The processes that show how water moves through Earth's systems using energy from the sun and gravity are:
- Evaporation of water from oceans, lakes, and rivers due to solar heating.
- Condensation of water vapor into clouds due to cooling in the upper atmosphere.
- Precipitation of water in the form of rain, snow, or sleet back to the Earth's surface.
These three processes are part of the water cycle, which is driven by solar energy and involves gravity. The option regarding desalination using natural geothermal energy does not fit within the typical water cycle processes.
