The layer of atmosphere that is just above the earth's surface is called ______.

Options

A. thermosphere
B. troposphere
C. stratosphere
D. mesosphere

Answer

**Step-by-Step Solution:**

1. **Identify the Layers of the Atmosphere**: The atmosphere is divided into several layers, each with distinct characteristics. The main layers are the troposphere, stratosphere, mesosphere, thermosphere, and exosphere.

2. **Understand the Position of Each Layer**:
- The **troposphere** is the layer closest to the Earth's surface, where weather occurs and where we live.
- The **stratosphere** is above the troposphere and contains the ozone layer.
- The **mesosphere** is above the stratosphere.
- The **thermosphere** is above the mesosphere.
- The **exosphere** is the outermost layer.

3. **Determine Which Layer is Just Above the Earth's Surface**: Since the question asks for the layer that is just above the Earth's surface, we need to identify the layer that is immediately above the ground level.

4. **Conclude the Answer**: The layer of the atmosphere that is just above the Earth's surface is the **troposphere**.

**Final Answer**: The layer of atmosphere that is just above the earth's surface is called **troposphere**.
