Air Masses and Fronts Review

What happens to air pressure as altitude increases?

• Air pressure increases

• Air pressure stays the same

• Air pressure decreases

• Air pressure fluctuates randomly

Which of these best describes what creates air pressure?

• The weight of air molecules pushing down

• The temperature of the air only

• The movement of clouds

• The color of the sky

In a high-pressure system, air typically:

• Rises and creates clouds

• Moves sideways only

• Sinks and creates clear skies

• Stays completely still

What typically happens when a warm air mass meets a cold air mass?

• Nothing happens at all

• The warm air rises over the cold air

• The cold air rises over the warm air

• Both air masses stay in place

What happens when a warm front meets a cold air mass?

• The warm air sinks beneath the cold air

• The warm air rises gradually over the cold air
  

• The cold air immediately evaporates

• Both air masses remain separate and stationary

What symbol represents a warm front on a weather map?

• A blue line with triangles

• A red line with semicircles

• A purple line with both triangles and semicircles

• A black line with no symbols

How can you predict that a warm front is approaching?

• Increasing wind speeds and rapidly dropping temperatures

• Clear skies and rising air pressure

• Gradually lowering clouds and slowly falling air pressure

• Sudden thunderstorms and hail

What typically happens to air pressure when a cold front approaches?

• It remains constant

• It gradually rises over several days

• It drops suddenly, then rises sharply

• It rises and falls in a repeated pattern
