Question

what physical change occurs in the stratosphere due to the absorption of ultraviolet radiation? cooling effect increased heating decreased air pressure

Explanation:

In the stratosphere, ozone absorbs ultraviolet radiation. This absorption process converts the UV energy into heat. As a result, the stratosphere experiences increased heating. The cooling effect is incorrect as absorption of UV (which has energy) would not lead to cooling. Decreased air pressure is not a direct physical change due to UV absorption; air pressure in the stratosphere is mainly related to altitude - related factors like the number of air molecules per unit volume at that height, not directly to UV absorption.

Answer:

Increased heating
