during the water cycle, water evaporates, rises into the atmosphere, and eventually falls back to earth's surface as precipitation. what is the original source of energy that produces these changes

Answers

When warmed by the sun, water on the surface of oceans and freshwater bodies evaporates, forming a vapor. Water vapor rises into the atmosphere, where it condenses, forming clouds. It then falls back to the ground as precipitation. Moisture can also enter the atmosphere directly from ice or snow.

The original source of energy for the water cycle is sunlight. It falls on the earth's surface and causes the water to evaporate.

As the sunlight falls on the surface of the earth's surface, the water in the oceans or water bodies evaporates and the glaciers sublimes which converts directly from solid to gas or vapor form.

The vapor rises up in the atmosphere and forms the clouds this process is known as condensation. These water vapors falls back to earth's surface by the process of precipitation or raining.

This is known as water cycle. Therefore, the answer for the given question is sun energy or sunlight.
