Deformed ice

General term for compressed ice.

General term for ice that has been compressed and, in some cases, has moved up or down vertically in response. Types of deformation include overlapping ice, compressed ice and pressure ridges.

When sheets of sea ice collide to form pack-ice hummocks, only one-tenth of the ice mass can be seen above the surface; the remaining nine-tenths are hidden underwater, often extending into the depths like a ship’s keel.
