I know the water cycle. I really do. But I still can’t quite understand how so much water gets up to the sky. Water is HEAVY. Cumulonimbus clouds have been said to “weigh” up to one million tonnes. And you see the result when it rains. LOTS of water falls from the sky. LOTS. And it has to get up there somehow. And I know that it evaporates from the oceans and lakes but…that’s a LOT of energy. Clouds. Amazing.
