GEOLOGY

Detailed explanation-1: -When rain falls, much of the water runs across the surface of the land toward a stream, river, pond, or lake as surface runoff. The land area that drains runoff to the stream, or other surface water body, is called a watershed, or drainage basin.

Detailed explanation-2: -A WATERSHED is any area of land that water flows across or through.

Detailed explanation-3: -It’s a land area that channels rainfall and snowmelt to creeks, streams, and rivers, and eventually to outflow points such as reservoirs, bays, and the ocean.

Detailed explanation-4: -A watershed is an area of land that drains or “sheds” water into a specific waterbody. Every body of water has a watershed. Watersheds drain rainfall and snowmelt into streams and rivers. These smaller bodies of water flow into larger ones, including lakes, bays, and oceans.

Detailed explanation-5: -For example, the watershed of a lake would include not only the streams entering that lake but also the land area that drains into those streams and eventually the lake. Drainage basins generally refer to large watersheds that encompass the watersheds of many smaller rivers and streams.
