What is the correct sequence of atmosphere layers starting from earth?

Options

A. Stratosphere, troposphere, mesosphere, thermosphere
B. Troposphere, stratosphere, mesosphere, thermosphere
C. Mesosphere, troposphere, stratosphere, thermosphere
D. Thermosphere, mesosphere, stratosphere, troposphere

Answer

To determine the correct sequence of the atmosphere layers starting from the Earth, we need to identify and list the layers in order from the surface of the Earth upwards.

### Step-by-Step Solution:

1. **Identify the Layers of the Atmosphere**: The atmosphere is divided into five main layers:
- Troposphere
- Stratosphere
- Mesosphere
- Thermosphere
- Exosphere

2. **Order the Layers from Earth Outwards**:
- The layer closest to the Earth's surface is the **Troposphere**. This layer extends from the surface up to about 12 kilometers.
- Above the Troposphere is the **Stratosphere**, which extends from approximately 12 kilometers to 50 kilometers.
- Next is the **Mesosphere**, which ranges from about 50 kilometers to 80 kilometers.
- The **Thermosphere** follows, extending from 80 kilometers to about 700 kilometers.
- Finally, the outermost layer is the **Exosphere**, which stretches from about 700 kilometers to 10,000 kilometers.

3. **Write the Correct Sequence**: Based on the order from the Earth's surface upwards, the correct sequence of the atmosphere layers is:
- Troposphere
- Stratosphere
- Mesosphere
- Thermosphere
- Exosphere

### Final Answer:
The correct sequence of atmosphere layers starting from Earth is:
1. Troposphere
2. Stratosphere
3. Mesosphere
4. Thermosphere
5. Exosphere
