the average annual precipitation over Earth equals the amount of water that evaporates
No, the total amount of water on Earth remains relatively constant due to the water cycle. Water evaporates from bodies of water, condenses into clouds, and falls back to Earth as precipitation. This cycle ensures that the overall amount of water on Earth remains constant.
That's what we humans call the "Water Cycle"
80 percent evaporates from the ocean. Incorrect !!! All water in the water cycle of Earth evaporates from oceans and works its way back to the ocean. Evaporation from rivers, lakes, ponds etc. is a temporary stage of the overall trip back to its origin in the oceans.
Water evaporates mostly from water bodies.
This evaporated water is from bodies of water.
This water form clouds.
The amount of water in the ocean temporary decrease.
This source is water from oceans.
Clouds form in the upper troposphere. They form like this: Water on Earth's surface evaporates (turns into water vapor), and rises. When it gets to the upper troposphere, the water vapor starts turning back into water, staying as mist mostly, and mixes with dust. When the amount of water is to heavy, it starts to precipitate. Then, the precipitation evaporates on Earth's surface and the cycle begins again.
water evaporates from the earth and condenses in the sky
This is the troposphere.
