Attackers need a certain amount of information before launching their attack. one common place to find information is to go through the trash of the target to find information that could be useful to the attacker. this process of going through a target’s trash is known in the community as

Dumpster diving.

Explanation:

Did an assignment on this.

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.

i think this is right, if not and you know better let me know.
