In the fourth layer of Earth’s surface, the thermosphere, the air is thin, meaning that there are far fewer air molecules. The thermosphere is very sensitive to solar activity and can heat up to 1,500°C or higher when the Sun is active making an aurora that lights up the night sky. Astronauts orbiting Earth in the space station or space shuttle spend their time in this layer. This layer reflects radio waves.

The ionosphere lies mostly in the thermosphere and extends from a height of ~ 65 Km to about 400 km above the earth’s surface
