Step-by-step explanation:
An abortion is the intentional ending of a pregnancy, while a spontaneous termination is a miscarriage that occurs naturally. Abortion laws vary between states and usually consider fetal viability as the criteria for allowing or preventing the procedure. Some countries still prohibit abortion, while others place limits on when it is allowed, such as when the life of the person carrying the pregnancy is at risk.
