Science Quiz - The Water Cycle (Questions)

Water moves around Earth in a continuous cycle. In KS2 Science, pupils learn how evaporation, condensation, and precipitation keep water moving between land, sea, and sky.

Fascinating Fact:

The Amazon rainforest releases so much water vapour through transpiration that it makes its own weather.

In KS2 Science, the water cycle is taught to explain how water is reused on Earth. Evaporation, condensation, and precipitation work together to keep rivers, lakes, and plants supplied.

Key Terms

Evaporation: The process where liquid water changes into water vapour.
Condensation: When water vapour cools and turns back into tiny liquid droplets.
Precipitation: Water falling from the sky as rain, snow, hail, or sleet.

Frequently Asked Questions (Click to see answers)

What are the four stages of the water cycle?

The four main stages are evaporation, condensation, precipitation, and collection. Together they keep water moving around the Earth.

Why is the water cycle important for life?

The water cycle is important because it distributes fresh water to plants, animals, and people, helping to support all forms of life on Earth.

What is transpiration in the water cycle?

Transpiration is when plants release water vapour into the air through their leaves, adding to the moisture in the atmosphere.

Science Quiz - The Water Cycle (Answers)

1.

What do we call fresh water falling from the atmosphere to the Earth's surface?

[ ]	Condensation
[x]	Precipitation
[ ]	Evaporation
[ ]	Transpiration

Fresh water can fall as rain, hail, sleet or snow

2.

Some of the water from rain, hail, sleet or snow collects in streams, rivers, lakes and the sea. Where does most of the rest of the water go?

[ ]	Storage tanks
[ ]	Reservoirs
[x]	Into the ground
[ ]	In gutters

Groundwater is stored in soil and in underground layers of sand and permeable stone known as aquifers

3.

Plants draw water out of the ground and release water vapour into the atmosphere. What is this process known as?

[x]	Transpiration
[ ]	Evaporation
[ ]	Condensation
[ ]	Precipitation

Plants release water vapour through tiny pores (holes) in their leaves - these pores are called 'stomata'

4.

Water on the surface of roads and pavements disappears over time. What has happened to the water?

[ ]	It has precipitated
[ ]	It has condensed
[x]	It has evaporated
[ ]	It has stopped existing

Surface water evaporates and returns to the atmosphere as water vapour

5.

What happens to water vapour when it cools?

[ ]	It evaporates
[ ]	It precipitates
[ ]	It transpires
[x]	It condenses

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

6.

Which of these is condensation in the atmosphere?

[ ]	Tornadoes
[x]	Clouds
[ ]	Lightning
[ ]	Hurricanes

That's why some clouds bring rain - the water vapour condenses and then falls to earth

7.

What do we call water that is in a solid state?

[ ]	Liquid
[ ]	Water vapour
[x]	Ice
[ ]	None of the above

Water freezes and becomes a solid (ice) at 0^o Celsius

8.

What do we call water that is in the form of a gas?

[ ]	Liquid
[x]	Water vapour
[ ]	Ice
[ ]	None of the above

Another name for water vapour is steam

9.

When a kettle is boiling, it produces visible steam. What does this steam contain?

[x]	Gas and liquid water
[ ]	Water as a solid and a gas
[ ]	Water in its liquid and solid forms
[ ]	Water as gas, liquid and solid

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

10.

What stage of the water cycle directly follows water's condensation in the atmosphere?

[ ]	Evaporation
[ ]	Transpiration
[x]	Precipitation
[ ]	None of the above

Precipitation follows condensation - and the whole water cycle begins again!
