Which choice best describes the parts of the water cycle? The sun's thermal energy causes water on the earth to evaporate. The w
Travka [436]

Answer:

The sun's thermal energy causes water on the earth to evaporate. The water vapor then condenses and forms precipitation. The precipitation then falls back to the surface of the earth.

Explanation:

<u>The water cycle is an illustration of how water continuously moves or circulates between the atmosphere and the various parts of the earth. </u>

<em>Evaporation of water from the surface of the earth by the thermal energy from the sun causes water to leave the surface of the earth into the atmosphere. When the atmospheric water vapor (humidity) at the upper strata of the atmosphere becomes high, the vapor condenses to form clouds which later forms precipitation that falls back to the surface of the earth.</em>

The ocean's tidal energy does not cause water to cycle on earth.
