Ozonosphere is component of

Options

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

Answer

To determine what the ozonosphere is a component of, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Definition of Ozonosphere**:
The ozonosphere, also known as the ozone layer, is a region of Earth's stratosphere that contains a high concentration of ozone (O3) molecules.

2. **Identify the Layers of the Atmosphere**:
The atmosphere is divided into several layers, including:
- Troposphere
- Stratosphere
- Mesosphere
- Thermosphere

3. **Locate the Ozone Layer**:
The ozone layer is primarily found in the stratosphere. This layer is situated above the troposphere and below the mesosphere.

4. **Understand the Role of the Ozone Layer**:
The ozone layer plays a crucial role in absorbing the majority of the sun's harmful ultraviolet (UV) radiation, which protects living organisms on Earth.

5. **Conclude the Relationship**:
Since the ozonosphere is located within the stratosphere and is defined by the presence of ozone, we can conclude that the ozonosphere is a component of the stratosphere.

### Final Answer:
The ozonosphere is a component of the **stratosphere**.
