Cirques (alternatively known as Corries in Scotland and Cwm's in Wales) are masses of ice that carve out an arm-chair shaped hollow with a steep back wall and a steep headwall. Snow fall collects in the already evident (if not small) hollow on the mountain side. They are prevalent on north facing slopes as they recieve less sunlight so accumulation exceeds ablation. A series of processes collectively known as Nivation (processes that occur under and near a snow patch) including freeze-thaw, solifluction, erosion, weathering etc. These processes cause the underlying rocks to disintegrate, and the hollow deepens. As the snow patch grows, its layers become increasingly compressed to form firn and eventually ice. Plucking steepens and scours the sidewalls and headwall, as the material is removed from the valley sides. A rotational movement of ice flow enables abrasion to deepen the hollow further. Cirques often form valley glaciers as they fill up the hollow and spill over the rock lip.
A cirque is a glacial landform that resembles an armchair. It is a bowl-shaped hollow with steep sides formed at the head of a glacier where ice erosion and plucking have occurred.
What can happen when the glacier melts in a cirque
Emmons Glacier is the largest glacier on Mount Rainier and is located within a cirque, which is a bowl-shaped hollow at the head of a valley. This cirque, known as Emmons Cirque, was carved out by glacial activity over thousands of years.
Cirques. They are the bowl-shaped depressions formed by the erosion of glaciers in the upper parts of alpine valleys.
A cirque glacier is a small glacier that occupies a cirque or rests against the headwall of a cirque. A cirque is a deep, horseshoe-shaped hollow with steep walls which was created by erosive activity of glaciers.
A Cirque
A cirque, also known as a Cwm or Corrie, is a feature of glacial erosion, formed in a mountainside.
A cirque is a glacial landform that resembles an armchair. It is a bowl-shaped hollow with steep sides formed at the head of a glacier where ice erosion and plucking have occurred.
A tarn (or corrie loch) is a mountain lake or pool, formed in a cirque excavated by a glacier.

A ' Tarn' is a mountain lake or pool formed in a cirque excavated by a glacier.

No, wind erosion does not cause a cirque. A cirque is a bowl-shaped depression formed by glacial erosion, typically found on the side of a mountain. Wind erosion is the process by which wind moves and erodes materials like sand or soil over time.

A deep and steep bowl-like depression produced by glacier erosion is called a cirque. The word "cirque" is a French word for "arena". A cirque is also known as a corrie.
Cirque as in Cirque de solei
A glacial cirque is formed when a glacier erodes the headwall of a valley through processes like plucking and abrasion. As the glacier moves downhill, it creates a bowl-shaped depression with steep walls. After the glacier retreats, the cirque may fill with water, forming a tarn or glacial lake.
