100

The air mass that slides over a cold air mass.

What is a warm air mass?

100

The mass that takes the place of a warm air mass. 

What is a cold air mass?

100

The occluded front passes by. 

What are clear skies?

100
The stopping of a cold and warm front. 

What is a stationary front?

100

The rising in the atmosphere? 

What is low pressure?

200

The warm, less dense air that moves over the colder denser air. 

What is a relatively stable atmosphere? 

200

The cold front passes.

What are gusty winds. 

200

The occluded front passes by. 

What is dry air?

200

The many days of rain during a stationary front. 

What are drizzles and fog?

200

The high pressure is associated with a specific air type.

What is sinking air?

300

The thunderstorms forming around the warm front.

What is unstable air? 

300

The lifted warm air ahead of the front. 

What is the production of clouds and thunderstorms?

300

The wind changes direction as the front passes.

What are cool and warm temperatures?

300

The two masses of air that push against each other, neither are powerful enough to move the other. 

What is the power of movement?

300

The air pressure is higher during high pressure.

What is air pressure pushing down on the ground?

400

The front passes over an area where the clouds become lower. 

What is the likeliness of rain? 

400

The production of dramatic changes in the weather.

What are the side effects of cold fronts?

400

The speed of cold fronts compared to warm fronts. 

What does it mean to overtake something? 
400

The blowing of winds parallel to the front help it stay in place rather than perpendicular. 

What are perpendicular lines?

400

The faster moving molecules that are unlikely to stick together due to high momentum. 

What are water molecules?

500

The stormy weather is often as the warm air mass at the surface rises above the cool air mass. 

What are clouds and storms and how are they made? 

500

The heavy rain, sometimes with hail thunder, and lightning. 

What is a sudden drop in temperature?

500

The precipitation along an occluded front. 

What is a cumulonimbus and/or nimbostratus  clouds. 

500

The stationary front marks the boundary between two air masses. 

What are often the differences in air temperature and the wind on opposite sides of it? 

500

The water molecules are most likely to stick together and the process continues for long periods of time resulting in different weather. 

What are the results of clouds and precipitation?
