Are clouds water vapor? If they are, why can we see them? If not, what are they then?
Clouds are not water vapor. They are water droplets or ice crystals

What supplies the power for the water cycle?
The sun and gravity

Does water or land cool slower? Does water or land heats up slower?
Water cools slower. Water heats up slower

What causes sea breezes?
A sea breeze is caused when the land is warmer than the sea. Warm air rises, so the sea breeze comes in and fill in the space.

How does the sun supply the energy in a hydroelectric plant?
The sun evaporates and precipitates the water onto the mountains, where it flows down into a lake, which powers the hydroelectric plant.

What causes a land breeze?
A land breeze occurs when the water is warmer than the land. Warm air rises, so the land breeze comes and fill in the space.
