FM tends to work on line of sight, (somewhat) Earth and large buildings can cause the signal to be lose or weaken.
AM can bounce all over the place but is very much affected by stray electrical interfence and metal blockage. Does not like to go into buildings as well as FM.

How close you are to the transmitter, the length and height of your antenna, how good the initial tuning stage of the radio is, how well it rejects image frequencies, the selectivity and the sensitivity of the radio. The lack of structure, or the presence of structures, or natural formations of hills, mountains or trees between the radio and the transmitter. Atmospheric conditions play a very important role in radio reception, and whether or not reflected radio waves are reaching your radio at, or near the same time as the primary signal is reaching it. This subject can be very esoteric since there is a vast multitude of things that can effect radio reception.

Because your radio would need to be near a brand new State of the Art Radio Tower that was built on flat land (in the plains states perhaps) for the very best reception!! @80)

Because your closeness to a radio tower determines the strength of the signal.

It is because of the frequency wave that bounce from the horizon to the ground.
