A)It primarily absorbs harmful infrared wavelengths.
B)All radio signals pass through this region virtually unaffected.
C)Radio waves from GPS are strengthened in the ionosphere.

E)The region principally absorbs gamma rays,X-rays,and interacts with the solar wind.

Question

Quizplus · Accepted Answer

The ionosphere is a layer of Earth's atmosphere that is ionized by solar and cosmic radiation. It absorbs gamma rays, X-rays, and interacts with the solar wind, making it crucial for radio communication by reflecting radio waves back to Earth. It does not primarily absorb infrared wavelengths, nor are all radio signals unaffected by it. GPS signals can be affected by the ionosphere, but they are not strengthened. The depletion of the ozone layer, not the ionosphere, is associated with chlorofluorocarbons.
