The main source of heat that makes water on the earth evaporate is the thermal energy from Sun.
The major source of water on Earth is the oceans, which hold about 97% of the planet's water. Other sources include rivers, lakes, glaciers, and groundwater.
The primary source of water on Earth is from precipitation, which includes rain, snow, sleet, and hail. This water falls from the atmosphere to the surface of the Earth, replenishing bodies of water like rivers, lakes, and oceans.
Sun is a source of energy.It powers earth's water cycle.
The main source of water in the water cycle is the Earth's oceans, which account for about 97% of the planet's water. This water evaporates due to heat from the sun, forming water vapor that rises into the atmosphere and eventually condenses into clouds to form precipitation.
The most likely source of the water which composes the Earth's oceans is comets, which impacted the Earth in its earlier history.
