Explanation:

Cause and effect. Through experience, it is known that no phenomenon arises without cause, "in itself", but is generated by the preceding development of said phenomenon or other phenomena. Nothing comes from nothing. Every phenomenon has its origin, which it begets it, it is precisely what is called “cause.” What creates, produces or gives life to another phenomenon and precedes it in time is called the cause.What arises under the action of the cause is called the effect.
