Hi, Kamron– }} >> Bore threw the continent? I have no idea what you're talking about here either. << }} Yes… thats the explanation of volcanic activity away from the "subduction zone" the melting crust dissolves the lithosphere and arrives at the surface If an ice sheet is pushed or pulled underwater at roughly a 45 degree angle, bubbles trapped in the ice when freed by melting might rise straight up instead of angling to follow the "weakness" made by ice penetrating water. I am fuzzy on whether magma bubbles would be mostly generated so deep that they would establish their rising direction in the realm of plasticity. –Doug
