Detailed explanation-1: -The atmosphere can be divided into layers based on its temperature, as shown in the figure below. These layers are the troposphere, the stratosphere, the mesosphere and the thermosphere. A further region, beginning about 500 km above the Earth’s surface, is called the exosphere.

Detailed explanation-2: -The temperature gradient in each layer is determined by the heat source of the layer. The different temperature gradients in each of the four main layers create the thermal structure of the atmosphere.

Detailed explanation-3: -The layers from closest to the Earth’s surface to further away are the troposphere, stratosphere, mesosphere, thermosphere (with the ionosphere), and exosphere. The temperature increases at first then decreases, and then begins to increase again through the different layers.

Detailed explanation-4: -Earth’s atmosphere has five major and several secondary layers. From lowest to highest, the major layers are the troposphere, stratosphere, mesosphere, thermosphere and exosphere. Troposphere.
