Read tha example below then talk about the questions with someone at home.
Where does rain come from?
Have you ever wondered where the rain comes from? It falls from clouds in the sky but how does it get there?
Water is never made. It exists in different states. That means it is a solid, liquid or gas. When water is frozen it is solid. When water is heated it turns to steam or water vapour which is a gas.
At the very tops of mountains the air is cold. Therefore water is frozen. It forms the ice and snow tops on mountains. If it is heated by the sun, then the ice begins to melt and turn to water. This water trickles into streams and the streams collect more water and make rivers. The rivers run down the sides of mountains and so fill up the seas and oceans.
Above the rivers, seas and oceans the sun causes water to heat up and turn to water vapour. It evaporates from the land and goes up to the sky. High in the sky, the temperature is lower and the air cools. Cool air cannot contain as much water vapour as hot air. The water vapour turns to tiny droplets. These droplets collect together and form clouds.
