- 2. Multiple Choice
A meteorologist observes a decrease in air pressure and predicts a chance of light to moderate precipitation with warmer temperatures. Which frontal system is most likely approaching?
Cold Front
Warm Front
Occluded Front
Stationary Front
- 3. Multiple Choice
What is the best evidence to support that an occluded front is occurring?
A warm and cold front collide and remain motionless.
Cool air sinks and warm air rises, creating a convection current.
A cold front pushes warm air upward, and the cold front collides with a cold front.
A warm front pushes into the area, creating clear skies and warm weather.
- 4. Multiple Choice
Which result most likely occurs when cold and warm air masses collide?
The cold air mass pushes under the warm air mass.
The warm air mass pushes under the cold air mass.
The cold air mass and the warm air mass remain stationary.
The cold air mass and the warm air mass mix to create a new air system.
- 5. Multiple Choice
Which statement best describes the general movement of air?
They move from areas of high altitude to areas of low altitude.
They move from areas of high pressure to areas of low pressure.
They move from areas of high humidity to areas of low humidity.
They move from areas of low temperature to areas of high temperature.
- 6. Multiple Choice
On a warm day in late October, the air temperature drops 20 degrees and a rare fall thunderstorm takes place. Which event is most likely happening with the changes in weather?
There's a occluded front moving through
There's a warm front moving through
There's a cold front moving through
There's a stationary front moving through
- 7. Multiple Choice
Which choice best explains why a low-pressure system and a high-pressure system create different weather conditions?
