What are Glaciers and How Do They Move? 

Glacier science, simplified. Today we're talking about glaciers: what is a glacier? How do glaciers move? Did you know they are often called "rivers of ice"? To prepare for an upcoming video on Glacier National Park, we first have to understand glaciers themselves. In this video we look into the definition of a glacier (it's much more than a hunk of ice!), how glaciers form, and two primary ways that glaciers move (yes, they move!).
