- Glacial Landscapes
- Glacial Deposition
- Drumlins= elongated hills of glacial deposits. They can be 1 km long and 500 m wide
- Crag and Tail= rocky hill or mountain, generally isolated from other high ground
- Erratic= large rocks or
boulders in unusual shapes, unusually large and of a rock type uncommon to the
area they have been dumped and so are found on their own.
- Boulder Clay= A deposit of clay, often full of boulders, formed from the ground moraine material of glaciers and ice-sheets
- Moraines= When glacial ice melts, different types of rock are laid down that have been carried along by the glacier
- Recessional= ridge of debris deposited when the glacier pauses during retreat
- Lateral= found deposited along the sides of the glacier.
- Terminal= found at the the furthest (end) point reached by a glacier.
- Medial= found at the junction between two glaciers.
- Push= disorganised piles of rocks of various shapes, sizes and of differing rock types.
- Recessional= ridge of debris deposited when the glacier pauses during retreat
- Till or glacial till is unsorted glacial sedimen
- Drumlins= elongated hills of glacial deposits. They can be 1 km long and 500 m wide
- Erosion
- Fjord= deep, narrow and elongated sea or lakedrain, with steep land on three sides
- Tarn= A tarn is a mountain lake, pond or pool, formed in a cirque excavated by a glacier
- Nivation Hollows= erosion of the ground beneath and at the sides of a snow bank
- pyramidal peak= where three or more corries and arêtes meet
- Arete= Tributary glacier left high above the main valley
- Glacial troughs= Glaciers cut distinctive U-shaped valleys with a flat floor and steep sides
- Roches moutonnée= steep, jagged faces and a smooth gradual incline. May have striations
- Hanging Valley= a valley which is cut across by a deeper valley or a cliff
- Ribbon Lakes= a ribbon lake is a long and narrow, finger-shaped lake
- Truncated Spurs= a ridge that descends towards a valley floor or coastline from a higher elevation, that ends in an inverted-V face
- Roches moutonnée= steep, jagged faces and a smooth gradual incline. May have striations
- Corries, cwms or cirques= the starting point of a glacier
- Fjord= deep, narrow and elongated sea or lakedrain, with steep land on three sides
- Glacial Deposition
