Teaching English through Geography: Water Cycle
Water Cycle Step #1: Water evaporates from the Earth’s surface . If you spill a glass of water outside you will notice that a few hours later the water is gone! That is because water slowly turns from a liquid into a gas called water vapour. The process of water turning from a liquid into a gas is called evaporation. Evaporation happens faster on a hot day. That is because the evaporation of water outside takes energy from the sun! The hotter it is outside, the faster water will evaporate. Since water in its gas form has no colour, we cannot see it. It just goes into the air. Water Cycle Step #2: Water condenses to form clouds Water vapour rises up in the sky due to the sun’s heat. Once the water vapour rises high enough it condenses into water droplets. Condensation is the process of water turning from a gas into a liquid . You have probably experienced condensation if you have had a cold glass of water at a restaurant. As the cold glass sits on the table, water vapour from the...
