Question
Answer
What two features are used to classify clouds?   shape and altitude  
🗑
Name the three basic forms of clouds.   stratus, cumulus, cirrus  
🗑
What are the three altitude groups of clouds and their heights.   low clouds- 0-2000m (0 - 2 km) middle clouds- 2000-6000m (2km- 6 km) high clouds 6000m plus (6 km plus)  
🗑
feathery clouds composed of ice crystals   cirrus  
🗑
middle-altitude clouds that usually produce little precipitation   altostratus clouds  
🗑
high, dark storm clouds   cumulonimbus clouds  
🗑
clouds that form a high transparent veil   cirrostratus clouds  
🗑
billowy, low altitude clouds (that can change into higher altitude layers with updraft winds)   cumulus clouds  
🗑
clouds with a flat base forming at very low altitudes   stratus clouds  
🗑
Clouds that form where a layer of warm, moist air lies above a layer of cool air are called   stratus  
🗑
What do the prefix "nimbo" and the suffix "nimbus" mean?   rain  
🗑
the first stage of a thunderstorm, in which warm, moist air rises and water vapor in the air condenses to form a cumulus cloud   cumulus stage  
🗑
electricity that is discharged during a thunderstorm   lightning  
🗑
an effect created when electricity heats the air, and the air expands rapidly   thunder  
🗑
a usually brief, heavy storm that consists of rain, strong winds, lightning, thunder   thunderstorm  
🗑
the third stage of a thunderstorm, in which strong downdrafts stop air currents from rising and the storm dies out as water vapor decreases   dissipating stage  
🗑
the second stage of a thunderstorm, in which condensation continues as the cloud rises and becomes a dark cumulonimbus cloud, perhaps producing torrential rain and hail   mature stage  
🗑
What is condensation nuclei?   (also known as cloud seeds) are small particles on which water vapor condenses. Water requires a non-gaseous surface to make the transition from a vapor to a liquid; this process is called condensation.  
🗑
A destructive, rotating column of air that has very high wind speeds and may be visible as a funnel-shaped cloud   tornado  
🗑
A severe storm that develops over tropical oceans and whose winds of more than 120 km/h spiral in toward intensely low-pressure center   hurricane  
🗑
Be able to draw a diagram of a cumulonimbus cloud forming hail    
🗑
