In which layer of the atmosphere is ozone found ?
Show Hint
- Troposphere
- Stratosphere
- Mesosphere
- Thermosphere
The Correct Option is B
Solution and Explanation
Ozone is a form of oxygen made of three oxygen atoms (O3). The question asks about the layer of the atmosphere that holds it.
Step 2: Recall the facts:
The ozone layer is found in the stratosphere, about 15 to 35 km above the earth.
It absorbs harmful ultraviolet rays of the sun. Its thinning, called the ozone hole, is a major global environment issue.
Step 3: Check the options:
(A) Troposphere is the lowest layer, where weather occurs. Wrong.
(B) Stratosphere holds the ozone layer. Correct.
(C) Mesosphere is above the stratosphere. Wrong. (D) Thermosphere is higher still. Wrong.
Final Answer:
Ozone is found in the stratosphere. The correct option is (B).
