Which of the following terms refers to the largest watersheds on the continent?

• A. Streams
• B. River basins
• C. Creeks
• D. Lakes

Answer: (B)

The term that refers to the largest watersheds on the continent is river basins. A river basin encompasses the land area that drains into a particular river and its tributaries, collecting all the precipitation that falls within its boundaries. This includes both surface water and groundwater, making river basins significant hydrological units. They can cover vast areas, often encompassing multiple smaller watersheds and contributing to larger bodies of water like oceans or seas. In contrast, streams and creeks are smaller bodies of flowing water within these larger systems and do not represent the overall drainage area associated with a major river. Lakes, while important aquatic ecosystems, are bodies of standing water rather than a system that drains land, which further differentiates them from the concept of a watershed. Thus, river basins are the correct terminology for describing the largest watersheds on the continent.
