Sand Everywhere 3

Glaciers are another good sand maker. The heavy ice scrapes and grinds the rocks that it moves across. In addition, the ice carries along the sand it has made and dumps it in places far away. Another great sand maker is the  ocean. All over the world the tides rise and fall and storm waves tear at the rocks along the shore banging them down until finally some of the rocks are so small that they are what we call sand.
