AM=amplitude modulation. Which is done by varying the volume of the carrier wave.
FM=frequency modulation. Which is done by varying the frequency of the carrier wave. This uses a very high frequency which gives greater clarity.

AM = Low sound quality, prone to interference especially after dark. Can cover up to 100 miles depending on transmitter power and antenna during the day, and up to several thousand after dark on a clear channel. Uses internal antenna in the listener's radio.
FM = High sound quality, much less prone to interference and fading, Constant coverage of up to 100 miles depending on transmitter power and antenna height, unaffected by day or night.
Uses telescopic external antenna on listeners's radio

A different frequency band. See details to these two bands on Wikipedia...
