← GeographyWhich outcome occurs when excessive airborne tephra blankets Arctic ice?
A)Accelerated glacial ice surface melting✓
B)Increased albedo due to light scattering
C)Declined permafrost carbon sequestration rate
D)Suppressed phytoplankton oceanic photosynthetic activity
💡 Explanation
Increased surface absorption of solar radiation results because decreased reflectivity drives positive feedback acceleration of the Ice-Albedo Feedback mechanism; therefore, ice surface melting accelerates rather than light reflection, because darker particles increase heat absorption.
