Answer:
The sun
Explanation:
The sun drives the water cycle. The sun evaporates water from the oceans, seas, lakes and other bodies of water and also from plants through the process of transpiration. The evaporated water then forms into clouds and when it gains enough mass it falls back to Earth. This is a closed system so that means that this is the same amount of water that has always been present on Earth.
They show that there was an ocean over the plains long ago, and fossils are always used to elaborate on the history of life/how it developed.
