The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding the Statement**: The statement claims that the occurrence of an earthquake is a periodic change. We need to analyze what periodic changes are. 2. **Definition of Periodic Change**: Periodic changes are those that occur at regular intervals of time. Examples include the rotation of the Earth, seasons, and tides, which happen in a predictable manner. 3. **Nature of Earthquakes**: Earthquakes are natural disasters that occur due to the sudden release of energy in the Earth's crust. They do not follow a predictable pattern or schedule. 4. **Lack of Predictability**: Unlike periodic changes, earthquakes can happen at any time and place without any warning. There is no fixed interval or regularity to their occurrence. 5. **Conclusion**: Since earthquakes do not occur at regular intervals and are unpredictable, the statement that the occurrence of an earthquake is a periodic change is false. 6. **Final Answer**: Therefore, the statement is false because earthquakes are non-periodic changes. ---
