← GeographyWhich risk increases when prolonged tephra burial inhibits plant growth?
A)Nutrient cycling effectiveness declines substantially✓
B)Surface albedo reflects solar radiation
C)Oxidation drives rapid rock weathering
D)Haloclines strengthen deep ocean oscillations
💡 Explanation
Nutrient cycling diminishes because plant biomass inputs and decomposition pathways are suppressed significantly. Reduced bioturbation decreases nutrient mobilization; therefore, the soil nutrient availability is curtailed, rather than increased radiation reflection alone.
