The maps above show a front as it moves east across the United States. Which of these describes the weather change that can be expected for Amarillo, Texas?
The cold front will bring cooler temperatures and snow because the cold front is producing large amounts of energy and snow moving southeast.
The cold front will bring cooler temperatures with thunderstorms and rain, which causes the moisture in the warm air to condense and release large amounts of energy.
The warm front will bring warmer temperatures with hot air for several days because it pushes the cold air out of the way.
The warm front will bring warmer temperatures with light rain for a few days because the warm air rises and cools producing rain.
Cold air is denser than warm air, so it sinks. What kind of pressure area does this create?
Dense pressure
High pressure
Low pressure
No pressure
Which of the following increases air’s ability to hold water vapor?
Increase in wind speed
Decrease in temperature
Increase in temperature
Decrease in air pressure
In some years there are more hurricanes than usual. This is probably because

high pressure and low humidity
high pressure and high humidity
low pressure and low humidity
Air becomes wind as it flows from...
low pressure to high pressure.
high pressure to high pressure.
low pressure to low pressure.
high pressure to low pressure.
What does low pressure usually mean for weather?
It will be sunny because cold air is sinking.
It will be cloudy because cold are is sinking.
It will be sunny because are air is sinking.
It will be cloudy because warm air is rising.
What does high pressure usually mean for weather?
It will be sunny because cold air is sinking.
It will be cloudy because cold are is sinking.
It will be sunny because are air is sinking.
It will be cloudy because warm air is rising.
Why does a HIGH pressure system usually bring dry, clear skies?
The air is warm, less dense, rises and moves so fast it doesn't have time to make clouds.
The air is cold, more dense and sinks. There is no water vapor rising to make clouds.
The air is warm, more dense and sinks. There is no water vapor rising to make clouds.
Why does a LOW pressure system usually bring cloudy and often stormy weather?
The air is warm, less dense, rises and moves so fast it doesn't have time to make clouds.
The air is cold, more dense and sinks. There is no water vapor rising to make clouds.
The air is warmer and less dense. It rises and the water vapor condenses to make clouds.
What causes wind?
Air moving from ares of HIGH density to areas of LOW density.
Air moving from areas of LOW density to areas of HIGH density.
Gnomes. It's always the gnomes!
Which of the following does NOT directly affect weather?

Why would clouds form when warm and cold air masses collide?
