In which among the following layers of the atmosphere, Ozone layer is present to protect us against harmful UV-Ultra Violet rays ?

Correct option is B

The correct answer is (B) Stratosphere

1. The ozone layer is concentrated in the lower portion of the stratosphere, about 15 to 35 kilometers above Earth's surface.

2. The ozone molecules absorb the majority of the Sun's UV-B and UV-C rays, which can be harmful to human health.

3. This protective function helps prevent skin cancer, cataracts, and other health issues caused by excessive UV exposure.

4. The ozone layer also plays a role in maintaining the balance of Earth's ecosystems.

5. Efforts to protect the ozone layer have led to global agreements like the Montreal Protocol, which has successfully reduced the use of ozone-depleting chemicals.

6. The ozone layer is slowly recovering due to these environmental protections.

• Mesosphere – The mesosphere lies above the stratosphere but does not contain the ozone layer.

•  Troposphere – The troposphere is the lowest layer of the atmosphere, where weather occurs, but it does not contain the ozone layer.

•  Thermosphere – The thermosphere is above the mesosphere and is known for its high temperatures but does not contain the ozone layer.
