This term, in science, we have been learning about the water cycle. We were surprised to learn that the water we drink has been around for millions of years!
This is all because water is a closed cycle. It never stops! Water in rivers, pods, lakes, streams and even puddles is heated up by the sum. As it heats up, it becomes water vapour, which rises into the atmosphere. This is called evaporation.
In the air, the water vapour cools down, turns back into water and begins to form clouds. This is called condensation.
When the clouds become too dense, the water then falls back to Earth as rain, hail or snow. This is called precipitation.
When it lands on Earth, it can land in streams, ponds, lakes, puddles and the ground. From there it runs back to the seas. This is called collection.
The cycle is continuous: it never stops.
Hannah, Thomas L, Kristie, Ben M, Ryan J and Grace have drawn annotated diagrams to explain the water cycle and show their understanding.
