A river is a natural flowing body of water that moves across the land, usually toward an ocean, sea, lake, or another river.

They vary in size from small streams to large, powerful waterways and often serve as vital resources for human communities.
History
↓↓
Rivers have existed since the formation of Earth’s surface and have been vital for human civilization. Ancient societies, such as those along the Nile, Tigris-Euphrates, Indus, and Yellow River, developed around rivers because they provided water, fertile soil, and transportation routes. Throughout history, rivers have shaped trade, culture, and settlement, and today they remain essential for ecosystems and human life.
