Democratic Republic of The Congo - Geography

Geography

The Congo is situated at the heart of sub-Saharan Africa and is bounded by (clockwise from the southwest) Angola, the South Atlantic Ocean, the Republic of Congo, the Central African Republic, South Sudan, Uganda, Rwanda, Burundi, Tanzania across Lake Tanganyika, and Zambia. The country lies between latitudes 6°N and 14°S, and longitudes 12° and 32°E. It straddles the Equator, with one-third to the North and two-thirds to the South. The size of Congo, 2,345,408 square kilometres (905,567 sq mi), is slightly greater than the combined areas of Spain, France, Germany, Sweden, and Norway.

As a result of its equatorial location, the Congo experiences high precipitation and has the highest frequency of thunderstorms in the world. The annual rainfall can total upwards of 80 inches (2,000 mm) in some places, and the area sustains the Congo Rainforest, the second largest rain forest in the world (after that of the Amazon). This massive expanse of lush jungle covers most of the vast, low-lying central basin of the river, which slopes toward the Atlantic Ocean in the west. This area is surrounded by plateaus merging into savannas in the south and southwest, by mountainous terraces in the west, and dense grasslands extending beyond the Congo River in the north. High, glaciated mountains are found in the extreme eastern region (Rwenzori Mountains).

The tropical climate has also produced the Congo River system which dominates the region topographically along with the rainforest it flows through, though they are not mutually exclusive. The name for the Congo state is derived in part from the river. The river basin (meaning the Congo River and all of its myriad tributaries) occupies nearly the entire country and an area of nearly 1,000,000 km2 (390,000 sq mi). The river and its tributaries (major offshoots include the Kasai, Sangha, Ubangi, Aruwimi, and Lulonga) form the backbone of Congolese economics and transportation. They have a dramatic impact on the daily lives of the people.

The sources of the Congo are in the Albertine Rift Mountains that flank the western branch of the East African Rift, as well as Lake Tanganyika and Lake Mweru. The river flows generally west from Kisangani just below Boyoma Falls, then gradually bends southwest, passing by Mbandaka, joining with the Ubangi River, and running into the Pool Malebo (Stanley Pool). Kinshasa and Brazzaville are on opposite sides of the river at the Pool (see NASA image).

Then the river narrows and falls through a number of cataracts in deep canyons (collectively known as the Livingstone Falls), and then running past Boma into the Atlantic Ocean. The river also has the second-largest flow and the second-largest watershed of any river in the world (trailing the Amazon in both respects). The river and a 45 km wide strip of land on its north bank provide the country's only outlet to the Atlantic.

The previously mentioned Albertine Rift plays a key role in shaping the Congo's geography. Not only is the northeastern section of the country much more mountainous, but due to the rift's tectonic activities, this area also experiences volcanic activity, occasionally with loss of life. The geologic activity in this area also created the famous African Great Lakes, three of which lie on the Congo's eastern frontier: Lake Albert (known previously as Lake Mobutu), Lake Edward, and Lake Tanganyika.

The Rift Valley has exposed an enormous amount of mineral wealth throughout the south and east of the Congo, making it accessible to mining. Cobalt, copper, cadmium, industrial and gem-quality diamonds, gold, silver, zinc, manganese, tin, germanium, uranium, radium, bauxite, iron ore, and coal are all found in plentiful supply, especially in the Congo's southeastern Katanga region.

On 17 January 2002 Mount Nyiragongo erupted in Congo, with the lava running out at 40 mph (64 km/h) and 50 yards (46 m) wide. One of the three streams of extremely fluid lava flowed through the nearby city of Goma, killing 45 and leaving 120,000 homeless. Four hundred thousand people were evacuated from the city during the eruption. The lava poisoned the water of Lake Kivu, killing fish. Only two planes left the local airport because of the possibility of the explosion of stored petrol. The lava passed the airport but ruined the runway, entrapping several airplanes. Six months after the 2002 eruption, nearby Mount Nyamulagira also erupted. Mount Nyamulagira also erupted in 2006 and again in January 2010.

World Wide Fund for Nature ecoregions located in the Congo include:

• Central Congolian lowland forests – home to the rare bonobo primate
• The Eastern Congolian swamp forests along the Congo River
• The Northeastern Congolian lowland forests, with one of the richest concentrations of primates in the world
• Southern Congolian forest-savanna mosaic
• A large section of the Central Zambezian Miombo woodlands
• The Albertine Rift montane forests region of high forest runs along the eastern borders of the country.

World Heritage Sites located in Democratic Republic of Congo are: Virunga National Park (1979), Garamba National Park (1980), Kahuzi-Biega National Park (1980), Salonga National Park (1984) and Okapi Wildlife Reserve (1996).
