The source of the congo river system is
a. a short distance from the ocean
b. deep within the rain forest
c. near the niger river
d. about 9,000 miles from the ocean

The correct answer is letter B. The source of the Congo River system is found deep within the rain forest, particularly in the highlands and mountains of the East African Rift. Lake Tanganyika and Lake Mweru are also sources of the Congo River System. The lake feeds the Lualaba River which eventually follows and becomes a part of the Congo.
