Did you know?

Did you know that when water changes from a gas to a liquid, it is called condensation? This phase change occurs during the water cycle, which is the continuous movement of water on Earth. Condensation occurs when water vapor cools down and turns into liquid droplets, forming clouds. These clouds then release moisture in the form of precipitation, such as rain, snow, sleet, or hail. Precipitation plays a crucial role in providing water for various ecosystems and human activities. Additionally, when water falls to the ground, it can either become surface run-off, flowing into rivers, lakes, and oceans, or seep into the ground as ground water. Evaporation, on the other hand, is the process where liquid water converts into water vapor, completing the water cycle.
