  1. In which of the following layer of atmosphere the absorption and scattering of the solar ultraviolet radiation takes place?
    1. Troposphere
    2. Stratosphere
    3. Mesosphere
    4. Thermosphere
Correct Option: B

Solar ultraviolet radiation undergoes absorption and scattering as it passes through the stratospheric layer of the earth’s atmosphere. The ozone layer, a region of Earth’s stratosphere, absorbs 97-99% of the Sun’s ultraviolet (UV) radiation. As a result, no UV radiation at wavelengths shorter than 290 nm reaches the surface of the earth.
