Answer is Right!
Answer is Wrong!

The ionosphere is a region of Earth’s atmosphere that is ionized by solar radiation. It is located in the upper atmosphere, from about 50 to 1000 kilometers above the Earth’s surface. The ionosphere is important for radio communications, as it reflects radio waves back to Earth.
The mesosphere is the third major layer of Earth’s atmosphere, just
