Temperature increases with height in which of the spheres?

Options

A. Troposphere
B. Stratosphere
C. Mesosphere
D. None of these

Answer

To solve the question "Temperature increases with height in which of the spheres?", we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Layers of the Atmosphere**:
The Earth's atmosphere is divided into several layers: the troposphere, stratosphere, mesosphere, and thermosphere. Each layer has distinct temperature characteristics.

2. **Analyze Temperature Trends**:
- **Troposphere**: In this layer, temperature generally decreases with height. It is the lowest layer of the atmosphere where weather occurs.
- **Stratosphere**: In this layer, temperature increases with height. This is due to the presence of the ozone layer, which absorbs and scatters ultraviolet solar radiation, leading to warming.
- **Mesosphere**: In this layer, temperature again decreases with height.
- **Thermosphere**: In this layer, temperature increases significantly with height, but it is not the focus of the question.

3. **Identify the Correct Layer**:
Based on the analysis, the layer where temperature increases with height is the stratosphere.

4. **Conclusion**:
Therefore, the correct answer to the question is the stratosphere.

### Final Answer:
The temperature increases with height in the **stratosphere**.
