[单选题]回答 64 ~ 67 题：A volcanlc ctuption in iceland has sent ash zcross northern Europe .Airlines have Stopped or changed the flights across the Allantic Ocean , leaving hundrede of passengets stuck in aipports.Grimsvotn is one of the largest and most active volcadoes in Europe. What makes Grimsvom different is that it lies under a huge glacier(冰川) of ice up to 12 maters thick. The hot volcano heats up the ice above it, which then forms a layer(层)of water between the glacier and the volcano This layer of water puts pressure on the volcano, keeping it stable, As the water flows out from under the glacier, the pressure lifts. The lava(岩浆) from the volcam then comes up to the surface. This is exactly what happened today.

It is below ice.
