Absence of which upper region could most affect long distance radio communication?
Answer and explanation
Correct answer: Ionosphere
The ionosphere contains electrically charged particles produced by solar radiation. These electrons and ions can refract, reflect, or otherwise modify certain radio waves, allowing some signals to travel far beyond the horizon. If this region were absent, long-distance communication using suitable high-frequency bands could be greatly reduced or altered. The troposphere affects local propagation, while the stratopause is only a boundary and the surface layer is too low.
