What Happens When A Volcano Meets a Glacier?

The video explores the interaction between glaciers and volcanoes, highlighting how glaciers can suppress volcanic activity by exerting pressure on the Earth's mantle. During the last Ice Age, glaciers covered a significant portion of the Earth's surface, leading to a volcanic dry spell. The video explains how glaciers prevent magma from rising by maintaining pressure, even at tectonic seams. After the Ice Age, volcanic activity surged as glaciers melted, particularly in regions like Iceland. The video concludes by suggesting that future glaciations could again suppress volcanic activity, illustrating a dynamic geologic interplay.
