Have you ever left a glass of water out for a long time? Did you notice that the water disappears after a few days? That's because it evaporated!
Evaporation is when water passes from a liquid to a gas.
Water that is held in lakes and rivers evaporates into the atmosphere. Since the ocean is so big, it is the biggest source for water evaporated into the atmosphere. Evaporation helps keep the water cycle going!
