Answer:
The thermosphere is the layer in the Earth's atmosphere directly above the mesosphere and below the exosphere. Within this layer of the atmosphere, ultraviolet radiation causes photoionization/photodissociation of molecules, creating ions; the thermosphere thus constitutes the larger part of the ionosphere.

Answer:
Answer: 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.
