Isostasy and Gravity
Compiled by Jeff Crabaugh at Carleton College (SERC) and the University of Wyoming
This section highlights animations, interactive graphics, and static images used to illustrate the concept of isostasy and to show how measurement of gravity over mountain ranges provides evidence that mountains have deep roots.
What is Isostasy?
Isostasy and Postglacial Rebound. (more info) Animations, static diagrams, and photos are used to depict the isostatic adjustments associated with the emplacement and removal of ice sheets. From the website of William W. Locke (Montana State University).
Isostasy and Postglacial Rebound. (more info) From the Dynamic Earth website at the University of Leeds, simple and clear interactive graphics illustrate how two models of isostasy have been used to explain variations in topography.
Evidence for Mountain Roots: Gravity
Mountains, Weathering and Erosion. (more info) A detailed description of weathering; both physical and chemical, erosion and mass wasting. Rich with example images of landforms and weathering products.
Mountains, Weathering and Erosion. (more info) A detailed description of buoyancy, Archimede's principle, and evidence for mountain roots. Includes mathematical and graphical examples of buoyancy and gravity.
