Sumário
Corries form in hollows where snow can accumulate. A neve se compacta em gelo e isso se acumula ao longo de muitos anos para compactar e crescer em uma geleira corrie/cirque. Isso então se move morro abaixo por causa da gravidade e da massa do gelo.
What do corries look like? A corrie is an armchair shaped hollow high on a mountain with steep back and side walls. Snow gathers in mountain hollows , especially north facing hollows, where there is more shade.
also, What are the 3 stages of a corrie? Corrie features

Is a corrie a valley? Corrie (Also called cirque) – Armchair-shaped hollow in the mountainside formed by glacial erosion, rotational slip and freeze-thaw weathering. This is where the geleira do vale começa. Quando o gelo derrete, pode deixar um pequeno lago circular chamado tarn.
Why are ribbon lakes called ribbon lakes?
À medida que uma geleira flui sobre a terra, ela flui sobre rochas duras e rochas mais macias. Rochas mais macias são menos resistentes, então uma geleira irá esculpir uma depressão mais profunda. Quando a geleira recuar, a água (derretida) se acumulará na área mais profunda e criará um lago longo e fino chamado lago de fita.
What is the difference between bergschrund and crevasse? A crevasse is a deep, wedge-shaped opening in a moving mass of ice called a glacier. … Bergschrunds are cracks that appear between the moving ice of a glacier and the non-moving, or stagnant, ice of a mountain or cliff.

Alternatively, drumlins may be residual, with the landforms resulting from erosion of material between the landforms.
What is glacial horn? 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.
