8th_U1-L4_Study Set_Air Pressure & Wind

What direction do air particles move to create wind?

• High pressure-> Low pressure

• Low pressure-> High pressure

• High pressure-> High pressure

• Low pressure-> Low pressure

In a high pressure system...

• particles are close together

• particles are far apart

• there are no particles

• the particles are moving very fast

As you go up in altitude, air pressure...

• increases

• decreases

• stays the same

If there is a high pressure system over Minnesota and a low pressure system over Missouri, which direction will wind be blowing in Iowa?

• North

• South

• East

• West

As pressure increases, density...

• decreases

• stays the same

• increases

As you go up in altitude, density...

• increases

• decreases

• stays the same

If the air is cold, what does that tell you about the air pressure and density?

• Air pressure and density are both high

• Air pressure and density are low

• Air pressure is high but density is low

• Air pressure is low but density is high

This is the reason why hot air particles rise:

• They are less dense than cold air

• They are more dense than cold air

• They a traveling very slowly

• They are undergoing a state change from a solid to a liquid

What is an example of convection?

• Hot air rising and cold air sinking

• Hot air sinking and cold air rising

• Touching a hot stove and getting burned

• Feeling the sun's rays as warmth

Why do low pressure systems often result in cloudy days?

• The air rises and the water vapor condenses into clouds

• The air sinks to the earth's surface and water vapor condenses into clouds

• Low pressure systems actually bring clear skies

• There is no wind on a low pressure day
