Question

What is the reason for the increasing warming tendency with increasing altitude in the stratosphere?

Answer

The presence of ozone (O₃) in the stratosphere is the primary reason for the increasing warming tendency with increasing altitude. Ozone absorbs incoming UV radiation from the sun, releasing heat that warms the surrounding air, making the stratosphere warmer than the layers below it.
