Types of Glaciers: Ice Sheets, Valley, Piedmont, and More

Ice sheets are continent-scale glaciers over 50,000 km2. Only two exist: Antarctica and Greenland. Valley glaciers flow through mountain valleys.

Piedmont glaciers spread out on flat plains. Ice caps are dome-shaped and smaller than sheets. Tidewater glaciers terminate in the ocean.

Ice shelves are floating extensions. Surge glaciers periodically advance rapidly..
