Final answer:
The temperature of the stratosphere decreases as altitude increases due to the decreasing concentration of heat-absorbing gases, except in the specific region of the stratopause where it starts to increase again.
Step-by-step explanation:
The temperature of the stratosphere decreases as altitude increases.
This is due to the fact that the stratosphere is above the troposphere, which is the layer of the atmosphere closest to the Earth's surface. In the troposphere, temperature decreases with increasing altitude due to the decreasing concentration of heat-absorbing gases. However, in the stratosphere, the temperature actually starts to increase with altitude because of the presence of the ozone layer, which absorbs the Sun's ultraviolet radiation and warms the surrounding air.
Overall, the temperature in the stratosphere decreases with altitude, but there is a specific region called the stratopause where the temperature starts to increase again before reaching another layer called the mesosphere.
