Cirques are formed because of influences from both erosion and glaciers. It forms mainly on covered hills which do not see a lot of sunlight, which allows snow to fill up the area. This snow will freeze and melt inside the surface, creating a tearing effect, creating a cupped section in the earth.

Cirques are formed by glaciers eroding rock and sediment in a circular basin in a mountainous region. As the glacier moves and excavates the basin, it deepens and widens the depression to create a steep-sided amphitheater-like feature known as a cirque. These formations are a common feature in glaciated landscapes.

What helps form cirques and U-shape valleys?

Cirques and U-shaped valleys are formed by glacial erosion. Cirques are formed by the erosive action of a glacier in a bowl-shaped depression at the head of a valley. U-shaped valleys are carved out by glaciers as they flow down a mountain, eroding the surrounding rock and creating a distinctive U-shape.


Are cirques formed by erosion or deposition?

Cirques are typically formed by erosion. These bowl-shaped depressions in the landscape are carved out by glaciers over time, as they move downhill and erode the surrounding rock through processes like freeze-thaw weathering and abrasion.


Bowl-shaped depressions or hollows found near mountain peaks?

These are likely cirques, which are bowl-shaped depressions formed by glacial erosion near mountain peaks. Glaciers carve out cirques through a combination of plucking and abrasion, creating distinctive features in mountainous regions.
