Question

what is the energy source of the water cycle?
a evaporation
b sun
c precipitation
d clouds

Explanation:

The water cycle involves processes like evaporation. The sun's energy heats water on Earth's surface (oceans, lakes, etc.), causing evaporation. Evaporation is a process, not an energy source. Precipitation (rain, snow) is a result of the water cycle. Clouds are formed from water vapor. The sun provides the energy that drives the entire water cycle.

Answer:

B. Sun
