Which best explains how a watershed compares to a river basin?

• A watershed is a ridge of land separating bodies of water, and a river basin flows over the ground surface like runoff.

• A watershed is a river connecting to a larger river, and a river basin is a land area supplying water to the watershed.

• The total amount of water in the hydrosphere decreases over time due to the process of evaporation.

• The total amount of water in the hydrosphere increases over time due to the process of precipitation.

• The total amount of water in the hydrosphere remains the same over time, but changes form due to the water cycle.

• The total amount of water in the hydrosphere both decreases and increases over time due to competing processes such as evaporation and precipitation.
