Our atmosphere is made of many layers. The layer nearest to the surface of the earth is known as

Options

A. geosphere
B. stratosphere
C. troposphere
D. none of these.

Explanation

To answer the question about the layer of the atmosphere that is nearest to the surface of the Earth, follow these steps:

### Step-by-Step Solution:

1. **Understand the Atmosphere's Structure**: The atmosphere is composed of multiple layers, each defined by temperature changes and other characteristics.

2. **Identify the Layers of the Atmosphere**: The main layers of the atmosphere, starting from the surface of the Earth, are:
- Troposphere
- Stratosphere
- Mesosphere
- Thermosphere
- Exosphere

3. **Locate the Nearest Layer**: Among these layers, the one that is closest to the Earth's surface is the **Troposphere**.

4. **Confirm the Characteristics of the Troposphere**: The Troposphere is where most weather events occur and contains the majority of the atmosphere's mass. It extends from the Earth's surface up to about 8 to 15 kilometers high, depending on the location.

5. **Conclude the Answer**: Therefore, the layer nearest to the surface of the Earth is the **Troposphere**.

### Final Answer:
The layer nearest to the surface of the Earth is known as the **Troposphere**.
