Where is the world’s longest river located?

The world’s longest river is the Nile River, which runs for about 6,650 kilometers (4,130 miles) through northeastern Africa. It flows through eleven countries, including Uganda, Sudan, and Egypt, before emptying into the Mediterranean Sea. The Nile has been a vital source of water, agriculture, and transportation for the civilizations along its banks for thousands of years. The river is formed by the confluence of two major tributaries: the White Nile and the Blue Nile.
