Evaporation

Heat turns water into invisible vapour

Evaporation happens when the sun heats water in oceans, rivers and lakes. The water turns into water vapour — an invisible gas — and rises up into the air. This is how water moves from the earth's surface up into the atmosphere.

⚡ Fun Fact

The sun evaporates about 1 million tonnes of water from Earth's oceans every single second!

Key Points

Heat from the sun causes evaporation
Liquid water becomes water vapour
