Types of Clouds
*Clouds are classified by
their shapes and by the
altitude at which they form.
cirrus
cirrus
Thin, wispy clouds
that form high in the
sky. These form
when the wind is
strong.
cumulus
cumulus
Fluffy, white clouds that
look like piles of cotton
balls with flat bottoms.
These form as warm air
rises and are usually a
sign of fair weather.
stratus
stratus
Flat, horizontal clouds that form in
layers and at low altitudes.
These form when a large mass of
air is gently lifted into the
atmosphere. They tend to cover
large areas of the sky and block
out sunlight.
cumulonimbus
cumulonimbus
These are large
cumulus clouds that
bring thunderstorms.
