World Rivers Knowledge Quiz – Rivers and Civilizations

The first civilizations grew along rivers. Egypt depended on the Nile, Mesopotamia on the Tigris and Euphrates, India's Harappan cities on the Indus and early China on the Yellow River. Floods brought fertile soil, and rivers provided water and transport.

Today, rivers still supply drinking water, farmland irrigation and hydroelectric power. Dams on rivers such as the Yangtze, Nile and Mekong produce huge amounts of electricity but also change fish migration and the flow of sediment to deltas.
