Which of the following is true of the ionosphere?
A) It primarily absorbs harmful infrared wavelengths.
B) All radio signals pass through this region virtually unaffected.
C) The region principally absorbs gamma rays, X-rays, and interacts with the solar wind.
D) It is being depleted through interactions with human-produced chlorofluorocarbons.

Question

Quizplus · Accepted Answer

The ionosphere primarily interacts with high-energy radiation such as gamma rays and X-rays, as well as the solar wind. It does not primarily absorb harmful infrared wavelengths (choice A) or all radio signals (choice B). There is no evidence that the ionosphere is being depleted through interactions with human-produced chlorofluorocarbons (choice D).
