Glacial mass is a term used to describe a large body of ICE, usually found in the polar regions. The term can be broken down into three parts: SERAC (5 letters), ICE (3 letters), and ICECAP (6 letters). A serac is a large block of ICE found on a glacier, while ICE is a frozen form of water. An icecap is a large dome of ICE that covers a large area of land or sea. Together, these three components make up a glacial mass.
