← ScienceWhich consequence results when ultraviolet radiation causes bond disruption in molecular oxygen?
A)Formation of stratospheric zone layer✓
B)Increase in tropospheric greenhouse gasses
C)Destruction of the thermosphere
D)Rise in ground-level air pressure
💡 Explanation
The breakdown of O₂ molecules by ultraviolet light's bond disruption leads to free oxygen radicals which react to form O₃ via the Chapman cycle; therefore, the ozone layer forms in the stratosphere, rather than causing global warming or atmospheric destruction.
