02
Front
What is Earth’s largest water store?
Back
The ocean is Earth’s largest water store.
03
Front
What happens during evaporation?
Back
Evaporation changes liquid water into water vapor, mainly from oceans and other wet surfaces.
04
Front
How do changes of state connect water with snow and ice stores?
Back
Freezing, melting, and sublimation move water among liquid, solid, and vapor states, connecting it with snow and ice stores.
05
Front
How does solar energy drive the hydrologic cycle?
Back
Sunlight warms Earth’s surface and supplies energy for evaporation and plant transpiration.
06
Front
How is a water store’s change in storage calculated?
Back
A store’s change in storage equals the water entering minus the water leaving: Change in storage=water entering−water leaving.
07
Front
Which climate conditions influence where and when water moves?
Back
Temperature, precipitation, humidity, winds, and the timing of snow and ice melt influence where and when water moves.
08
Front
What is transpiration, and what is it called when combined with evaporation?
Back
Transpiration is the release of water vapor from plant leaves. Evaporation and transpiration together are called evapotranspiration.
09
Front
What happens during condensation?
Back
Condensation occurs when water vapor cools and becomes liquid droplets or ice crystals, forming clouds.
10
Front
What is precipitation?
Back
Precipitation is water falling from clouds as rain, snow, sleet, or hail.
11
Front
How do infiltration and percolation differ?
Back
Infiltration is water entering the soil; percolation is its movement deeper underground, which can replenish groundwater.
12
Front
Where do runoff and streamflow carry water?
Back
Runoff and streamflow carry water over land and through streams and rivers toward lakes, wetlands, or the ocean.
