Apply Inquiry and Review the Big Idea

18. Sample answer:  Anish is modeling erosion and deposition by moving water.  Some of the sand will move, or be eroded by the poured water.  If one end of the pan is propped up, the water will carry most of the sand to the lower end of the pan, where it will be deposited, or dropped.

20.  The water represents the partly melted portion of Earth’s mantle.  The pieces of foam represent plates.  If the foam pieces were placed on the water’s surface and the water in the beaker were heated, convection currents would form and cause the foam plates to move over the water’s surface.
