How many air masses are there? 

What are four air masses? 
100
This air mass forms over northern Canada?
What is a Continental Polar (cP) air mass
100
Place where two or more air masses meet?
What is a front
100

Condensation and Precipitation of THUNDERSTORMS are part of this

What is the water cycle?

100

These people observe many patterns of weather change to make weather predictions. 

What are weather forecasters? 

200
a very large volume of air that has a certain temperature and moisture content
What is an AIR MASS
200
Form over deserts and bring clear, dry, and hot weather in the summer
What is Continental Tropical (cT) air mass
200
forms when a warm air mass moves in over a cold air mass leaving an area
What is a warm front
200

Three types of severe weather that we discussed

What are Thunderstorms, Tornadoes, and Hurricanes?

200

This kind of air pressure brings clear skies.

What is High Pressure?

300

What are the properties of an air mass?


What is by the amount of water and temperature of the air

300
These air masses are cool and very wet?
What is Maritime Polar (mP) air mass
300
Move quickly and bring heavy precipitation
What is a cold front
300

an alert that means severe thunderstorms with high winds and hail might form 

What is a severe thunderstorm watch?

300

This kind of air pressure brings fronts.

What is low air pressure? 

400

What causes air masses to move? 

What is wind

400
Bring heat, humidity, hurricanes, and thunderstorms across the East Coast and into the Midwest
What is Maritime Tropical (mT)
400
In this front, neither air mass has enough energy to push the other out of the way.
What is a Stationary Front
400

An alert that means severe thunderstorms have formed and you should prepare for them. Get inside as soon as possible. 

What is a severe thunderstorm warning? 

400

The average of weather conditions over a long time.

What is climate? 

500

What might happen if an air mass from Canada moves into the middle of the USA? 

What is a storm

500
These bring extremely cold winter weather and cool dry weather in the summer
What is Continental Polar (cP)
500

Where in the front is there lower air pressure?

What is at the front of the front?

500

What is the difference between a tornado and a hurricane? 

Tornadoes form on land. Hurricane on water. 

Tornadoes are only hundreds of meters across. Hurricanes can be hundreds of kilometers. 

Tornadoes last a few minutes. Hurricanes last several days. 

Tornadoes have much faster winds. 

500

These affect a climate by slowing the rise and fall of the air temperature. 

What are oceans?
