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
