Watersheds are defined as what?

• A. A region of ocean with high salinity
• B. A body of groundwater
• C. An area of land that separates waters flowing to different rivers, basins, or seas.
• D. An area where water evaporates

Answer: (C)

Watersheds are about how water moves across the land and into a common outlet. The key idea is that rainfall in a defined land area drains into a specific river, lake, or sea, and the boundary of that area is set by the high points or ridges that separate where water flows toward different outlets. So a watershed is the land area that collects precipitation and drains to one particular outlet. This isn’t about a region of the ocean, a groundwater body, or an area where water evaporates. Those describe different parts of the water cycle or storage, not the land area that channels surface water toward a single river or basin. An everyday way to picture it is to imagine a mountain ridge as a divider: rain on one side ends up in one river system, while rain on the other side ends up in a different system.
