← GeographyWhich climatic effect results when volcanic aerosols remain suspended in atmosphere after large eruption?
A)El Niño Southern Oscillation intensification
B)Global mean surface cooling anomaly✓
C)Stratospheric ozone layer depletion
D)Regional precipitation pattern stabilization
💡 Explanation
When volcanic aerosols are suspended, they increase Earth's albedo because sulfate aerosols reflect incoming solar radiation, leading to a decrease in temperatures and creating a negative radiative forcing. Therefore, a global cooling anomaly results, rather than ENSO intensification, ozone depletion, or precipitation stabilization, which each involve separate atmospheric processes.
