CIRQUE
Sharp pyramid-shaped peaks formed by alpine glaciers are called "horns." These features occur when multiple glaciers erode a mountain from different sides, creating steep, pointed summits. The most famous example is the Matterhorn in the Swiss Alps. Horns are typically characterized by their rugged, jagged profiles, resulting from the intense glacial activity.
Glacier landscapes are characterized by U-shaped valleys, rugged terrain, and sharp peaks due to the slow movement and erosion of ice. Landscapes formed by water, such as rivers and streams, typically have V-shaped valleys, gentle slopes, and rounded features due to the faster flow of water and erosion. Glaciers tend to create more rugged and angular landscapes compared to water.
V-valley refers to a type of valley on a topographic map that has a V-shaped profile, typically formed by erosion from a river or stream. U-valley refers to a valley with a U-shaped profile, typically formed by glacial erosion. V-valleys are more narrow and have steeper sides compared to U-valleys.
Upper Teesdale, located in the north of England, was formed by the action of glaciers during the last Ice Age. The movement of these glaciers over millions of years carved out the landscape and shaped the valley. The Tees River further sculpted the area, creating the unique features seen in Upper Teesdale today.
A U-shaped valley is most likely formed by the process of deposition from glaciers. Glaciers carve out valleys as they flow, leaving behind sediment and debris when they melt. This material can accumulate at the base of the glacier, creating a U-shaped valley.

A cirque is a surface feature formed by glaciers that is shaped like an armchair. It is a large bowl-like depression with steep walls carved out by the glacier's erosion.
Armchair-shaped valleys are U-shaped valleys that have a distinctive shape resembling an armchair. They are formed by glaciers eroding the landscape, creating steep side walls and a broad, flat bottom. These valleys are often found in mountainous regions where glaciers once existed.
Armchair-shaped valleys are also known as U-shaped valleys. These valleys are typically wider and have steep, straight sides with a flat bottom. They are formed by glaciers as they move through a landscape, carving out the valley into its distinctive shape.
Land features formed from ice erosion include cirques, u-shaped valleys, and fjords. Cirques are bowl-shaped depressions at the head of a glacier, u-shaped valleys are deep valleys with steep sides carved out by glaciers, and fjords are long, narrow inlets with steep cliffs created by glaciers flowing into the sea.
Yosemite Valley and Lake Tahoe were formed as a result of erosion by glaciers in California. Yosemite Valley was carved by glaciers over millions of years, creating its iconic steep walls and U-shape. Lake Tahoe was also shaped by glaciers during the Ice Age, carving out its basin and surrounding peaks.
Sharp pyramid-shaped peaks formed by alpine glaciers are called horn glaciers. Horn glaciers are created when three or more cirque glaciers erode a mountain from different sides, leaving behind a sharp-edged peak. Famous examples include the Matterhorn in the Alps.

Glaciers can form various landscape features, including U-shaped valleys, cirques, aretes, and moraines. These features are created as glaciers erode and deposit material as they flow over the land.
Glaciers form U-shaped valleys. They make striations, drumlins, kettlelakes, eratics, moraines and cirque.
