	REVIEW: The U.S. Geological Survey (USGS), which is the largest earth science research and information agency in America, is part of the U.S. Department of the Interior, and was established to provide a permanent Federal agency to "conduct the systematic and scientific classification of the public lands and examination of the geological structure, mineral resources, and products of the national ' domain'." On this website you'll find maps, databases, descriptions and analyses of the surface, underlying geologic structure and dynamic processes of the earth. The main page has links to sections on biology, geology, mapping, water, hazards (such as earthquakes, floods, landslides, tsunamis, volcanoes and geomagnetism), natural resources, environment, information management and the Department of the Interior. Additionally, the site is searchable and has an entire section devoted to K12 education. "The Learning Web" provides teachers with activities and lessons that have been reviewed by teachers and students. This site provides current and useful information on topics for geography, earth science, biology, environmental science, life science, meteorology, oceanography and possibly other discipline teachers, educators and students. Even viewers currently not connected to school will find a lot of fascinating information here from fun to technical. Very interesting site.
