Periodic changes are changes that occur periodically at regular intervals.

Periodic Change

Periodic change is a type of change that occurs repeatedly after a fixed interval of time. These changes can be observed in various natural phenomena, such as the rotation of the earth around the sun, the changing of the seasons, the tides, and the phases of the moon.

Examples of Periodic Change

1. Seasons

The changing of seasons is a classic example of periodic change. The change occurs every year at a fixed interval of time. The seasons are caused by the tilt of the earth's axis, and as the earth orbits around the sun, different parts of the planet receive varying amounts of sunlight, leading to the four seasons - spring, summer, autumn, and winter.

2. Tides

Tides are another example of periodic change that occurs due to the gravitational forces of the moon and the sun on the earth's oceans. The high and low tides occur every day at fixed intervals of time, caused by the rotation of the earth and the changing positions of the moon and the sun.

3. Phases of the Moon

The phases of the moon are another example of periodic change. The moon rotates around the earth, and as it does so, different parts of the moon are illuminated by the sun, leading to the different phases - full moon, new moon, waxing crescent, waning gibbous, and more.

Conclusion

In conclusion, periodic change is a type of change that occurs repeatedly after a fixed interval of time. These changes can be observed in various natural phenomena, such as the seasons, tides, and phases of the moon. Understanding these changes is important as they help us predict and prepare for future events.
