Which of these is not a possible effect of an earthquake?

Options

A. Fire
B. Tsunami
C. Acid rain
D. Landslide

Answer

To determine which of the given options is not a possible effect of an earthquake, we can analyze each option one by one.

### Step-by-Step Solution:

1. **Identify the Effects of Earthquakes**:
- Earthquakes can cause various natural disasters and phenomena. We need to consider common effects associated with earthquakes.

2. **Evaluate Each Option**:
- **Option 1: Fire**: Earthquakes can lead to fires due to ruptured gas lines or electrical failures. So, this is a possible effect.
- **Option 2: Tsunami**: Underwater earthquakes can trigger tsunamis, which are large ocean waves. Therefore, this is also a possible effect.
- **Option 3: Acid Rain**: Acid rain is caused by pollutants in the atmosphere, such as sulfur dioxide and nitrogen dioxide, which are not directly related to earthquakes. Hence, this is not a possible effect of an earthquake.
- **Option 4: Landslide**: Earthquakes can destabilize land and cause landslides, making this another possible effect.

3. **Conclusion**:
- After evaluating all options, it is clear that **acid rain** (Option 3) is not a possible effect of an earthquake.

### Final Answer:
The option that is not a possible effect of an earthquake is **acid rain**.
