WebLocal isostasy is an idealized description of how lithosphere floats on underlying fluid asthenosphere (Watts, 2001). The term ‘local’ implies that the surface elevation at a point depends only on the average density of the column of lithosphere below that point. Essentially, the shear stress on vertical planes is taken to be zero. Web1.e. the core is more dense than the mantle 2.b. the inner core is solid nickel-iron 3.b.
