How does change in temperature occur depending on the altitude in troposphere and stratosphere?

The temperature decreases with the rise in altitude in the troposphere.

The temperature increases with the rise in altitude in the stratosphere.

Explanation:

Troposphere is the layer of atmosphere, closest to the ground. It has maximum number of gases. Troposphere gets heated up due to the radiations reflecting back from earth. That means the layer of troposphere nearer to the earths surface is warmer than the higher layers. Thus the temperature decreases with rise in altitude in the troposphere. Troposphere is followed by a troposphere. This is a transition zone between troposphere and stratosphere. Here no changes takes place with rise in altitude. Second layer of atmosphere, that lies next to troposphere is stratosphere. Stratosphere has similar composition as that of the troposphere except for the presence of the layer of ozone in it. The stratosphere gets heated up due to the trapping of heat by the ozone layer. Ozone gets heated up due to the ultraviolet radiations of the sun. That means the higher layers of the stratosphere is more heated up than the lower layers. Thus, With increase in altitude the temperature also increases in the stratosphere.
