The basic reason is that AM radio is broadcast on a lower frequency, while FM is broadcast on a higher frequency. And the lower frequency signals will curve around the earth a bit more than the higher frequency FM signals. FM is considered more "line of sight" than AM, which has that "fat" ground wave that hugs the earth a bit more.

AM radio waves are able to traves farther than FM radio waves because?
AM radio waves have longer wavelengths compared to FM radio waves, allowing them to diffract or bend around obstacles such as buildings and hills. This enables AM radio waves to travel greater distances and provide better coverage in areas with obstructions. FM radio waves, on the other hand, travel in straight lines and are more affected by obstacles.
