WebErosion processes in a glacier WebPieces of rock are transported to the front of a glacier as ice within the glacier moves. Will plucking occur if a glacier is NOT advancing? Yes, because glacial ice is still moving inside the glacier even if the glacier's front is not advancing. __________ are defined as a chain of glacial lakes where each lake flows into the next.
