This is your last question of 1001 questions:

Since the information (modulation/voice) is repeated in both sides of
the modulation envelope in am, ssb "chops off" one half of the envelope.
The receiver is responsible for "mirroring" the other and reproducing
the information on that end--this allows for almost doubling the
effective range of am.
