Cirque. A cirque (French: [siʁk]; from the Latin word circus) is an amphitheatre -like valley formed by glacial erosion. Alternative names for this landform are corrie (from Scottish Gaelic: coire, meaning a pot or cauldron) [1] and cwm (Welsh for 'valley'; pronounced [kʊm]). A cirque may also be a similarly shaped landform arising from ...
Pyramidal peak. The Matterhorn, a classic example of a pyramidal peak. A pyramidal peak, sometimes called a glacial horn in extreme cases, is an angular, sharply pointed mountain peak which results from the cirque erosion due to multiple glaciers diverging from a central point. Pyramidal peaks are often examples of nunataks.
Erosional landforms. As the glaciers expand, due to their accumulating weight of snow and ice they crush, abrade, and scour surfaces such as rocks and bedrock.The resulting erosional landforms include striations, cirques, glacial horns, arêtes, trim lines, U-shaped valleys, roches moutonnées, overdeepenings and hanging valleys.
Cirque glacier. A cirque glacier is formed in a cirque, a bowl-shaped depression on the side of or near mountains. Snow and ice accumulation in corries often occurs as the result of avalanching from higher surrounding slopes. If a cirque glacier advances far enough, it may become a valley glacier. Additionally, if a valley glacier retreats ...
Cirques are where ice begins to accumulate in a glacier. Two glacial cirques may form back to back and erode their backwalls until only a narrow ridge, called an arête is left. This structure may result in a mountain pass. If multiple cirques encircle a single mountain, they create pointed pyramidal peaks; particularly steep examples are ...
The Cirque de Gavarnie (French pronunciation: [siʁk də ɡavaʁni]) is a cirque in the central Pyrenees, in Southwestern France, close to the border of Spain. It is within the commune of Gavarnie, the department of Hautes-Pyrénées, and the Pyrénées National Park. Major features of the cirque are La Brèche de Roland (English: Roland's Pass ...
Glacial cirques (or 'corries') form as hollows on mountainsides near the firn line. Eventually, the hollow in which a cirque glacier develops may become a large bowl shape in the side of the mountain, caused by weathering, by ice segregation, and as well as being eroded by plucking. The basin will become deeper as it continues to be eroded by ...
Cirque du Soleil (French: [siʁk dy sɔlɛj], Canadian French: [sɪʁk d͡zy sɔlɛj]; "Circus of the Sun" or "Sun Circus") is a Canadian entertainment company and the largest contemporary circus producer in the world. [7] Located in the inner-city area of Saint-Michel, Montreal, it was founded in Baie-Saint-Paul on 16 June 1984 by former ...
