The correct Answer is:
To solve the question regarding the lowest layer of the atmosphere that extends up to 10 km from sea level, we can follow these steps: ### Step-by-Step Solution: 1. **Understanding the Atmosphere**: The atmosphere is the gaseous envelope surrounding the Earth. It consists of several layers, each with distinct characteristics. 2. **Identifying the Layers of the Atmosphere**: The atmosphere is divided into several layers: - **Troposphere**: Extends from the Earth's surface up to about 10 km. - **Stratosphere**: Extends from the top of the troposphere up to about 50 km. - **Mesosphere**: Extends from the top of the stratosphere up to about 80 km. - **Thermosphere**: Extends from the top of the mesosphere up to about 500 km. - **Exosphere**: Extends from the top of the thermosphere up to about 700 km. 3. **Determining the Lowest Layer**: Since the question specifies the lowest layer that extends up to 10 km from sea level, we identify that this layer is the **Troposphere**. 4. **Conclusion**: Therefore, the answer to the question is that the lowest layer of the atmosphere, which extends up to 10 km from sea level, is the **Troposphere**. ### Final Answer: The lowest layer of the atmosphere that extends up to 10 km from sea level is the **Troposphere**. ---
