The Magic of the Water Cycle
The marvelous journey of water on Earth is called the water cycle. This cycle allows Earth to have a continuous supply of fresh water, which is crucial for all forms of life. It begins with the sun s heat causing water to evaporate from oceans, lakes, and even puddles on the street. This invisible water vapor rises into the sky and cools down to form clouds, a process known as condensation. When the clouds get heavy, the water falls back to the ground as rain, snow, or sleet - this is called precipitation. The water then collects in bodies of water like rivers and lakes, and the cycle begins again. Did you know the water you drink today could have been part of a cloud a week ago? That s the magic of the water cycle!
