The graph demonstrates how temperature changes with altitude in different layers of Earth’s atmosphere.

Where is the temperature the highest in the troposphere?

• • A

    Near the surface of Earth

• • B

    In the middle of the troposphere

• • C

    At the boundary of the troposphere and stratosphere

• • D

    Just below the boundary of the troposphere and stratosphere

The graph below demonstrates how temperature changes with altitude in different layers of Earth’s atmosphere.

Select the words that correctly complete the statements.

In the troposphere, the temperature (increases/decreases) as the altitude increases.

In the thermosphere, the temperature (increases/decreases) as the altitude increases.

The graph demonstrates how temperature changes with altitude in different layers of Earth’s atmosphere.

What is the highest temperature that is reached in the mesosphere?

Air pressure is caused by air particles pushing down on other surfaces due to gravity. The table below shows how atmospheric pressure changes with altitude.

Which statement explains the pattern of atmospheric pressure between sea level (0 m) and an altitude 15240 m?

 

• • A

    As altitude increases, atmospheric pressure decreases.

• • B

    As altitude increases, atmospheric pressure increases.

• • C

    As altitude increases, atmospheric pressure stays the same.

• • D

    As altitude increases, atmospheric pressure decreases and then increases.

Passage: The Ozone Layer The ozone layer is a region of Earth's atmosphere. There is a small amount of ozone gas in the atmosphere. Even so, it plays a very important role in protecting life on Earth. The ozone layer is getting thinner due to pollution. This allows more ultraviolet (UV) radiation to enter Earth's atmosphere. Excess UV radiation can have negative health effects on humans.

What can you conclude from the passage?

• A: The ozone layer is not important to life on Earth.

• B: The ozone layer is slowly moving to the mesosphere.

• C : The ozone layer helps protect the Earth from UV radiation.

• D The ozone layer causes an increase in air pressure.
