Masses of tiny droplets of ice crystals or water
droplets
Part of the water cycle
Clouds are made up of billions of water droplets
or ice crystals and sometimes both.
Form when water vapor in the air
condenses(CONDENSATION)
When water vapor condenses ,it changes to
liquid water
Formation starts when warm air rises
(EVAPORATION)
Warm air near Earth’s surface holds water vapor
As warm air rises, it moves into the cooler parts
of the atmosphere
Cool air cannot hold as much water vapor as
warm air
Some of the water vapor condenses around tiny
pieces of dust in the air
Tiny droplets of liquid water form.
If the air is very cold, the water vapor forms ice
crystals

Indicate good weather
Higher than stratus but lower than cirrus
Often spread out
Large spaces of blue sky in-between
Sometimes become big and dark
(cumulonimbus
Bring rain, thunder, and lightening
Can’t hold all their water droplets
The rain drops are so heavy that they can turn
in to Rain, Snow, or hail
The Clouds tall, puffy, and Gray
Often call “Storm Clouds”
Nimbostratus Clouds
Nimbostratus clouds form at or below 6,000 feet.
They are dark, low level clouds that bring light to moderately
heavy precipitation, such as snow or rain.
These clouds, although low in the atmosphere, may contain ice
crystals when the temperatures get below the freezing point.
Below nimbostratus clouds can lie broken up clouds that are
called fractostratus clouds.
Altocumulus clouds
Altocumulus clouds
are made of water
droplets and
appear as gray
puffy masses. They
usually form in
groups. If you see
altocumulus clouds
on a warm, sticky
morning, be
prepared to see
thunderstorms late
in the afternoon.
Stratus clouds are uniformed
layered clouds that are below
6,000 feet. They are formed in
sheets and are usually
associated with overcast
weather. Fog or mist is the
result of very low stratus
clouds. They can form only a
few hundred feet above
ground. They are shallow but
cover a large area, and they
can bring precipitation. Stratus
clouds are more known for
drizzle than for precipitation,
however. When heavier rain
falls from them, their title is
changed to nimbostratus
clouds. Stratus clouds are
formed when a weak upward
air current lifts a thin layer of
air high enough to start
condensation of the excess
water vapor if the air
temperature falls below the
dew point.
Stratus
Altostratus clouds
appear in altitudes of
6,000 to 20,000 feet.
They are very thin and
uniform, and are gray or
blue-gray, creating
overcast. They are
translucent enough to
see the sun or moon
through them, however
they do not allow
enough light to make
shadows on the Earth’s
surface. Altostratus
clouds are associated
with coming rain, and
they usually cover most,
if not all, of the sky.
Altostratus clouds are
incapable of producing
heavy precipitation, but
they are often the cause
of a light drizzle.
Following altostratus
clouds are nimbostratus
clouds, which are the
source of heavier
precipitation.
Altostratus Clouds
Stratocumulus clouds
Stratocumulus clouds
are low puffy gray
clouds. Most form in
rows with blue sky
visible in between
them. Rain rarely
occurs with
stratocumulus clouds,
however, they can
turn into
nimbostratus clouds
Fog can be created when warm moist air is over
cold ground or soil. Fog is a very dangerous
thing on the road it can be a visibility of O%.
Fog is not usaully counted as a cloud because of
how it is created. Clouds are created by
condensation and fog is created by warm moist
air.
Cirrus look like wispy little feathers and are
made from tiny ice crystals
Cirrus clouds form when there is cool air in the
atmosphere
If you happen to see these clouds their may be
a chanced that you will see rain in the next 4872 hours
Cirrus clouds are located about 600m or 20,00 ft
in the air
These clouds usually move east to west
Cirrocumulus clouds are small rounded clouds
That are usally found around winter
These clouds usually have small ripples that
represent fish scales
Some people have nicknamed these clouds “
mackerel sky clouds”
These clods are in the sky about 500-1300ft in
the air
They can come in shades of white or gray
Cirrostratus is a milky color clod made out of ice
crystals and it sometimes looks like a small halo
appearance around the sun or moon
When you see these clouds you can expect to
see rain from 8-24 hours
Although you might see rain their may be a
chance you’ll see snow
These clouds allow the sun or moon to shine
through them
What are the 3 main
types of clouds?
1. Cirrus
2. Cumulus
3. Stratus
Where do cirrus
clouds form?
They form above 18,000 feet.
What do
cumulus clouds
indicate?

clouds you know it will
rain within ___ and __
hours
