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.
