Water Cycle

Water turns from a liquid to a gas when it evaporates. Energy from the Sun can evaporate water from all places on the Earth’s surface such as puddles, ponds, lakes and oceans.

After evaporation water can cool and convert from gas to liquid, often forming clouds.

Precipitation occurs when rain, snow, hail and sleet fall from the sky.

Much water will be absorbed into the ground after precipitation but if a large volume falls or the ground is already wet some water can run along the surface of the ground.

This occurs when water that has fallen as precipitation is absorbed into the ground.

Plants need to maintain a constant steam of water to their leaves for transport and support. So they allow some water to evaporate as water vapour from their leaves.
