Why can the D layer show a stronger effect during daytime?
Answer and explanation
Correct answer: Ionization increases due to solar radiation during daytime
The governing concept is solar photoionization in the ionosphere. During daylight, solar ultraviolet and X-ray radiation removes electrons from atmospheric molecules and produces more charged particles in the D region. The enhanced electron density can increase absorption of certain radio frequencies, especially lower-frequency signals. Rainfall, disappearance of the tropopause, and liquefaction of all gases are unrelated, so option A is correct.
