Earth's Atmospheric Layers Quiz ESS7.1

How are the boundaries of the Earth’s atmospheric layers determined?

• by water content

• by gases present

• by relative humidity

• by temperature differences

In which layer is the atmosphere most dense?

• exosphere

• troposphere

• mesosphere

• thermosphere

Which statement best describes the relationship between air pressure and elevation as one gets closer to the troposphere?

• Air pressure increases as elevation increases.

• Air pressure increases as elevation decreases.

• Air pressure decreases as elevation decreases.

• There is no clear relationship between air pressure and elevation.

How is the stratosphere different from the mesosphere?

• The stratosphere is less dense.

• The stratosphere burns more meteors.

• The stratosphere has lower temperatures.

• The stratosphere protects people from ultraviolet rays.

How does the sun contribute to weather patterns?

• The sun condenses water into snow or rain, which falls to the surface again.

• The sun provides energy to evaporate water into the atmosphere.

• The sun cools air as it flows across the surface of the earth.

• The sun forms the clouds and moves them across the sky.

Michelle’s air conditioner stopped working, so she decided to cool off downstairs until nightfall. Which characteristic of air pressure explains Michelle’s choice?

• Warm air is less dense and tends to rise; cool air is more dense and tends to sink.

• Warm air is less dense and tends to sink; cool air is more dense and tends to rise.

• Warm air is more dense and tends to rise; cool air is less dense and tends to sink.

• Warm air is more dense and tends to sink; cool air is less dense and tends to rise.

How does the ozone layer affect Earth?

• It forms a magnetic field in the mesosphere of Earth.

• It increases the amount of nitrogen in the troposphere of Earth.

• It prevents the formation of severe storms in the stratosphere of Earth.

• It helps reduce the amount of ultraviolet radiation reaching the surface of Earth.

A weather report predicts warm temperatures and thunderstorms for the afternoon. How will the air pressure most likely change?

• It will increase.

• It will decrease.

• It will remain constant.

• It will decrease and then increase rapidly.

Which atmospheric layer has the highest temperature?

• mesosphere

• stratosphere

• thermosphere

• troposphere

What happens to the amount of water on Earth as it goes through the water cycle?

• The amount of water on Earth decreases because of evaporation during the water cycle.

• The amount of water on Earth increases because of precipitation during the water cycle.

• The amount of water on Earth stays the same because water changes form as it moves through the water cycle.

• The amount of water on Earth cannot be determined because it is constantly moving through the water cycle.
