The amount of water that evaporates from earth is roughly equal to the amount that falls as precipitation.

Explanation:

In the hydrological cycle, evaporation consists of the conversion of liquid water into water vapor, which reaches the atmosphere. Once the water vapor condenses produces precipitation in the form of rain, snow or hail.

On the earth the amount of water that evaporates is proportional to the water that falls as precipitation. The mass of ocean water is substantially greater than the amount of land, so variations in the proportion of evaporated water and precipitation occur in the hydrological cycle:

This produces a certain grade of compensation in which, globally, the amount of water that evaporates from the earth is roughly equal to the amount that falls as precipitation.
