Which atmospheric layer 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 Earth's surface and contains the ozone layer, which filters out harmful ultraviolet radiation. Unlike the troposphere below it, temperatures in the stratosphere rise with altitude due to this UV absorption. Troposphere accounts for weather phenomena, while thermosphere and mesosphere lack sufficient ozone concentrations to block solar radiation effectively.
