A
Erosion
Entrainment
Transport
Deposition
2
Q
Glacial process erosion
A
Removal of weathered material by glacial ice includes plucking, abrasion, crushing and basal melting
3
Q
Glacial process entrainment
A
Small rock fragments trapped (entrained) by basal ice freezing around them and applying sufficient drag to pull them along
4
Q
Glacial process transport
A
Rock debris transported on ice surface (supraglacial) within ice (englacial), and base of ice (subglacial)
5
Q
Glacial process deposition
A
Till is sediment deposition directly by glacier ice. Fluvio-glacial debris is deposited by glacial meltwater
6
Q

Plucking
