What Causes a Glacier to Move?

Glaciers move because they're like big, slow slushies on ice. When snow falls and turns into ice, it pushes the glacier forward, just like when you push a heavy block of ice on your kitchen floor. Sometimes, the ice slides over rocks underneath, helping it move even more slowly.
