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)
Warm
increasing altitude
Cold
HOW DO CLOUDS FORM
Condensation nuclei
pollen, volcanic ash, pollution =
Water vapor gas → tiny moisture droplets
Precipitation
Warm Front Clouds
Cold Front Clouds
Cumulonimbus Clouds
Cumulonimbus (thunderstorm) Clouds
Cirrus Clouds =
wispy, feathery
high altitude
lower Stratosphere
Fog = Cloud on the ground
