What is the water cycle and how does it help us?
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.
What is our role in the water cycle?
Bodies of water, clouds, evaporation and condensation all play vital roles in the water cycle, but so do living things. Close to 10 percent of all water enters the water cycle due to plant transpiration. Animals contribute to the water cycle via respiration, perspiration and urination.
What is the human impact on water?
