    Airy and Pratts hypothesis are both shows local compensation depth. Airy :- suggest all the crustal density is constant,but where the height of mountain is high there must be a great deep root to balance ,weight of mountain mass creating a density difference . Pratts:- he suggest that density is not constant, laterally it varies and here the compensation depth is a flat line below crust and in the boundary of crust ,mantle . so the less dense column will have high height of mountain. formulas and figure below.
