The height of the top of the block (iceberg, continental crust) would be h. m. ’ + h. c. Response of the crust to a addition of a load (sediment accumulating or a large volcano): the crust “floats” downward to re-establish isostatic equilibrium and the elevation of the crust changes less that the thickness of the material added. .
