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. . . a. . . q. .

A distinctive suite of basin develops where plates rift and separate as a result of sea floor spreading. Continental margins under these conditions are referred to as “divergent” or passive margin .
