The surface of the Earth, or more specifically the mountain side that has been covered with ice that over time will expand more and more, will change in shape significantly over longer period of time.
The change will be manifested in the mountain side becoming very steep, sharp, pointy, looking, and that will be due to the erosion caused by the ice on it, which essentially will a glacial erosion, since that ice will be a glacier on the mountain side.
The change in the landscape will be seen only after the glacier melts and uncovers its effect, but while the mountain side is covered with it, it will not be easy to witness the change.
