Structure of the Atmosphere

Temperature increases as altitude increases in both the stratosphere and the thermosphere. What is the main difference between these two layers?

• The temperature increases in the stratosphere because of aurora borealis, and in the thermosphere because of the jet stream.

• The temperature increases in the stratosphere because ozone absorbs ultraviolet radiation, and in the thermosphere because of direct exposure to the sun.

• The temperature increases in the stratosphere because of direct exposure to the sun, and in the thermosphere because ozone absorbs ultraviolet radiation.

• The temperature increases in the stratosphere because of the jet stream, and in the thermosphere because of aurora borealis.

Which statement best describes the ozone layer of Earth?

• It helps reduce the amount of ultraviolet radiation reaching the surface of earth

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

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

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

The layers of gasses, vapour, and dust particles that surround earth is called _______.

• Atmosphere

• Lithosphere

• Hydrosphere

• Biosphere
