Air Pressure, density and temperature

The pressure exerted by the weight of air is called

• atmospheric pressure

• atmospheric temperature

• altitude

• density

Atmospheric pressure increases (gets bigger) as altitude increases (the higher up you go)

• true

• false

which layer of the atmosphere has the most pressure?

• thermosphere

• mesosphere

• stratosphere

• troposphere

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 pressure increases, density...

• decreases

• stays the same

• increases

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

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.
