Water Cycle Notes

Lesson Notes• Hydrosphere: liquid (water) layer of the Earth (e.g., oceans,

lakes, rivers, streams, glaciers?)• Atmosphere: gas layer of the Earth• Lithosphere: solid (rock) layer of the Earth (= crust +

uppermost mantle)

• Cloud Formation: warm air (humid/moist, carries water), rises; why? less dense, cools with altitude;

water vapor (gas) → tiny water droplets (liquid) [process: condensation] attach onto condensation nuclei, clouds form

• Cloud Types: cumulus = puffy; cirrus = high altitude, feathery, wispy clouds (lowermost stratosphere); cumulonimbus = chimney-like puffy rain clouds (cold front, heavy downpour); nimbostratus = layered rain clouds (warm fronts, slow drizzle)
