Water Cycle
Question | Answer |
---|---|
___________ is always moving between the atmosphere (troposphere) and the surface of Earth. | water |
After condensation occurs (forming clouds), water droplets fall in various forms of ______________________ – rain, snow, freezing rain, sleet, hail, depending on weather conditions. | precipitation |
Two things determine what type of precipitation will fall: a. _______________________________________________ b. ________________________________________________ | temperatures within clouds; temperatures between the clouds and the ground |
Water enters the atmosphere as water vapor through ____________________ and ____________________ . | evaporation ; transpiration |
_______________________is the process of liquid water changing into a gas. | evaporation |
____________________ is the process of plants losing excess water through their leaves. | transpiration |
___________________ happens in the atmosphere as water vapor changes to water droplets. | condensation |
_________________________ as a result of condensation. | clouds form |
____________ and ______________are also a result of condensation. | dew; frost |
_____________ forms when water vapor condenses directly onto a surface. | dew |
______________ forms when water vapor changes from a gas directly into ice crystals on a surface. | frost |
There are two types of run-off: ___________________________ and ______________________________. . | surface-water flow ; ground-water flow |
________________________________________ is when water will remain on the surface when the surface is not porous or the precipitation is falling too fast for the water to sink into the ground. | surface-water flow |
________________________________________ is when water will sink into the ground when the surface is porous and there is lots of space in the soil to hold the water. | ground-water flow |
_____________ is the driving force for precipitation and the downhill flow of water on land. | gravity |
____________________is the physical process moving water through the layers of soil. | infiltration |
________________is a water-bearing rocks transmitting water to wells and springs underground. Precipitation eventually adds water (recharging) into the porous rocks of the _____________. | aquifer |
