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.

This Flash animation illustrates aeolian processes that form terrestrial arches. Erosion exploits tectonic fractures and results in thin sandstone walls that can be penetrated by near ground windblown sand grains. Over time, weathering and gravity causes arches to fall. Users can stop, play, fast forward and rewind the animation at any time. This visualization is one of several animations in a series ... Full description.

This site has links to three Flash animations about geologic processes. Topics of the simulations are sediment transport modes, meander cut-offs and oxbow lakes, and flood plains and stream terraces. These visualizations are from Chapter 10 (Streams and Floods) of the animations section of the Online Learning Center for the McGraw-Hill textbook Physical Geology, 9th edition (ISBN: 0072402466) by Plummer, ...

This site provides students with mathematics self-study material which is embedded within the context of the geosciences. The material consists of many MathHelp "notebooks" covering specific mathematical topics related to a relevant geological context, such as plate velocity or cliff erosion. The notebooks contain explanations, illustrations, and examples. A mathematical glossary is also constantly ... Full description.

The Mineral Gallery is a constantly growing collection of mineral descriptions, images, and specimens, together with several ways of accessing these descriptions. For each mineral there is a photograph, description, and a list of physical characteristics. This mineral database is searchable by name, mineral class or by keyword. There is also useful background information about mineral properties. ... Full description.

This site is devoted to microscopic images of minerals, thin sections of rocks and meteorites, and stereoscopy of minerals. The site is organized into the following categories: meteorites, plutonic rocks, volcanic rocks, carbonates, sedimentary rocks, sedimentary rocks and diatoms. Other links include conoscopic images, an index measurement page containing theoretical information about index of refraction ... Full description.

This module is designed to allow students to learn about igneous rocks at their own speed using images of hand samples and rock outcrops in their natural settings. Topics covered include the common igneous rock types, igneous textures, and intrusive rock bodies. Each topic has instructive text and several images. The site also features a self-quiz with 17 questions about 12 hand sample pictures. This ... Full description.

Rob's Granite Page contains mineral identification in granites, pictures of various granites, general information about granite, and links to studies of granite and other igneous topics. There is extensive information on the Llano Uplift in Texas. This resource is part of the Teaching Petrology collection. http://serc.carleton.edu/NAGTWorkshops/petrology03/index.html Full description.

This site is the homepage for a petrology class. The primary feature of this site is a comprehensive set of lecture notes. There are 18 separate lectures encompassing igneous and metamorphic petrology and related topics. Lectures include text, figures, maps, and tables, and are available in either HTML format or as PDF files. This resource is part of the Teaching Petrology collection. http://serc.carleton.edu/NAGTWorkshops/petrology03/index.html ... Full description.

These lecture notes provide an introduction to igneous rocks. The notes cover information about characteristics of magmas, plutonic rocks, volcanic rocks, and textures of igneous rocks. There are several illustrations within the text. This resource is part of the Teaching Petrology collection. http://serc.carleton.edu/NAGTWorkshops/petrology03/index.html Full description.
