Atmosphere Review

Increases carbon dioxide may cause global warming by...

• allowing more sunlight into the atmosphere.

• reflecting more sunlight from clouds.

• reducing the amount of oxygen in the air.

• absorbing more heat in the atmosphere.

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

• Troposphere

• Stratosphere

• Mesosphere

• Thermosphere

The layer of our atmosphere in which weather occurs is the

• Troposphere

• Stratosphere

• Mesosphere

• Exosphere

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

Convection takes place because

• warm air is more dense than humid air.

• warm and cold air have the same density.

• cold air is less dense than warm air.

• cold air is more dense than warm air.

Ozone is

• a form of oxygen with three oxygen atoms in each molecule.

• a form of nitrogen with three nitrogen atoms in each molecule.

• a form of oxygen with two oxygen atoms in each molecule.

• a form of nitrogen with two nitrogen atoms in each molecule.

The atmosphere is

• the layer in which weather occurs.

• the layer that contains the ozone layer.

• the layer of water in the oceans.

• the layer of gases that surrounds Earth.

The most abundant gas in the Earth’s atmosphere is

• Oxygen

• Hydrogen

• Carbon Dioxide

• Nitrogen

Earth’s rotation makes global winds curve. This is called the
