Solution
The layer present right above the mesosphere extending to a height of 450 km is the thermosphere. This layer is composed of electrically charged ions that are responsible for reflecting the radio waves back to the Earth's surface. Due to the presence of these ions, thermosphere is also known as ionosphere.
