Accepted Answer

### TRUE OR FALSE Section
1. **Explanation**: The lithosphere includes the crust and upper mantle (solid), not just oceans.
   Answer: false
2. **Explanation**: The lithosphere is solid (crust, mantle), while the atmosphere is gaseous.
   Answer: false
3. **Explanation**: Soil is part of the lithosphere (surface layer of Earth’s crust).
   Answer: true
4. **Explanation**: Oxygen is a major gas in the atmosphere.
   Answer: true
5. **Explanation**: Living things (like plants) use CO₂ and produce O₂; animals use O₂ and produce CO₂, but all need both in cycles.
   Answer: true (Note: Simplified for context—living things rely on these gases for respiration/photosynthesis.)
6. **Explanation**: The air (atmosphere) is not part of the hydrosphere (water bodies).
   Answer: false
7. **Explanation**: Earth’s conditions (atmosphere, water, temperature) support life.
   Answer: true
8. **Explanation**: The hydrosphere is water (liquid, gas, solid), not a gas mixture (that’s the atmosphere).
   Answer: false
9. **Explanation**: Most rivers/lakes are freshwater (low salt), while oceans are saltwater.
   Answer: false
10. **Explanation**: The ground (crust) is part of the lithosphere.
    Answer: true

### REACHING OUT Section (Prefix Meanings + Words)
#### “litho-”
- **Meaning**: Relating to stone/rock (from Greek “lithos” = stone).
- **Example Words**:
  - *Lithosphere*: The rigid outer layer of Earth (stone/rock layer).
  - *Lithology*: The study of rock types.

#### “hydro-”
- **Meaning**: Relating to water (from Greek “hydor” = water).
- **Example Words**:
  - *Hydrosphere*: All water on Earth (oceans, rivers, etc.).
  - *Hydrology*: The study of water movement and distribution.

(For additional words, use a dictionary: e.g., *Lithograph* (printing with stone), *Hydroelectric* (power from water).)
