Total questions: 15
Worksheet time: 8mins
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
The atmospheric pressure is greatest when the air is...
Cold
Hot
Temperature does not affect pressure
How does the Coriolis Effect impact winds?
It is the reason that we perceive winds as traveling in a straight line.
It is the reason that we perceive winds as traveling in an arc.
It makes winds travel twice as fast.
It causes earthquakes.
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
In what direction does weather typically move across the United States?
North
South
East
West
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
How do we classify an air mass?
Based on where it formed
Based on where it is going
Based on its speed and direction
All air masses are identical
If land is a hot surface and the ocean is a cool surface, in which direction will the wind be blowing?
Towards land, because above the ocean would be high pressure air.
Towards land, because above the ocean would be low pressure air.
Towards the ocean, because above land would be low pressure air.
Towards the ocean, because above land would be high pressure air.
