99.9% of Earth's energy comes from the Sun. It is usual, especially in the natural water cycle for the energy to evaporate water to come from the Sun. Of course you could also use the heat from a nuclear reactor.

Where does the energy from running water in streams come from?

The sun. Evaporation leads to rain in the mountains & gravity does the job from there.


Is it true or false that the energy for evaporation comes from the sun?

It is true. The sun's energy drives all parts of the water cycle, including evaporation.


Does the energy from evaporation come from the sun?

Yes, it does because the suns rays heat the the water so that is can evaporate


What energy source causes evaporation?

Solar energy is the main energy source that causes evaporation. The heat from the sun provides the energy needed to convert water from liquid to gas, leading to evaporation.


How does the sun drive the water cucle?

Sun is a source of energy. It helps in evaporation.


What step of the water cycle requires energy?

evaporation requires energy from the sun


Why can water evaporation not occur with out the sun's energy?

Because the suns heat is what causes natural evaporation.


Is weather energy?

No, not in itself. Weather is the result of energy. The energy involved comes from the sun. As there are temperature differences, there are differences in pressure, and wind is produced. Heat and wind are energy, and both come from the energy of the sun and the rotation of the earth. Cold is the absence of sun, wind indirectly comes from the sun, and rain is the result of evaporation and condensation which also involve the sun.


Where does the energy needed for evaporation come from in nature?

The energy needed for evaporation in nature primarily comes from solar radiation. The sun's energy causes water molecules to gain enough kinetic energy to break free from the liquid phase and enter the gaseous phase. This process is crucial for the water cycle and plays a significant role in various environmental processes.


What role does the sun play in the evaporation process?

The sun provides the heat energy needed for evaporation to occur. When the sun's energy reaches the Earth's surface, it causes water molecules to gain enough energy to break free from the liquid and turn into vapor. This vapor then rises into the atmosphere, leading to the evaporation process.


Why is the sun significant in the water cycle?

Sun helps in evaporation. it provides thermal energy.


How does the energy from the sun affect earth's water cycle?

Energy from sun supports evaporation. It is 1st step of water cycle.
