How do cumulonimbus clouds affect weather?
Cumulonimbus clouds produce rain and thunderstorms.
What is the study of clouds called?

What's a cloud?
a mass of water droplets or ice crystals suspended in the atmosphere
What does a cloud need to form?
A cloud needs water vapor, cool air, and condensation nuclei to form.
What are cumulus clouds? (what does cumulus mean)
heap or pile; puffy lumpy, piled cloud shape
How do cumulus clouds affect the weather?
Cumulus clouds cause fair weather.
Who was Luke Howard?
Luke Howard is the person who created the cloud classification system.
What's the definition of hail?
ice pellets that form from supercooled liquid interactive with updrafts
In the cloud formation process, the heats up and surfaces.
In the cloud formation process, the sun heats up water and land surfaces.
Fill in the blanks for alto- level for clouds, prefix for clouds in between and feet
How do altocumulus clouds affect weather?
Altocumulus clouds cause precipitation to come along the way.

What's the definition of aerosol?
solid or liquid particles suspend in a gas
What does water vapor need to do for a cloud to form?
It needs to and into or .

What are stratus clouds? (what does stratus mean)
layer or sheet; layered, flat cloud shape
What can nimbostratus clouds lead to and turn into?
Nimbostratus clouds can cause precipitation and can turn into cumulonimbus clouds.
Fill in the blanks for snow-Snow is small white of ice formed directly from of the air
Snow is small white crystals of ice formed directly from the water vapor of the air.
What is condensation nuclei?
solid or liquid particles that trigger condensation which allows cloud formation to occur
How do clouds form?
Water vapor needs to be cooled and condensed into liquid water droplets or ice crystals. These water droplets/ice crystals form on tiny particles (condensation nuclei ), similar to dust, that are floating in the air
Fill in the blanks for cirro- level for clouds, prefix for clouds above feet
highest level for clouds, prefix for clouds above 20,000 feet
What weather do stratus clouds cause?
Stratus clouds can cause light rain, or they might end up as fog.
How do clouds stay in the air? (3 main reasons)
Clouds stay in the air because...
- updrafts keep the air aloft
- water droplets and ice crystals are so small that they can float in the air for a long time before falling (similar to dust)
- Clouds are warmer than the surrounding air, making them less dense, so they rise/stay aloft. Heat is released when condensation occurs, and that's what keeps the cloud warm.
