why energy from the sun is important to the water cycle?
Dear Juan, energy from the sun is important because it heats the water molecules which causes them to evaporate. Evaporation is when the water turns into a gas which is a part of the water cycle. After the gas cools it turns into condensation, or liquid water again.
The sun's energy provides the heat needed for the water to evaporate.
