Description:

This investigation explores the basic process of isostasy and its explanatory power for the observed bimodal distribution for global elevations. In Part A, the densities of representative rock samples of granite and basalt are determined experimentally and compared to typical crustal values. In Part B, the concept of isostasy is examined through a continent-to-ocean transect by determining if the hydrostatic pressure at a common asthenosphere depth is approximately equal under four different "columns" of overlying material. In Part C, a dynamic web-based isostasy model is used to predict elevations for lithospheric columns of different crustal thickness and density. In Part D, the bimodal distribution of global elevations is explicitly explored and connected to the fundamental components of isostasy as explored in Parts A, B, and C.
