The water cycle & freshwater

1. What energy source drives the global water cycle by warming ocean and land surfaces: the Sun or the Moon?

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

3. When ocean water evaporates into the air, does the dissolved salt evaporate with the water vapour or stay behind in the sea?

4. What happens when moist air is forced to rise over a mountain range: it cools, condenses and drops rain on the windward side, or it warms and dries?

5. What role do trees play in a watershed during heavy rain: their canopy intercepts rain and roots help water infiltrate soil, or they block all evaporation?

6. What stage of the water cycle occurs when liquid water at the ocean surface warms and turns into water vapour: evaporation or precipitation?

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

8. 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?

9. What combined term describes the total water vapour transferred to the atmosphere from both soil evaporation and plant transpiration: evapotranspiration or precipitation?

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

11. What stage of the water cycle occurs when cloud droplets grow heavy enough to fall as rain, snow, sleet or hail: precipitation or evaporation?

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