Why do am radio waves travel farther than fm?

How are AM and FM radio waves different? The difference is in how the carrier wave is modulated, or altered.

With FM, the frequency (the number of times each second that the current changes direction) of the carrier signal is varied.

Why does AM radio go further night? Most AM radio stations are required by the FCC’s rules to reduce their power or cease operating at night in order to avoid interference to other AM stations. … However, during nighttime hours the AM signals can travel over hundreds of miles by reflection from the ionosphere, a phenomenon called “skywave” propagation.
