The Water CycleSlide3
Today’s Focus:
PrecipitationPrecipitation is water falling from the clouds.In the air, water vapor condenses around tiny particles, like dust, forming cloud droplets and clouds.As these droplets combined
and become larger they begin to fall to the Earth.Slide4
Types of Precipitation
There are four types of Precipitation…
Can you name them?
(Remember to RAISE YOUR HAND!)
Rain
Snow
Sleet
HailSlide5
R
ain occurs when drops of water fall to Earth in ABOVE freezing temperatures.Snow occurs when the air temperature is so cold that water vapor changes directly to a solid.
Sleet occurs when rain passes through a layer of freezing air near Earth’s surface forming ice pellets.
Hail occurs in cumulonimbus clouds of a thunderstorm when water freezes. Hail grows as it is tossed up and down within the cloud. It can be as large as a softball.Slide6
