Low Clouds | Middle Clouds | High Clouds | Cloud Formation |
---|---|---|---|
Stratus Clouds
What is the name given to clouds that are layered in appearance and blanket the lower atmosphere?
|
Alto
What prefix is associated with middle clouds?
|
ice crystals
What is the main form of precipitation that exists in high atmosphere clouds?
|
salt, dust, ash
Cloud condensation nuclei, also known as aerosol particles, can be made up of what?
|
Stratus, Stratocumulus and Nimbostratus
What are the three most common kinds of clouds found in the lower atmosphere?
|
Altocumulus and Altostratus
What are the two most common clouds seen in the middle atmosphere?
|
cirrus clouds
These clouds are blurry and wispy in appearance due to their low water content and cold temperatures.
|
10 micrometers
Clouds form and are made up of cloud droplets. What is the typical radius of a cloud droplet?
|
Light precipitation
What type of precipitation do nimbostratus clouds yield?
|
Altocumulus clouds
What kinds of clouds form long bands or contain a series of puffy rows?
|
halo clouds
These clouds form when light interacts with ice crystals suspended within clouds high in the atmosphere.
|
aggregation
What is it called when many ice crystals join together to create one large crystal?
|
Stratus Clouds
Which kinds of clouds in the lower atmosphere are normally between 0.5 and 1 km thick, and can span across several states horizontally?
|
Heights between 2000 and 6000 meters
In meters, middle clouds are found between which heights of the atmosphere?
|
a contrail
Name this type of ice cloud, found in the higher atmosphere, that is frequently caused by jet aircrafts.
|
collision-coalescence
In warm clouds, large droplets called collector droplets have high terminal velocities. As they fall, they collect smaller droplets onto them and create one large rain drop. What is this process called?
|
2000 meters
What height (in meters) separates low and middle clouds?
|
Altocumulus
While this cloud is predominantly formed of water droplets, low temperatures in the winter cause ice crystals to form and make up the whole cloud. What kind of cloud forms like this?
|
The clouds condense and freeze, or nucleate, on very specific mineral and metal particles high in the atmosphere
How do cirrus clouds form?
|
The Bergeron Process
What is it called when molecules of water evaporate into the air and then deposit directly onto ice crystals?
