WebIsostacy. Isostasy (Greek isos “equal,” stasis “stand still”) is a term in geology, geophysics, and geodesy to describe the state of mass balance (equilibrium) between the Earth’s crust and upper mantle. It describes a condition to which the mantle tends to balance the mass of the crust in the absence of external forces. WebJan 1, 2001 · 1.12 Success of the Airy and Pratt Models of Isostasy in.

The case of Te = 0 describes local (Airy or Pratt) isostasy, where loads are compensated in hydrostatic equilibrium only, without mechanical support. led wedding
