Detailed explanation-1: -The water cycle is powered by heat energy from the Sun.
Detailed explanation-2: -Solar energy is created by nuclear fusion that takes place in the sun. Fusion occurs when protons of hydrogen atoms violently collide in the sun’s core and fuse to create a helium atom. This process, known as a PP (proton-proton) chain reaction, emits an enormous amount of energy.
Detailed explanation-3: -Heat from the Sun causes water to evaporate from oceans, lakes and streams. Evaporation occurs when liquid water on Earth’s surface turns into water vapor in our atmosphere. Water from plants and trees also enters the atmosphere. This is called transpiration.
Detailed explanation-4: -Like evaporation, condensation is also influenced by the sun. As water vapor cools, it reaches its saturation limit, or dew point. Air pressure is also an important influence on the dew point of an area. As is the case with evaporation and condensation, precipitation is a process.
