If the ozone layer were absent from the stratosphere, which risk on Earth would increase most?
Answer and explanation
Correct answer: Effect of harmful ultraviolet radiation
Option A is correct because stratospheric ozone absorbs a substantial part of the Sun’s harmful ultraviolet radiation, especially UV-B. Without this protective layer, more ultraviolet energy would reach Earth’s surface, increasing risks such as skin damage, eye injury, and harm to plants and aquatic organisms. Tides, seismic-wave speed, and magnetic-pole movement are controlled by different physical systems.
