Depositional Landforms

Question 1

Terminal moraine

Answer 1

High mound extending across the valley to mark the maximum advance of the ice sheet

Question 2

Lateral moraine

Answer 2

Derived from frost shattering of the valley sides, carried at the edge of the glacier - on melting a side embankment is formed

Question 3

Recessional moraine

Question 4

Erratics

Answer 4

Picked up and carried by ice

Deposited in areas of different geology

Question 5

Drumlins

Answer 5

Smooth, elongated mounds of till ( unsourced rock,clay and sand deposited by ice

50m high and over 1km in length

Smoothed by abrasion with a steep upstream side and a gently sloping downside

Form a swarm

Question 6

Till sheets

Answer 6

Found behind terminal moraine in low-lying areas

Wide areas of flat relief with a covering of glacial till

Variable in composition, dependent on the nature of the rocks over which the ice has been moved.
