Atmosphere consists of:

Options

A. Lithosphere + Hydrosphere
B. Lithosphere + Stratosphere + Hydro sphere
C. Troposphere + Stratosphere + Ionosphere
D. None of the above.

Answer

**Step-by-Step Solution:**

1. **Understanding the Atmosphere**: The atmosphere is a layer of gases surrounding the Earth. It is composed of various layers, each with distinct characteristics.

2. **Identifying the Options**: The question provides several options:
- Lithosphere
- Hydrosphere
- Troposphere, Stratosphere, and Ionosphere
- None of the above

3. **Excluding Irrelevant Options**:
- **Lithosphere**: Refers to the Earth's crust and upper mantle, which is solid and not part of the atmosphere. Therefore, it can be excluded.
- **Hydrosphere**: Refers to all the water bodies on Earth (oceans, rivers, etc.), which are also not part of the atmosphere. This option can also be excluded.

4. **Analyzing the Remaining Option**: The third option includes:
- **Troposphere**: The lowest layer of the atmosphere where weather occurs and where we live.
- **Stratosphere**: The layer above the troposphere that contains the ozone layer, which protects us from harmful UV radiation.
- **Ionosphere**: A region of the atmosphere that is ionized by solar and cosmic radiation, located between the mesosphere and thermosphere.

5. **Conclusion**: The correct answer is the third option, which includes the Troposphere, Stratosphere, and Ionosphere. These are indeed layers of the atmosphere.

**Final Answer**: The atmosphere consists of the Troposphere, Stratosphere, and Ionosphere.
