i) - two adjacent hallows on a mountain side
- the two hallows are filled with ice
- the ice erode the side through plucking and deepens the hollow through abrasion
- through erosion, the back walls of the hollows slowly recede
- eventually the hollows(cirques)are separated by a knife-edge ridge
- the ridge is called an arête
ii) - a large block of rock stands on the path of on-coming glacier
- the ice plucks off /erode rock fragments from the upper side of the block
- as the ice moves round and over the resistance rock, it carries the eroded materials to the lee-ward side
- the lee side does not experience erosion
- deposits materials on the lee-ward and together with weak rocks forms
- flat corridors separate them from each other
- they occur I groups
- the width of the corridors vary from 25m to 50m
- where the wind blows from the same direction for long, dunes become gentle on the wind ward and steep on the lee ward
