Ionosphere
The ionosphere reflects radio waves back to Earth. Actually I heard it is refraction, not reflection; but the term "reflection" is commonly used.
The layer of charged particles in Earth's atmosphere is called the ionosphere. The most famous application of this layer is AM radio, which bounces its waves off of the ionosphere for radio receivers to use.
The ionosphere there are particles called ions in the ionosphere (hens the name). The ions cause radio waves from am radio stations to bounce off of it.
The methosphere is a layer but it is not a major layer of the earth
the outer layer of the earth
To be specific, its ionosphere. It is one of the layers above the earth's atmosphere consisting of ions of gases. Radio signals are reflected back to the earth from this very layer.

The layer of charged particles in Earth's atmosphere is called the ionosphere. The most famous application of this layer is AM radio, which bounces its waves off of the ionosphere for radio receivers to use.
The ionosphere bends radio waves . . . most go out into space, but a fair number hit the earth far away, and are reflected back up to the ionosphere. Radio operators call this phenomenon, "The skip".
I believe it is the Ionosphere.
Radio waves are reflected by many solid objects, such as wood, stone, and notably metal, allowing the use of microwaves in radar applications.Also importantly in broadcast radio, the ionosphere (an upper layer of the Earth's atmosphere) can bounce signals back down to locations beyond the line-of-sight horizon.
The troposphere... It acts like a gigantic mirror - reflecting radio waves back to Earth.
The atmospheric layer that refracts (bends) radio signals is called the ionosphere. The radio waves are reflected a little, as you say, but are mostly refracted, that is, bent, back to earth. Happenss in the daytime, too, but too little to be useful in most cases. By the way, it is a similar process that messes up GPS locator precision.
The ionosphere contains weakly ionized gas which reflects radio waves.
