A glacier helps to form a valley in two ways. When the glacier moves through an area, it scrapes the land and pushes dirt in front of it, making a larger and larger hole that eventually becomes a valley. Runoff from the glacier as it melts also helps, as it carries soil away from the area, digging out a valley.
