Descripción
The water cycle describes the flow of water on Earth. The biggest stock of water on Earth is in the oceans. While there are many small processes in the water cycle that help water get from one place to another, there are a few main processes that facilitate the others.Evaporation is when liquid water molecules gain enough energy to vaporize, or turn into a gas. When water vapor is cooled it condenses, or turns back into a liquid. We can see condensed water from setting a glass of cold water on the table or in the sky as clouds. Precipitation is when condensed water in the air (which forms clouds) falls to the earth, like rain. Transpiration is the process of water vapor releasing from plants and soil. This step is difficult to observe, but is a very important part of the water cycle.Observe evaporation and condensation in different environments.
