← GeographyWhich outcome is accelerated along fjord coastlines during repeated freeze-thaw cycles?
A)Increased rates of rock weathering✓
B)Amplified thermohaline circulation strength
C)Enhanced salt marsh sediment accumulation
D)Accelerated chemical equilibrium of sediments
💡 Explanation
Increased rates of rock weathering occur because **frost wedging** exploits pre-existing cracks in fjord walls; repeated freezing expands ice, therefore physically dislodging rock fragments, rather than altering ocean circulation, sediment or chemical equilibrium.
