Material Detail

This site features Flash and QuickTime animations related to groundwater. They contrast the permeability of gravel, sand, silt, and clay, as well as the speed of groundwater movement in rivers, lakes, and aquifers. They also outline the hydrologic cycle, discussing infiltration, percolation, and the water table, exhibit groundwater overdraft and the resulting formation of a cone of depression, and show how groundwater entering fractured bedrock can become superheated and pushed to the surface, erupting as a geyser. The animations can be paused and rewound to stress important points. These resources are suitable for use in lectures, labs, or other teaching activities.
