Soil Texture and Classification
This interactive site from North Carolina State University shows the kinds of soils developed from different silt, sand, and clay content levels. A ternary diagram shows the range of soil textures based on percentages of each component. The site also provides an example of how to determine the soil texture of a sample composition. Students are also able to enter the percent composition of sand, silt, and clay and predict the soil texture classification themselves.
Crystal Growth Movies (title enhanced by cataloger)
This site, maintained by the Department of Geology and Geophysics at the University of Wyoming, contains four QuickTime videos of actual crystal growth. To access the videos, scroll down to the bottom of the page and click on any of the downloads that are available. These videos enhance understanding of the processes involved in crystallization.
Sediment Transport Movies
This site features a collection of 25 freely downloadable brief movies that demonstrate different types of sediment transfer processes in a variety of environments. Videos present both live and laboratory-created conditions and events such as turbidity currents, debris flows, tidal fluctuations, and the formation of dunes and ripples. For example, two live videos by Canadian sedimentologist Gerard Middleton show the effects of tidal processes at the Bay of Fundy, Nova Scotia. There are also four videos which capture the growth of mineral crystals. Text to accompany the videos can be downloaded as a PDF file by clicking the appropriate link.
IRIS: Seismic Monitor
This web site provides an interactive map of global seismic activity that is updated every 30 minutes. The site uses data from the National Earthquake Information Center to produce a world map with clickable areas of seismic activity. Users can click on geographical areas of the map, and will be taken to a table which describes the time, location, magnitude and comments about particular seismic events. Information is kept for earthquakes that have occurred in the last 24 hours, 15 days, and five years. For earthquakes of a magnitude of 6.0 and over, links are provided to special information pages that try to explain the where, how and why that particular event occurred. The user can also view the ground motion associated with an event and visit seismology laboratories around the world.
Surface Area vs. Size and Shape
This annotated animation shows the potential increase in surface area which results from physical weathering. Students have the opportunity to calculate and compare surface area increases for two different scenarios: when a single mass weathers into cubical blocks versus plate-like blocks. Captions help students through calculations for determining the total surface areas of the different shapes.
Dryland Rivers Research
This site is intended to stimulate research by providing an information focus and provoking networking between those working on dryland rivers and the sediments they leave behind. Topics covered include processes and products, hydrology, dynamics, architecture of rivers and their floodplains, adjacent and interacting processes, modern and ancient dryland rivers and integration of geomorphology and sedimentology. Users may follow links to dryland river descriptions and myths, hot topics, a discussion forum, images and other useful information.
Minerals in Earth's Mantle
This image from the COMPRES galleries shows the various mineral species that make up the composition of the mantle and how that composition varies with depth down to the core-mantle boundary.
Capabilities of Experimental Apparatus
This diagram displays the pressure/temperature conditions capable of being simulated with two types of experimental equipment: Piston-Cylinder and USSA-2000. The ranges of conditions are plotted on a cross section of the deep Earth for comparison.
