The water cycle & freshwater

Answers and reasoning. Review before teaching.

1. When ocean water evaporates into the air, does the dissolved salt evaporate with the water vapour or stay behind in the sea?
Stays behind in the sea
Only pure water molecules evaporate; dissolved salts remain in the ocean, which is why rain is fresh water.
2. What happens to river discharge shortly after heavy rainfall in its drainage basin: river flow increases, or river flow stops?
River flow increases
Runoff and throughflow reach the river channel, raising its discharge.
3. 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.
4. 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.
5. 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.
6. 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.
7. 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.
8. What do we call the upper level of underground rock or soil that is completely saturated with groundwater: the water table or the treeline?
Water table
The water table marks the top of the groundwater saturation zone.
9. 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?
Watershed (drainage basin)
A watershed or drainage basin collects all runoff feeding a river network.
10. What stage of the water cycle occurs when liquid water at the ocean surface warms and turns into water vapour: evaporation or precipitation?
Evaporation
Evaporation changes liquid surface water into atmospheric water vapour.
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?
Precipitation
Precipitation returns water from the atmosphere to Earth’s surface.
12. What combined term describes the total water vapour transferred to the atmosphere from both soil evaporation and plant transpiration: evapotranspiration or precipitation?
Evapotranspiration
Evapotranspiration combines surface evaporation and plant transpiration.
