This is known as glacial erosion. Simply put, glacial erosion is the curving and shaping of the land beneath a moving glacier. Glacial Erosion Glaciers erode the underlying rock by abrasion and plucking. Glacial meltwater seeps into cracks of the underlying rock, the water freezes and pushes pieces of rock outward. The rock is then plucked out and carried away by the flowing ice of the moving glacier (Figure below).
