What is an example of a periodic event?

• A. Earthquakes
• B. Volcanic eruptions
• C. The daily movement of tides
• D. Deforestation

Answer: (C)

Periodic events are those that repeat at regular time intervals. The daily movement of tides fits this idea because tides come in a predictable cycle—roughly every 12 hours with high and low tides repeating as the Moon and Sun pull on Earth's oceans while the planet rotates. This regular rhythm makes tides a classic example of a periodic phenomenon. In contrast, earthquakes and volcanic eruptions occur irregularly and without a fixed schedule, and deforestation is a long-term human activity rather than a repeating cycle.
