A)temperature structure.
B)composition.
C)electrical charges.
D)pressure.

Question

Quizplus · Accepted Answer

The ionosphere is defined based on its electrical charges, which are created by the ionization of gas molecules in this layer. The ionosphere contains various types of ions, such as oxygen, nitrogen, and helium ions, and it plays an important role in the propagation of radio waves in the atmosphere. Temperature, composition, and pressure are also important factors in understanding the behavior of the ionosphere, but they do not define this atmospheric region in the same way as electrical charges do.
