what is lateral moraine
Answers
Answer:
A lateral moraine forms along the sides of a glacier. As the glacier scrapes along, it tears off rock and soil from both sides of its path. This material is deposited as lateral moraine at the top of the glacier's edges.
Answer:
Lateral moraines occur widely in the Cairngorms. They tend to be quite small features and are often best seen after light snowfalls, sloping down-valley. Good examples occur in middle Glen Feshie and in the Lairig an Laoigh, by Fords of Avon.
Explanation:
Lateral moraines are a product of rock fall onto the margin of a glacier. Rock fall is a result of frost weathering of the rock wall and of over-steepening of the cliff by glacial erosion, leading to rock slope failure. The rock debris is carried along the glacier edge as it moves towards the snout. Melting of the glacier leaves a ridge or bench made of blocky debris on the flank of the valley. Lateral meltwater channels may also be developed.
