During the Wisconsin Episode Glaciation, a glacial forebulge formed just off the coast of British Columbia in the vicinity of Queen Charlotte Island. What is a glacial forebulge and how did this one form?
What will be an ideal response?
Answer: A glacial forebulge forms when a massive ice sheet pushes down on the crust. This pushes down on the upper mantle, which responds by moving mantle material away from the glacier and out in front of the ice sheet where the pressure is less. As a result, the mantle bulges upward along the margins of the glacial ice.
