The water cycle & freshwater

1. Is water in an open shallow pan on a sunny, breezy afternoon likely to evaporate faster or slower than water in a narrow bottle in the shade?

2. Where is the largest reservoir of water on Earth (about 97% of all Earth’s water) stored: in the oceans and seas, or in rivers?

3. What stage of the water cycle occurs when rising water vapour cools high in the atmosphere and forms tiny cloud droplets: condensation or infiltration?

4. What forms when cold air cools water vapour below 0 °C high in clouds so ice crystals grow into six-sided flakes: snow or dew?

5. What do we call the upper level of underground rock or soil that is completely saturated with groundwater: the water table or the treeline?

6. What do we call the release of water vapour into the air from plant leaves through their stomata: transpiration or condensation?

7. What is the dry region on the leeward (downwind) side of a mountain range called: a rain shadow or a delta?

8. What happens to river discharge shortly after heavy rainfall in its drainage basin: river flow increases, or river flow stops?

9. Does the water cycle create brand-new water or continuously recycle the same water molecules through different states?

10. Where is most of Earth’s fresh water locked up: in glaciers and polar ice caps, or in clouds?

11. What do we call an underground layer of permeable rock, sand or gravel that holds groundwater: an aquifer or a canopy?

12. How does paving over grassy soil with impermeable concrete affect rainwater during a storm: it increases surface runoff, or it increases infiltration?
