in the eastern two-thirds of the country lies buried under deep deposits of infertile windblown Kalahari sands.
The river gravels of the northeast contain diamonds, and rare kimberlite pipes occur in this area.intertropical convergence zone, the northward flow of the cold Benguela Current off the coast, and elevation.
