Isostatic models

Three principal models of isostasy are used:
   The Airy-Heiskanen Model
- where different topographic heights are accommodated by changes in crustal thickness.
   The Pratt-Hayford Model
- where different topographic heights are accommodated by lateral changes in rock density.
   The Vening Meinesz Model
- where the crust acts as an elastic plate and its inherent rigidity spreads topographic loads over a broader region. This hypothesis was put forward to explain how feautures of grand magnitude like the himalayas could be explained using a regional isostatic compensation rather than a localised one which is the case for the first two models.
