These websites are about glaciers. Learn what a glacier is, how they are formed, and the impact that they have on the landscape. See maps of where glaciers once covered large areas of North America and pictures of landforms that were created by glaciers thousands of years ago. There are also classroom experiments and activities for deeper understanding of how glaciers behave.
Find out about glaciers and glacial formation. After you've read about the different types of glaciers, advancing and retreating glaciers, and the effects of global warming on glaciers, try a short quiz to test what you've learned.
