WebApr 12, 2024 · A model to account for isostasy which in the lithosphere assumes a constant density (ρ c = 2 670 kg/m 3), but in which topographic elevations (h) are compensated by the presence of ‘roots’ replacing high-density mantle rocks (ρ m = 3 300 kg/m 3) by lower-density lithospheric rocks.The depth of the root (d) is equal to hρ c /(ρ - ρ c).See also pratt model.

WebSep 7, 2024 · Answer: Difference between Pratt isostasy and airy isostasy is described as follows:-. Theory of isostasy in terms of Pratt's concept assumes lateral alteration occurring in density of rock over lithosphere whereas rock density is assumed to be almost equal over lithosphere in Airy s concept.

WebTherefore, understanding the dynamics of isostasy helps us figure out more complex phenomena such as mountain building, sedimentary basin formation, the break-up of continents and the formation of new ocean … WebOct 16, 2024 · Nevertheless, Pratt-style compensation is thought to apply at mid-ocean ridges, though with the density increase away from the ridge occurring in the subcrustal … 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. end of a verbal citation crossword
