Water can be a liquid, a solid or a gas. When it is a solid, it can be as hard as stone. When it is a liquid, it can run through your fingers. When it is a gas, you may not see or feel it.
Water can change from a solid to a liquid or to a gas easily. This is why we always have fresh water. Now let us find out how it does. The heat of the sun turns liquid water into gas from the oceans, seas, rivers and lakes. The heat also turns liquid water into gas from the ground, the plants and the animals. Water in the gas rises and turns into clouds in the air.
When the clouds come near a mountain, they rise high. As the clouds rise, they get cooler. The higher they rise, the cooler they become. Then more and more water gas turn into water drops. In this way, the drops of water in the clouds get bigger and bigger. Then they fall to the earth as rain.
