Abrasion
A process of erosion involving the wearing away of the valley floor and sides
1 of 22
Plucking
A process of glacial erosion where individual rocks are plucked from the valley floor and sides as water freezes them from the glacier
2 of 22
Rotational Slip
Slippage of ice along a curved surface
3 of 22
Moraine
Sediment carried and deposited by the glacier
4 of 22
Bulldozing
the pushing of deposited sediment at the snout by the glacier as it advances
5 of 22
Hummock
A small area of raised ground, like a molehill
6 of 22
Corrie
A deep depression on a hillside with a steep back wall, often containing a lake

Glacial trough
a wide, steep sided valley eroded by a glacier

this shows the changes in height and shape along the length of the glacier.

Lateral Moraine
A ridge of sediment running alongside the edge of a glacier where it meets the valley side
15 of 22
Medial Moraine
a ridge of sediment running down the centre of a glacier - formed when two glaciers meet
16 of 22
Terminal Moraine
A high ridge running across the valley representing the maximum advance of a glacier
17 of 22
Drumlin
An egg- shaped hill found on the floor of the glacial trough

Fragile Environment
An environment that is easily unbalanced and damaged by natural or human factors

Avalanche
A rapid downhill movement of a mass of snow, ice and rocks usually in a mountainous environment
20 of 22
Loose snow avalanche
A powdery avalanche usually originating from a single point
