Question

The layers of the atmosphere are classified according to changes in

Answer 1

Answer:

Temperature

Explanation:

The layers of the atmosphere have been classified on the basis of the temperature of each layer that varies with the variation in altitude.

The layers of the atmosphere and the variation in temperature is given below:

1. Troposphere:

With the increase in altitude, there is a reduction in the temperature in this layer.

2. Stratosphere:

With the increase in altitude the temperature of the air also increases.

As Ozone is present in this layer, it absorbs most of the UV radiations making it warmer.

3. Mesosphere:

As a result of the decrease in the density of the air molecules, the temperature of this layer decreases with the increase in the altitude.

4. Thermosphere:

As a result of the absorption of the X-rays by the oxygen and nitrogen molecules, the temperature increases with increase in altitude.
