Question

What does radiation have to do with the water cycle?

Answer 1

It evaporates water and forms and moves clouds

Explanation:

Solar power is the main source of energy that drives the water cycle. Without it, you cannot mention any hydrologic cycle. First, it evaporates water from water surfaces (lakes, seas, oceans, rivers, swamps). This water converts into gas and builds clouds. Wind (it also depends on the sun) helps these clouds to be agglomerated, moved away, etc.

If the precipitation is in snow form, solar energy melts down snow and cause runoff.
