• A mixture of gasses that surrounds the planet.

• 2nd layer of the atmosphere

• The measure of force with which air molecules push on a surface.

How does temperature change with elevation in the troposphere?

• As elevation increases, temperature decreases

• As elevation increases, temperature increases

• As elevation stays the same, temperature decreases

• None of these

What would happen to air pressure if you hike down a mountain

• Air pressure increases

• Air pressure decreases

• Nothing happens

• None of these

The ozone layer is found in this layer of the atmosphere

• Troposphere

• Thermosphere

• Mesosphere

• Stratosphere

The atmosphere is mostly made up of this gas.

• Oxygen

• Nitrogen

• Argon

• Water Vapor

The ozone layer is important because....

• It gives us water

• It gives us light

• It absorbs harmful radiation

• It causes the seasons

Low pressure systems cause....

• Clear and dry condidtions

• Stormy weather

• The water cycle

• None of these

Weather occurs in the troposhpere

• True

• False

As temperature goes up what happens to air pressure

• It goes up

• It stays the same

• It goes down

• Non of the above

A barometer measures....

• Air temperature

• Air quality

• Air pressure

• Wind speed
