Which would be considered the most direct result of ozone-layer depletion?
Answer and explanation
Correct answer: An increase in ultraviolet radiation reaching the surface
Stratospheric ozone absorbs much of the Sun’s harmful ultraviolet-B radiation before it reaches Earth’s surface. If the ozone layer is depleted, its filtering capacity decreases, so more ultraviolet radiation reaches the ground, increasing risks to human health, crops, and ecosystems. Option A states this direct consequence. The other options incorrectly describe changes to nitrogen, argon, or water vapour.
