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. ________________within clouds b. Temperatures between the clouds and the ______________. | temperatures within clouds; temperatures between the clouds and the ground |
| Water enters the atmosphere as water vapor through ______________ and _______________. | evaporation ; transpiration |
| Evaporation is the process of liquid water changing into a _______. | evaporation |
| __________________ is the process of plants losing excess water through their leaves. | transpiration |
| Condensation happens in the atmosphere as ____________________________________. | condensation |
| Clouds form as a result of _____________________.. | 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: surface-water flow and _____________________________ | surface water flow;ground water flow |
| Explain Surface 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. |
| _______________________ 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 |
