Which risk increases when differential pressure forces magma into forming volcanic domes underneath a glacier?

A)Accelerated ice sheet basal sliding
B)Decreased regional geothermal activity
C)Diminished subglacial lake development
D)Reduced sediment deposition rates

💡 Explanation

Accelerated ice sheet basal sliding increases because the increased pressure melts the ice directly above the dome, causing enhanced lubrication at the ice-bedrock interface due to pressure melting, therefore promoting ice flow rather than diminishing geothermal heat.
