The water cycle & freshwater

Answers and reasoning. Review before teaching.

1. What do we call water that flows over the land surface into streams, rivers and the sea after rainfall: surface runoff or sublimation?
Surface runoff
Water that does not soak into the soil flows downhill as surface runoff.
2. What is the dry region on the leeward (downwind) side of a mountain range called: a rain shadow or a delta?
Rain shadow
Air descending the leeward slope warms and dries, creating a rain shadow.
3. 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?
In the oceans and seas
Salty ocean water accounts for roughly 97% of Earth’s total water.
4. Does the water cycle create brand-new water or continuously recycle the same water molecules through different states?
Continuously recycles the same water molecules
The hydrologic cycle is a closed system that circulates water between reservoirs.
5. Where is most of Earth’s fresh water locked up: in glaciers and polar ice caps, or in clouds?
In glaciers and polar ice caps
Around two-thirds of Earth’s fresh water is frozen in ice sheets and glaciers.
6. When spring temperatures warm mountain snowpacks, the resulting liquid water flowing into streams is called: snowmelt runoff or condensation?
Snowmelt runoff
Seasonal snowmelt feeds rivers and reservoirs in spring.
7. 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?
It cools, condenses and drops rain on the windward side
Orographic (relief) lifting cools rising moist air, causing condensation and rainfall.
8. What energy source drives the global water cycle by warming ocean and land surfaces: the Sun or the Moon?
The Sun
Solar radiation provides the thermal energy for evaporation and transpiration.
9. What stage of the water cycle occurs when rising water vapour cools high in the atmosphere and forms tiny cloud droplets: condensation or infiltration?
Condensation
Cooling causes water vapour to condense into liquid droplets or ice crystals.
10. 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?
Snow
Snowflakes form by deposition of water vapour onto ice crystals in clouds.
11. 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?
Faster
Greater surface area, higher temperature and air movement all increase evaporation rate.
12. What do we call the process by which rainwater soaks downward into soil and porous rock layers: infiltration (percolation) or evaporation?
Infiltration (percolation)
Infiltration replenishes soil moisture and underground aquifers.
