Classification of Change: Periodic and Non-periodic Changes:
- Periodic Changes: Changes that occur repeatedly at regular intervals of time are called periodic changes. For example, day and night, phases of the moon, seasons, heartbeat, etc.
- Non-periodic Changes: Changes that do not follow a regular pattern or fixed time intervals are called non-periodic changes. For example, rainfall, lightning, earthquakes, etc.
