Did you know that the water you drink today could be the same water that dinosaurs drank millions of years ago? That s because of the water cycle! Imagine you re a water drop and let s go on a journey to see how this works. First, you start from a lake or river and rise up into the sky. This is called evaporation. It happens when the sun s heat turns you from liquid into gas. Then, you join other water vapor in the sky and turn back into liquid. This process is called condensation. It s like when you see drops forming on the outside of a cold drink on a hot day. Next, you fall back to the ground as rain or snow. This is called precipitation. You may land in a body of water, or you might land on a plant. Sometimes, if you land on a plant, you travel through it and evaporate from its leaves in a process called transpiration. Then, your journey starts all over again! So, the next time you drink a glass of water, remember: you re taking part in the water cycle that s been going on for millions of years!
