Explanation:

The stereotype is the way (the series of thoughts and predictions) in which a person or a group of people is perceived as a result of their characteristics, that is, it is that immutable idea or notion that one social group has over another, which behaviors, qualities, abilities or distinctive features are generally attributed to it.

giant impact theory - the moon was formed from the collision between earth and another mars-sized body.

colliding planetesimals hypothesis - the moon was formed from the same cloud of material as earth.

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.
