Clouds
4.E.2B.1 Analyze and interpret data from observations,
measurements, and weather maps to describe patterns in local
weather conditions (including temperature, precipitation, wind
speed/direction, relative humidity, and cloud types) and predict
changes in weather over time.
How do Clouds Form?
• The formation of clouds happens when
water vapor in the air rises, cools and
condenses (or moves from a warm place
to a cool place and condenses), forming
the water droplets that make up a cloud.
What is a Cloud?
• A cloud is a collection of tiny, liquid
water droplets not water vapor gas.

bring rain; white cumulus clouds do not
bring rain
 They are usually associated with fair
weather.
Cumulus Clouds
Cirrus Cloud
 High, thin, wispy clouds.
 They are formed mostly of ice crystals.
 They often indicate a change in the
weather that is coming.
Cirrus Clouds
Stratus Cloud
 Layers of clouds that spread out covering
a large area.
 Stratus clouds are often lower in the sky
and are typically gray.
