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 ...

This Flash animated slide show illustrates the development of a waterfall by demonstrating the way that soft rocks are more quickly eroded downstream than hard rocks. The animation also reveals the way rapids, steep backwalls, plunge pools, overhangs, and gorges develop as well as the way waterfalls retreat up stream. The user can navigate backwards and forwards within the slide show. This is one ... Full description.

This site features a narrated QuickTime animation of graded streams. It discusses relationships between stream water level and high and low water velocity, erosion, bedload transport, deposition and floods. This visualization is from Chapter 17 (Fluvial Processes and Landforms) of the animations section of the Instructor Companion Site for the Wiley Higher Education textbook (ISBN 0-471-23800-7) Physical ...

This Flash animated slide show with accompanying audio illustrates the evolution of an alpine environment from a fluvial V shaped valley landscape to a glaciated U shaped valley landscape. It also shows the advance and regression of glaciers and the reestablishment of post glacial streams and hanging valleys. This visualization is from Chapter 20 (Glacier Systems and the Ice Age) of the animations ... Full description.

This interactive Flash animation of a dune triangle allows users to click on a dune type and see a related image with accompanying descriptive text. The three parameters of the dune type triangle are sand, wind, and vegetation. The demonstrated dune types are longitudal, crescent (barchan), transverse, star, and parabolic. This visualization is from Chapter 19 (The Work of Waves and Wind) of the animations ... Full description.

This site has links to two Flash animations. Evolution of Basin and Range Landforms demonstrates fault movement and subsequent sediment erosion and deposition that create mountains and valleys. Formation of a Sand Dune illustrates sand grain erosion, transport, and deposition from the windward to leeward side of a dune. These visualizations are from Chapter 13 (Deserts and Wind Action) of the animations ... Full description.
