glacial processes

Question 1

types of erosion

Answer 1

abrasion and plucking

Question 2

abrasion

Answer 2

ice includes angular forst shottered material which scours the landscape - large rocks carried below the ice often scratch the bedrock to form striations

Question 3

plucking/quarrying

Answer 3

meltwater freezes part of the underlying bedrock at base of glacier and any loosened rock fragments are pulcked wawy as the glacier slips forward

Question 4

3 types of glacial transportation

Answer 4

supraglacial = mianly weathered material carried on top of the ice
englacial = formally supraglacial material is now buried by fresh snowfall and carried within ice
subglacial = material carried below ice, which is dragged and pulversied by overlying glacier

Question 5

depostion where it happens

Answer 5

depostion of sediment is transported by ice, ouccring when it melts mianly in the ablation zone away from the ice
