ARE CLOUDS FORMED?
Humidity is the amount of
moisture in the air. When it is
humid out, you feel sticky, your
glasses can fog up, and your hair
can frizz. When water is
warmed by the sun, it
evaporates into the atmosphere.
As the water vapor rises, it
(CCC) Cools, Condenses, and
forms a Cloud.
Warm air is pushed up a
mountain (warm air rises)
Water cycle
When cold air and warm air
meet, the cold air pushes the
warm air out of the way (warm
air rises)
D40
STRATUS CLOUDS
⦿ Blanket
like layers
⦿ Long lasting storms
⦿ Small raindrops
CIRRUS CLOUDS
⦿ High
in the
atmosphere
⦿ Made of ice
crystals
⦿ Wispy and feather
like
⦿ Snow
CUMULOUS CLOUDS
⦿ Puffy
and rise up
from a flat bottom
⦿ Heavy rain last for
a short period of
time (downpour)
CUMULONIMBUS CLOUDS
Rain or storms
⦿ Gray or black
⦿ Vertical (develop
upward)
⦿ Thunderstorms that can
also lead to tornadoes
⦿ Larger raindrops
⦿ Hold a lot of water
⦿ Turbulent (violent)
⦿ Can reach high altitudes
⦿ Downpours
⦿ HAIL
⦿
FOG
⦿ ground
level
⦿ moist air at ground
level cools
WHY AND WHEN DOES IT PRECIPITATE?
⦿ When
the cloud fills up with too much water
and it cannot hold anymore water, the cloud
releases the water.
⦿ This releasing of water is called
precipitation.
