What energy keeps the water cycle going? Evaporation powers the water cycle because the vapor rises up to the clouds and condenses.
The wind's energy blows the clouds around the earth's atmosphere and causes the water cycle.
The air's energy cools water vapor, condensation occurs, and precipitation falls.
The sun's energy heats the earth's surface causing water to heat and evaporate.
