In which context is ozone in the stratosphere most important?
Answer and explanation
Correct answer: Protection from solar ultraviolet radiation
Stratospheric ozone absorbs a substantial part of the Sun’s harmful ultraviolet radiation, especially UV-B and UV-C. By reducing the radiation reaching Earth’s surface, it helps protect living organisms from cellular and genetic damage. Ozone also affects stratospheric heating, but radiation shielding is the key context asked here. Therefore option D is correct; river erosion, soil formation and tides are not its principal atmospheric role.
