Atmosphere Layers Quiz 2025

How is the stratosphere different from the troposphere?

• The clouds in the stratosphere produce more rain.

• The air in the stratosphere has a greater density.

• The stratosphere is closer to Earth's surface than the troposphere.

• The stratosphere contains the ozone layer, while the troposphere does not.

Which of these statements best describes temperature as elevation in the atmosphere increases?

• Temperature remains constant with elevation in the thermosphere

• Temperature generally decreases with elevation in the troposphere

• Temperature generally decreases with elevation in the stratosphere

• Temperature remains constant with elevation in the mesosphere

What causes the air pressure to change in the atmosphere?

• Air pressure does not change in the atmosphere.

• More air means there is less air pressure and less air means that there is more air pressure.

• More air molecules located at the Earth's surface causes an increase as you go towards the surface.

• Less air molecules located higher in the atmosphere causes the air pressure to increase as you go higher in the atmosphere.

The circle graph shows the percentages of different gases in Earth’s atmosphere. What percentage of gas is the largest?

• oxygen; 21%

• nitrogen; 78%

• carbon dioxide; .038%

• Methane; .0001%

Why does air pressure decrease from the troposphere to the exosphere?

• There are higher temperatures as altitude increases

• The air particles are more tightly packed with less spacing at the Earth's surface and higher in the atmosphere the air particles become more spread apart and much less packed.

• There are more air molecules as altitude increases

• There are lower temperatures as altitude increases

How does the temperature of the stratosphere compare to the mesosphere?

• Stratosphere is colder than the mesosphere because the stratosphere contains the ozone layer

• Stratosphere is warmer than the mesosphere because the stratosphere contains the ozone layer

• Stratosphere is warmer than the mesosphere because the stratosphere contains the ionosphere

• Stratosphere is colder than the mesosphere because the stratosphere contains the ionosphere

Which gas makes up the largest portion of Earth's atmosphere?

• nitrogen

• oxygen

• carbon dioxide

• hydrogen

Why does air pressure decrease from the troposphere to the exosphere?

• There are higher temperatures as altitude increases

• There are more air molecules as altitude increases

• There are lower temperatures as altitude increases

• There are fewer air molecules as altitude increases
