The burning of fossil fuels such as coal and petroleum leads to an increase in the concentration of sulfur dioxide in atmosphere. This sulfur dioxide changes into sulfuric acid in the atmosphere, causing acid rains. Which of the following effects is not a consequence of acid rains?

Options

A. Damage to buildings and monuments
B. Increase in the temperature of Earth
C. Reduction in the growth of trees
D. Reduction of marine population

Answer

To solve the question regarding the consequences of acid rain, follow these steps:

### Step-by-Step Solution:

1. **Understand the Source of Acid Rain**:
- Acid rain is primarily caused by the burning of fossil fuels like coal and petroleum. This process releases sulfur dioxide (SO2) into the atmosphere.

2. **Formation of Sulfuric Acid**:
- The sulfur dioxide in the atmosphere reacts with water vapor and oxygen to form sulfuric acid (H2SO4), which then falls to the ground as acid rain.

3. **Identify the Consequences of Acid Rain**:
- Acid rain has several harmful effects:
- **Damage to buildings and monuments**: Acid rain can corrode and damage structures, especially those made of limestone and marble.
- **Reduction in the growth of trees**: Acid rain can harm forests by leaching essential nutrients from the soil and directly damaging leaves.
- **Reduction in marine population**: Acid rain can lower the pH of water bodies, affecting aquatic life and reducing fish populations.

4. **Evaluate the Given Options**:
- The question asks which of the following is NOT a consequence of acid rain:
- A) Damage to buildings and monuments
- B) Increase in the temperature of earth
- C) Reduction in the growth of trees
- D) Reduction in marine population

5. **Identify the Incorrect Option**:
- Among the options, the increase in the temperature of the earth (Option B) is not a direct consequence of acid rain. Acid rain primarily affects structures, vegetation, and aquatic ecosystems, but it does not contribute to global warming or temperature increase.

6. **Conclusion**:
- Therefore, the correct answer is **Option B: Increase in the temperature of earth**.
