• the sun's energy

• earth's rotation

• human activities

• earth's landforms

If the stratosphere did not contain the ozone layer, which prediciton could BEST be made about Earth's atmosphere?

• The troposphere would experience large temperature extremes each year as the seasons changed since there would be no ozone to regulate seasons.

• The troposphere would have lower temperatures since there would be no ozone layer to trap heat near Earth's surface.

• The troposphere would have higher temperatures since the lack of an ozone layer would allow Earth's surface to receive warmer air from the mesosphere.

• The troposphere would remain the same temperature since the ozone layer's function is to block out incoming ultraviolet rays and not to regulate temperature.

Which of the following is stratospheric ozone NOT responsible for?

• screening out ultraviolet radiation

• preventing ozone formation in the troposphere

• helping protect humans from sunburn and cataracts

• lowering atmospheric water vapor

How are a greenhouse and Earth's atmosphere most alike?

• Both contain large amounts of carbon dioxide.

• Both lower the temperature to be suitable for life.

• Both trap heat inside and prevent it from escaping.

• Both prevent harmful radiation from reaching Earth.

The location of the ozone is in which layer?

• in the troposphere

• in the stratosphere

• in the mesosphere

• in the thermosphere

The temperature in the troposphere, the lowest layer of Earth's atmosphere, ranges from 17 degrees Celcius to -51 degrees Celcius, decreasing as altitude increases. However, in the layer above the troposphere, the stratosphere, the temperature gradually increases to -15 degrees Celcius as the altitude increases. Why does the temperature increase with altitude in the stratosphere?

• because ozone reflects energy from the sun

• because ozone absorbs energy from the sun

• because meteoroids break apart in this layer

• because meteoroids absorb light in this layer

Where does most of Earth's weather occur?

• troposphere

• thermosphere

• mesosphere

• stratosphere

How does the troposphere protect life on Earth?

• It reflects most light away from Earth's surface so that it does not damage plants and animals.

• It holds a lot of neon gas, which is required by the circulatory system of plants and animals.

• It contains insulating water vapor that is circulated and returned to Earth's surface.

• It contains mostly ozone, which makes this layer the warmest for living organisms.

What would most likely happen if Earth did not have an atmosphere?

• Humans and animals would not survive because the oxygen level would increase, but plants would survive because the carbon dioxide level would remain the same.

• Humans and animals would survive because they would have more oxygen to breathe, and plants would survive because the carbon dioxide level would increase.

• Humans and animals would survive because the oxygen level would remain the same, but plants would not survive because the level of carbon dioxide would decrease.

• Humans and animals would not survive because they would not have oxygen to breathe, and plants would not survive without the carbon dioxide provided by humans and animals.
