NOVA: Descent into the Ice

This NOVA website presents engaging materials on glaciers and the exploration of France's Mt. Blanc. Students can find a compelling account of why melting glaciers are as significant as other threatened natural resources such as old growth forests and coral reefs. The site features a slide show depicting how satellite imagery assists in glacier hazard assessments. Users can take a virtual tour of the gear ice climbers need in order to explore isolated ice shafts at some of the highest elevations on Earth. The tutorial, Life Cycle of a Glacier, takes visitors through the life of a snowflake -- from the time it forms in the sky and falls on the glacier until it finally becomes incorporated with an iceberg, melts, and again evaporates into the atmosphere. Teachers will find a fun activity for students to learn about water changing into ice. This site is also reviewed in the July 23, 2004 _NSDL Physical Sciences Report_.
