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 do we call the entire land area that drains rainfall and snowmelt into a single river system: a watershed (drainage basin) or an atoll?

3. 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?

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

5. What do we call water that flows over the land surface into streams, rivers and the sea after rainfall: surface runoff or sublimation?

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

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

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

9. 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?

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

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

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