Fluvioglacial Landforms

Question 1

Kames

Answer 1

Form at the front of a melting ice sheet, typically unsorted.
Kame terraces are the most extensive as they are formed by infilling marginal glacial lakes
Kame deltas are mound shaped hills on the valley floor as a melt water stream enters a marginal lake
Crevasse kames are formed in a crevasse as melt water deposits sediment inside

Question 2

Eskers

Answer 2

Large ridges formed under a glacier by a meltwater stream, they are parallel to the direction of ice flow

Question 3

Outwash plains

Answer 3

At the end of a glacier where all of the sub glacial sediment is deposited, it is sorted with large sediment closer to the front of the glacier

Question 4

Braided stream

Answer 4

Formed on an outwash plain if there is variable meltwater discharge, creating many river passages that can dry up
