Explanation:

The movement of glaciers is slow, unlike water flow and results in the formation of typical landforms: ? Cirques are the most common of landforms in glaciated mountains. The cirques quite often are found at the heads of glacial valleys. The accumulated ice cuts these cirques while moving down the mountain tops. They are deep, long and wide troughs or basins with very steep concave to vertically dropping high walls at their head and sides. A water lake is often seen within the cirques after the glacier disappears. Such lakes are called cirque or tarn lakes. There can be two or more cirques, one leading into another below in a stepped sequence. ? Arete is a narrow, sharp ridge that separates two cirques, or glacial valleys. It forms when two glaciers erode parallel valleys on opposite sides of a mountain or ridge. As the glaciers erode the rock, they leave behind a sharp crest that is steep and often has serrated edges. ? Truncated Spurs are elongated ridges that extend outward from the sides of a glacial valley. They are formed when the glacier erodes the sides of the valley, leaving behind triangularshaped landforms that jut out into the valley. ? Moraines are long ridges of glacial till. Terminal moraines are long ridges of debris deposited at the end (toe) of the glaciers. Lateral moraines form along the sides, parallel to the glacial valleys.
