Question

Which atmospheric layer contains the maximum concentration of Ozone?

• A. Troposphere
• B. Stratosphere
• C. Mesosphere
• D. Thermosphere

Hint:

\textbf{Ozone layer = Stratosphere (10–50 km)}.
Protects Earth from harmful UV radiation.

Answer 1

The Correct Option is B

Concept: The Earth's atmosphere is divided into different layers based on temperature and composition. Ozone (\(O_3\)) plays a crucial role in absorbing harmful ultraviolet (UV) radiation.
Step 1: Understanding ozone distribution.
Ozone is present in small amounts throughout the atmosphere but is highly concentrated in a specific layer forming the ozone layer.
Step 2: Identifying the correct layer.
The Stratosphere, located approximately 10–50 km above Earth's surface, contains the maximum concentration of ozone.
Step 3: Eliminating incorrect options.

• Troposphere contains weather phenomena but little ozone.
• Mesosphere has very low ozone concentration.
• Thermosphere is characterized by ionized gases, not ozone concentration.

Conclusion:
Thus, the correct answer is Stratosphere.
