What kinds of decisions are involved in self-definition? give an example of decisions you must make for yourself

Self-definition is one of the most important processes that humans can take part in. When we "self-define" ourselves, we are striving to understand our individual worth in distinction from our interpersonal or social role.

In order to do so, we need to take part in decisions that make us unique. Some of these decisions include choosing our career, learning a new hobby or analyzing our moral values.

capture hypothesis - the moon was locked into orbit by earths gravity as it was passing by it.

accretion hypothesis - the moon was formed from collisions and combining of planetesimals.
