(b) The Thermosphere: This layer lies next to Mesosphere and in this layer the temperature drastically. It is also called the Ionosphere.

(c) The Mesosphere: It is the third layer in the earth’s atmosphere and extends up to 80 km from the surface and lies above the stratosphere.

(d) The Stratosphere: It is the second layer of the atmosphere and extends up to 50 km from the surface. It lies between troposphere and mesosphere.

(e) The Troposphere: It is the lowest layer of the atmosphere and extends up to 18 km at the equator and 8 km near the poles. It consists of all the atmospheric elements.
