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.

Which best describes how the total amount of water present in the hydrosphere varies over time?

• 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.

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

• They would decrease because CO2would be absorbed into the ocean from the atmosphere.

• They would increase because CO2 would be released from the ocean into the atmosphere.

• They would decrease because CO2 would be released from the ocean to the atmosphere.

• They would increase because CO2 would be absorbed into the ocean from the atmosphere.
