From Cutting Edge
Part of the supporting resources for the School of Earth Sciences dynamic earth module, the -Why Topography?- site discusses two models introduced in the 19th century that are still used to explain topographic variations. These models are the Pratt and Airy models of isostasy. In the Pratt model, high topography (relative to surroundings) is due to lower density whereas in the Airy model, high topography is due to thick crust.
