Explanation:

[STC001617] The Congo is the only major river to cross the equator twice; it does so on both sides of the African continent. The Congo flows 2,920 miles from the Chambeshi River in Zambia, its water source, through the Congo rainforest, and into the Atlantic Ocean. The Congo is noteworthy for a variety of reasons as one of the continent’s essential water sources: It is the second longest river in Africa after the Nile, its drainage basin is the second largest in the world after the Amazon, and it is the world’s deepest river, reaching a maximum depth of 720 feet. Contrary to other rivers, the Congo River’s volume does not alter considerably due to the tropical environment it passes through because it is always rainy season on one side or the other.
