Define the following with suitable examples.

(ii) Periodic and Non periodic change
(iii) Temporary and Permanent change
Define the following with suitable examples.
(i) Natural and Manmade change
(ii) Periodic and Non periodic change
(iii) Temporary and Permanent change
(i) Natural Change: A change that occurs naturally on its own is called a natural change.
Eg. changing of the season, the occurrence of tides, eclipses.
Man-made Change: A man-made change is one that occurs because of human activities.
E.g. Changing the direction of the flow of a river by building a dam.
(ii) Periodic Change: A change that is repeated after regular intervals of time is called a periodic change.
Examples: Swinging of a pendulum, rising and setting of the sun at a given place.
Non-periodic Change: A change that does not occur after regular intervals of time is called a non-periodic change. Examples: Occurrence of flood and cyclones.
(iii) Temporary Change: Temporary changes are the changes that are there only for a short period of time. Generally, temporary changes are reversible.
Example: Lighting an electric bulb, heating an iron rod, etc.
Permanent Change: Permanent changes are the changes that remain for a longer time and are not reversible.
Example: Burning of Paper. Digestion of food, etc.
