How do glaciers change the land they cross?

Glaciers do sidewards cutting unlike River which does downwards cutting. When Glaciers move they generate a lot of friction on the walls of their glacial bank and erode the soil from sides.The phenomenon can take years and completely change the topology.

Ideally glaciers should not cross any land. They must remain wherever they are and not move. They may shrink in summer and expand in winter. But stay put they must. If they were to move and cross any land their heavy weight could crush everything under them on the path they take.
