Which of the following atmospheric layers contains the ozone layer that absorbs harmful ultraviolet radiation from the Sun?

A. Troposphere
B. Stratosphere✓ Correct Answer
C. Mesosphere
D. Thermosphere

💡 Solution & Explanation

The stratosphere extends from about 12 to 50 kilometers above the Earth and contains high concentrations of ozone molecules that absorb harmful ultraviolet radiation from the Sun. Layers closer to the surface, such as the troposphere, host weather phenomena, whereas higher zones like the mesosphere and thermosphere experience different temperature gradients and ionization processes. Ozone depletion is primarily driven by synthetic chlorofluorocarbons released into the atmosphere.
