Discover the wonders of the water cycle with this engaging KS2 Science quiz! Learn about the cool processes like evaporation, condensation, precipitation, and surface runoff.
Did you know only 3% of Earth's water is fresh, and most is icy? Luckily, the small bit we drink and share with plants and animals is always recycled. Water turns into vapour from the sea (evaporation), forms clouds through condensation, and then falls as rain (precipitation). It travels downhill, joins rivers, and goes back to the sea, starting the cycle again!
What's another name for precipitation? Where does most water evaporation happen? Test your science skills with this Water Cycle quiz!

Fresh water can fall as rain, hail, sleet or snow
|
Groundwater is stored in soil and in underground layers of sand and permeable stone known as aquifers

Plants release water vapour through tiny pores (holes) in their leaves - these pores are called 'stomata'
|
Surface water evaporates and returns to the atmosphere as water vapour
|

You can see water condensation after you've had a shower - the water vapour in the air condenses as it cools down, leaving water droplets on the walls, windows and bathroom mirror
|
That's why some clouds bring rain - the water vapour condenses and then falls to earth

Water freezes and becomes a solid (ice) at 0o Celsius
|
Another name for water vapour is steam
|
||||||||||||||||||||||||
Steam is invisible water vapour (gas). When we see steam from a kettle or shower, the steam also contains tiny water droplets (liquid), making it visible
|
Precipitation follows condensation - and the whole water cycle begins again!
