These clouds are formed below 6,000 ft. These can mean a rainy day. These clouds are usually gray and look like flat sheets that take up most of the sky.
What is a stratus cloud?
100
When a warm air mass is replacing a cold air mass.
What is a warm front?
100
An extremely large body of air whose properties of temperature and moisture content (humidity), at any given altitude, are fairly similar in any horizontal direction.
What is an air mass?
100
A natural hazard is a threat of a naturally occurring event that will have a negative effect on people or the environment. Many natural hazards are interrelated, example earthquakes can cause tsunamis and drought can lead directly to famine or population displacement.
What is a natural disaster?
100
This is caused by heavy moisture in the air. Water evaporates, Water freezes to create clouds, Water droplets form, Water droplets in the clouds get heavy, Water droplets fall depending on how cold it is, water can freeze or partially freeze on the way down.
What is precipitation?
200
These clouds are mostly made above 18,000 ft. These clouds are thin because there is not a lot of water vapor above 18,000 ft so big clouds cannot form.
What is a cirrus cloud?
200
When a cold air mass is replacing a warmer air mass.
What is a cold front?
200
The pressure exerted by the atmosphere.
What is air pressure?
200
The basic ingredients used to make this natural disaster are moisture, unstable air and lift. You need moisture to form clouds and rain. You need unstable air that is relatively warm and can rise rapidly. Finally, you need lift. This can form from fronts, sea breezes or mountains.
How do thunderstorms form?
200
Water released from clouds in the form of rain, freezing rain, sleet, snow, or hail. It is the primary connection in the water cycle that provides for the delivery of atmospheric water to the Earth. Most this falls as rain.
How does precipitation form?
300
These clouds are formed alone and there is always a lot of distance between these clouds. These clouds look like fluffy balls of cotton and are also below 6,000 feet. The weather is normally nice but they can turn into thunderheads.
What is a cumulus cloud?
300
This front often brings several days of cloudy, wet weather that can last a week or more.
What is a stationary front?
300
It’s an air mass that forms over land or water in the higher latitudes.
What is a polar air mass?
300
By an earthquake, submarine landslide, or other disturbance.
How is a tsunami formed?
300
Rain, snow, hail, and sleet.
What are the different types of precipitation?
400
Produces steady rain, Forms under 6,000ft, Rain lasts for hours, Thick so you can't see the sun behind them.
What is a nimbostratus cloud?
400
This front forms as the cold air behind the cold front meets the cold air ahead of the warm front.
How does an occluded front form?
400
An air mass that forms in the tropics or subtropics over the low latitudes.
What is a tropical air mass?
400
This natural disaster forms through an exchange of warm, humid air and cold, unstable air between the upper and lower atmosphere.
How does a hurricane form?
400
A form of precipitation consisting of ice pellets, often mixed with rain or snow.
What is sleet?
500
Forms between 6,000 and 20,000ft, clouds look like puffy grey balls or blobs , usually darker than the rest.
What is a altocumulus cloud?
500
This front is represented by a solid line with semicircles pointing towards the colder air and in the direction of movement. On colored weather maps, a warm front is drawn with a solid red line.
How are warm fronts represented on the map?
500
Continental Arctic (cA), Continental polar (cP), Maritime polar (mP), Maritime tropical (mT), Continental Tropical (cT).
What are the five basic types of air masses?
500
Common causes of this natural disaster includes lightning, human carelessness, arson, volcano eruption, and pyroclastic cloud from active volcano. Heat waves, droughts, and cyclical climate changes such as El Niño can also have a dramatic effect on the risk of this natural disaster. Although, more than four out of every five of these natural disasters are caused by people.
How causes a wildfire?
500
This begins in the atmosphere as water condenses into a tiny droplet. As more and more water vapor condenses onto its surface, the droplet grows. Cold air then freezes this water into an ice crystal.
