Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
As time goes by, and water goes through the water cycle again and again, the amount of water on Earth ____
A
Increases
B
Decreases
C
Stays the same
D
Goes up and down
Explanation: 

Detailed explanation-1: -When the temperature and saturation is correct, the water precipitates as rain back to the earth. This is the water cycle. During this whole process, the overall amount of water remains the same. This has been the case since the last two billion years.

Detailed explanation-2: -Water continually evaporates, condenses, and precipitates, and on a global basis, evaporation approximately equals precipitation. Because of this equality, the total amount of water vapor in the atmosphere remains approximately the same over time.

Detailed explanation-3: -The water cycle shows the continuous movement of water within the Earth and atmosphere. It is a complex system that includes many different processes. Liquid water evaporates into water vapor, condenses to form clouds, and precipitates back to earth in the form of rain and snow.
