Glacier - A large, perennial accumulation of ice, snow, rock, sediment and liquid water originating
on land and moving down slope under the influence of its own weight and gravity; a dynamic river
of ice. Glaciers are classified by their size, location, and thermal regime.
bergschrund (from the German for mountain cleft) - a crevasse that forms where a moving glacier
ice separates from the stagnant ice or firn above
firn - ice that is at an intermediate stage between snow and glacial ice
cirque - a mass of ice and snow that forms in a hollow, semi-circular area of rock
moraine - material transported by a glacier and then deposited. There are eight types of moraine,
six of which form recognizable landforms, and two of which exist only whilst the glacier exists.
riegel - bedrock that have been exposed by glacial erosion
crevasse - a deep crack in an ice sheet or glacier (as opposed to a crevice, which forms in rock)
serac - a block or column of ice formed by intersecting crevasses on a glacier
glacial tongue - the first part of a glacier that is shaped like a tongue
