What is a weather front?

• A boundary between clouds and dry air
• A cluster of clouds
• A boundary between different air masses
• A type of weather disturbance

Hazardous weather is most often caused by

• Collision of different winds.
• Collision of low and high pressure areas.
• Collision of rain with snow.
• Collision of warm and cold air masses.

Close lines on an isotherm map are where:

• winds blows calmly
• where pressure change is the greatest
• temperature change is greatest
• temperature is lowest

What is a tornado?

• A violently rotating column of air.
• A large storm that forms over the ocean.
• Very strong winds that are damaging.
• A cluster of lighting strikes.

What is a blizzard?

• A snowfall of more than 12 inches.

• Any winter storm that gives dangerous driving conditions.

Winds blow from:

• Low pressure to high pressure.
• High pressure to low pressure
• Warm air to cold air.
• Cold air to warm air.

An isobar map shows:

• Lines of similar temperature.
• Lines of similar pressure.
• How regions have different air temperatures.
• Both A and B.

Close lines on an isobar map are where:

• Temperature change is greatest.
• Pressure change is greatest.
• Temperature change is least.
• Pressure change is least.

What is an isotherm map?

• A map that shows barometric pressure in a region.
• A map that shows the climate of a region.
• A map that shows elevations of a region.
• A map that shows the temperatures of a region.
