← GeographyWhich risk increases to stratospheric ozone when polar vortex weakens?
A)Increased PSC formation rates✓
B)Decreased UV radiation absorption
C)Enhanced tropospheric condensation events
D)Reduced meridional heat transport
💡 Explanation
Increased PSC formation occurs because a weaker polar vortex allows warmer air to penetrate, altering local atmospheric composition and temperatures which initiate increased Polar Stratospheric Cloud (PSC) formation, therefore increasing ozone depletion rather than changes to absorption.
