Question:
A crustal block with mean density 3000 kg m^3 is initially in is ostatic equilibrium with the surrounding rocks whose density is 3200 kg m^3, as in the figure
(a). After subsequent erosion the above-surface topography is as shown in
(b). The distance L remains constant (i.e. there is no erosion at the highest point A) and Airy-type isostatic equilibrium is maintained. Calculate in terms of L the amount by which the height of A is changed. Explain why A moves in the sense given by your answer.
