Glaciers, which cover about 10 percent of Earth's land surface and hold between two and three percent of its water, are found on every continent except Australia. This interactive activity adapted from the National Park Service offers a comprehensive introduction to glaciers. By exploring the different sections, users will learn where and why glaciers form, what influences their growth and decline, and how an apparently solid mass appears to flow like a river.
This media asset was adapted from Views of the National Parks: Glaciers Knowledge Center by the National Park Service.
