Which layer of the atmosphere helps in radio transmission?


Ionosphere of the atmosphere helps in radio transmission.

Various layers in the atmosphere

Our atmosphere is composed of many components. But the structure of the atmosphere is a combination of various layers. The composition of the atmosphere is divided into five layers based on temperature. These layers are as follows:

  1. Troposphere
  2. Stratosphere
  3. Mesosphere
  4. Thermosphere
  5. Exosphere


  • The Ionosphere is the lowest part of the thermosphere.
  • Ions are electrically charged particles that make up the ionosphere.
  • This layer is defined as the layer of the atmosphere of Earth that is ionized by cosmic and solar radiation.
  • It lies between 80 and 400 kilometres above the Mesopause.
