Meteorology Review

What percent of our atmosphere is made up of gases other than oxygen and nitrogen?

• 5%

• 10%

• 2%

• 1%

As you rise upwards in the atmosphere, air pressure

• increases

• decreases

• doesn’t change

• first increases, then decreases

Cool air tends to

• less dense and flow over warm air

• be lifted up by more dense warm air

• be more dense and flow under warm air

• mix easily with warm air masses

The eye of a hurricane

• has the highest winds

• has dense clouds

• produces the storm surge

• is calm

Which layer of the atmosphere protects Earth’s surface from being hit by most meteoroids?

• troposphere

• stratosphere

• thermosphere

• mesosphere

What is the layer of the atmosphere in which weather occurs?

• troposphere

• exosphere

• stratosphere

• mesosphere

Heat from the sun reaches you by

• radiation

• conduction

• light emission

• convection

When climbing a high mountain, you get out of breath easily because

• the percentage of oxygen in the air decreases

• air pressure is greater

• the air is more dense

• there is less oxygen in each cubic meter of air

- Lowest layer.

- Weather occurs here and therefore clouds.

- We live in it.

• mesosphere

• troposphere

• stratosphere

• thermosphere

- Contains the ozone layer

- The ozone layer protects the surface from dangerous UV rays (ultraviolet radiation from the Sun).

• Troposphere

• Stratosphere

• Exosphere

• Thermosphere
