Did you know?

Did you know that when water changes from a liquid to a gas, it is called evaporation? This phase change is an important part of the water cycle, where water evaporates from bodies of water, plants release moisture through a process called transpiration, and even from the ground in the form of groundwater. Eventually, the water vapor in the atmosphere condenses to form clouds, and when these clouds become saturated, precipitation occurs in the form of rain, snow, or hail. Run-off refers to water flowing over the ground and into bodies of water, completing the water cycle. So next time you see rain or notice water disappearing from a puddle, you'll know that it's all part of the fascinating process of water changing from liquid to gas!
