Ice tongue

An ice tongue or glacier tongue exists when there is a narrow floating part of a glacier that extends out into a body of water beyond the glacier's lowest contact with the Earth's crust. An ice tongue
The Erebus Glacier Tongue, coming off the Erebus Glacier from 3,800 m (12,500 ft). Mount Erebus, Ross Island, Antarctica. The ice tongue is protruding into McMurdo Sound (frozen in this image).

The Erebus Glacier Tongue is a mountain outlet glacier and the seaward extension of Erebus Glacier from Ross Island. It projects 11 kilometres into McMurdo Sound from the Ross Island coastline near Ca
Ice tongue
…or by melting. Icebergs are often formed when ice tongues break off in part or wholly from the main glacier. A few examples of ice tongues are the Erebus Glacier Tongue, Drygalski Ice Tongue, and Thwaites Ice Tongue. Early theoretical work by Gordon Holdsworth described how an ice tongue bends when tidal oscillations…
The Erebus Glacier Tongue is shaped by a variety of forces such as wave action during summer thaw, tides, and internal tensions.
Crevasses covered with snow and ice are exposed as ice caves on the seaward edges of the Erebus Glacier Tongue.
Gravity, slope, and friction are among the factors that affect the flow ice streams such as the Erebus Glacier Tongue. Scientists as early as 2003 identified a correlation between lunar tides and ice stream movement.
