Question

Which layer of the atmosphere contains Ozone Layer ?

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

Hint:

Remember that while "bad" ozone (smog) can form in the troposphere near the ground, "good" ozone, which forms the vital solar UV filter, is concentrated in the Stratosphere.

Answer 1

The Correct Option is C

Step 1: Recall the layers of the atmosphere.
From bottom to top, the layers are: Troposphere, Stratosphere, Mesosphere, Thermosphere, and Exosphere.
Step 2: Locate the Ozone Layer.
The Ozone Layer sits in the Stratosphere, approximately 15 to 35 km above Earth's surface. It absorbs harmful ultraviolet radiation from the Sun, protecting life on Earth.
Step 3: Confirm the answer.
The Troposphere contains weather, the Mesosphere is where meteors burn up, and the Exosphere is the outermost layer. Only the Stratosphere houses the Ozone Layer.
\[ \boxed{\text{Stratosphere}} \]
