Identify the contents of a glacier like those found in Patagonia. Construct a mini glacier model in class. Compare and contrast the classroom model with Patagonian glaciers. They move very slowly. There are several types of glaciers such as the Outlet valley glacier, a Cirque glacier, and Alpine valley glacier and a Piedmont glacier.
Glaciers form in mountains and move down mountain valleys until they melt.
The ice cracks during this movement down the valley . These cracks are called crevasses. Glaciers that are found in valleys and flow down old or current river valleys and move via gravity are called Outlet valley glaciers. Much smaller glaciers that form in high mountains and then flow down to the valley are called Cirque glaciers. Alpine glaciers are where several Cirque glaciers meet.
