(34 cards)
Clouds form from
Water vapor
Water vapor particles rise up and
Lose heat energy.
As clouds become colder, they
Lose speed and cuddle up.
The water vapor particles condense around tiny particles of dust to form clouds when
The water vapor particles slow.
The appearance of a cloud depends on
- How high it forms
2. What the temperature is
Cirrus clouds form
At the highest altitudes.
Cirrus clouds are formed from
Ice crystals when liquid is cooled at 0 degrees C or 32 degrees F.
Cirrus clouds appear
Fuzzy and wispy.
Cumulus clouds are formed at
Middle altitudes.
Cumulus clouds appear
Puffy.
Stratus clouds are formed at
Low altitudes.
Stratus clouds appear
Layered.
Lower clouds form from
Water droplets.
Lower clouds appear
Gray and black.
Why do lower clouds appear this way?
They are so dense the sun can’t pass through.
Fog is
A thick mist.
When does fog form?
When the temperature near the ground is cold.
Clouds in the air contain
Water droplets.
When do clouds become thick and gray?
When the droplets collide.
When do the drops from the clouds fall to the ground as precipitation?
When they become heavy.
What is liquid precipitation?
Rain
What forms when the air temperature is below the freezing point of water?
Solid precipitation
What are the three types of solid precipitation?
Hail, sleet, and snow
When does hail form?
In severe thunder storm clouds.
