The formation of day and night is a periodic change.

• A. True
• B. False

Answer 1

The correct option is A True

Periodic change

• Periodic changes are the changes that repeat themselves after a regular interval of time.
• Germination of a seed is not a periodic change because once it is germinated, it cannot be reversed back to a seed.
• For example, the Pendulum of a clock, day and night formation, etc is a periodic change.

Day and night formation

• The earth spins around its own axis and revolves around the sun.
• Day and night are caused by the earth's rotation.
• The day is experienced by the part of the earth that faces the sun, whereas the night is experienced by the part of the earth that is not facing the sun.
• Based on this, day and night occur periodically at a place.

Hence, the formation of day and night is a periodic change.
