Weather Maps & Fronts
100
The variable that tells us how hot or cold the air is.
What is temperature?
100
This type of air rises because it is lighter and less dense.
What is warm air?
100
This type of pressure is usually linked to sinking air and clear skies.
What is high pressure?
100
Wind is caused when air moves from this pressure area to another type of pressure area.
What is from high pressure to low pressure?
100
This blue symbol on a weather map shows an area of sinking air and usually clear weather.
200
This variable measures how much water vapor is in the air.
What is humidity?
200
This type of air sinks because it is heavier and more dense.
What is cool air?
200
This type of pressure is linked to rising air, clouds, and rainy weather.
What is low pressure?
200
This uneven natural process is the main reason pressure differences form on Earth’s surface.
What is the sun's heating of Earth's surfaces?
200
This red symbol on a weather map shows an area of rising air that often brings clouds and rain.
300
This variable is the weight of the air pressing down on Earth.
What is air pressure?
300
When warm air rises, this type of pressure is created at the surface.
What is low pressure?
300
Air always moves from this type of pressure area toward the other type.
What is high pressure to low pressure?
300
Warm air rises and cool air sinks, creating this type of cycle that helps drive wind.
What is convection?
300
These lines on a weather map connect places with equal air pressure.
Isobars
400
This variable describes air moving from high pressure to low pressure.
What is wind?
400
When cool air sinks, this type of pressure forms at the surface.
What is high pressure?
400
When air sinks in a high-pressure area, clouds usually do this.
What is disappear (or clear out)?
400
When one area is heated more than another, this weather variable changes and helps generate wind.
What is air pressure?
400
This type of front moves quickly and often causes short, intense storms.
Cold front
500
This variable includes rain, snow, sleet, or hail falling from the sky.
What is precipitation?
500
This process happens when warm air rises and cool air sinks, driving many weather patterns.
What is convection?
500
This pressure condition often creates strong winds when the difference between two nearby areas is very large.
What is a steep pressure gradient?
500
______ ______ , when large, cause wind speeds to increase quickly and become stronger.
What are pressure gradients (pressure differences)?
500
This weather map shows very tightly packed isobars around a low-pressure system. What does this tell you about the wind in that area? 
The wind will be strong (or fast)
501
FINAL JEOPARDY CATEGORY
WIND
501
This single factor begins the chain reaction that creates differences in air pressure and leads to wind.
Uneven heating of the Earth's surfaces
