Ozone layer is present in ………layer of atmosphere:

Options

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

Answer

To determine the layer of the atmosphere where the ozone layer is present, we can follow these steps:

1. **Identify the Ozone Layer**: The ozone layer is a region in the atmosphere that contains a high concentration of ozone (O3) molecules.

2. **Understand the Layers of the Atmosphere**: The atmosphere is divided into several layers, including the troposphere, stratosphere, mesosphere, thermosphere, and exosphere. Each layer has distinct characteristics and functions.

3. **Locate the Stratosphere**: The stratosphere is the layer of the atmosphere that lies above the troposphere and below the mesosphere. It is known for its stable conditions and is where the ozone layer is located.

4. **Recognize the Function of the Ozone Layer**: The primary function of the ozone layer is to absorb the majority of the Sun's harmful ultraviolet (UV) radiation, protecting living organisms on Earth from its damaging effects.

5. **Conclude the Answer**: Since the ozone layer is concentrated in the stratosphere, we can conclude that the ozone layer is present in the stratosphere.

Final Answer: The ozone layer is present in the **stratosphere**.
