Water and carbon cycles

Junior High 6 questions

What water and carbon cycles means

You learn how water and carbon move through plants, air, soil and living things. This helps you understand rainfall, plant life, climate and how nature keeps materials moving in cycles.

What you will practise

Identify changes in the water cycle, such as evaporation and condensation.
Link rain, snow and hail to precipitation.
Recognise how plants release water vapour through leaves.
Follow carbon as it moves through plants, animals and the air.

Before you start

You should already know basic states of matter, especially liquid, gas and solid. It also helps if you can name common plant parts and simple weather terms.

Worked example

One question from this skill's own question bank, shown with its full working.

Question

In the water cycle, water vapour turning into liquid droplets is called…

evaporation
condensation
precipitation
transpiration

Answer: condensation

Working: Condensation is the change from gas (vapour) to liquid, forming clouds.

Common mistakes to avoid

Mixing up evaporation and condensation; remember vapour becomes liquid during condensation.
Calling every kind of rain water vapour; precipitation is water falling from clouds.
Forgetting that transpiration comes from plant leaves, not from the whole plant.
Thinking cycles stop at one step; trace the full path through nature.
