← ScienceWhich consequence results when excessive atmospheric heating impairs satellite communications?
A)Signals experience greater ionospheric refraction✓
B)Reduced magnetic shielding affects electronics
C)Solar panel efficiency is drastically improved
D)Orbital decay due to increased atmospheric drag
💡 Explanation
Thermospheric expansion increases ionization, thereby altering the refractive index for radio waves. Signals undergo significant ionospheric refraction because of increased electron density; therefore, communications degrade, rather than improving panel efficiency or decay which are results of other mechanisms.
