Term: | Moraine |
Definition: | Mounds, ridges or deposits of rock debris transported by a Glacier (glacial till). Common forms are: ground Moraine formed under a Glacier; lateral Moraine, along the sides; medial Moraine, down the centre; and end Moraine, deposited at the foot. Moraines are left after a Glacier has receded, providing evidence of its former extent. Moraines can have frozen cores and exist in Permafrost environments. On steep slopes such Moraines can show signs of Creep. |
