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.

• A watershed is a land area supplying water to small rivers, and a river basin is comprised of many interconnected watersheds and their tributaries.

• A watershed flows over the ground surface as runoff, and a river basin is a layer of permeable rock and soil in which water fills the cracks and pores.

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.

How is the surface of ocean water changed when water evaporates?

• Salinity increases because salt enters the ocean as water vapor in the air cools.

• Salinity decreases because the salt enters the atmosphere with the water vapor.

• Salinity decreases because the salt enters the atmosphere leaving pure water behind.

• Salinity increases because salt is left behind when the water vapor enters the atmosphere.
