Answer sheet

1. Water vapour cooling to form droplets — Condensation turns vapour into liquid droplets, forming clouds.
2. 97% — About 97% of Earth's water is in the oceans.
3. In ice caps and glaciers — Most fresh water is frozen in ice caps and glaciers.
4. Removes salt from seawater — Desalination removes salt to produce drinking water.
5. Rainfall is low in many areas and highly variable — Australia's rainfall is low and unreliable in many regions.
6. groundwater — Groundwater fills spaces in soil and rock.
7. precipitation — Precipitation is water falling from clouds.
8. catchment — Catchments collect and channel rainfall.
