When the large sheets of sea ice are formed, they exist in one of two formations. Fast ice, or land-fast ice, refers to the large, solid ice sheets that are attached to land. The pack ice consists of the smaller, free-floating pieces of sea ice. They may have formed independently, or may have broken off from the fast ice (Figure 14.1.3).
