The temperature of troposphere gradually decreases with altitude. Explain.

The troposphere is the layer next to the Earth's surface. On average, it extends 11 km to the top of the troposphere which is called the tropopause. In the troposphere, the temperature generally decreases with altitude. The reason is that the troposphere's gases absorb very little of the incoming solar radiation.

The troposphere gets its heat from the ground, and so temperature decreases with altitude. Warm air rises and cool air sinks and so the troposphere is unstable.

The stratosphere is the layer of the earth's atmosphere above the troposphere, extending to about 50 km above the earth's surface. In the stratosphere, however, temperature increases with altitude. The stratosphere contains the ozone layer, which protects the planet from the Sun's harmful UV.

Dear Swastika,
