On an island near the equator, the sun's energy causes ocean water to evaporate during the day. In the afternoon, heavy rains fall. This process is repeated during the summer months. What does this example best show?

How most water on Earth is in the form of water vapor

How land is the main source of water during the water cycle

How the sun is the main source of energy for the water cycle

How the ocean is large enough that it never runs out of water
