Answer:
Rivers are the backbone of human civilizations which provide freshwater that is the basic necessity for human life. We cannot live without water and rivers are the largest water bodies for freshwater. In fact, all civilizations in the past and present were born near river banks
A river is a ribbon-like body of water that flows downhill from the force of gravity. A river can be wide and deep, or shallow enough for a person to wade across. A flowing body of water that is smaller than a river is called a stream, creek, or brook.
