Understanding Glacial Features: Erosional Landforms and Formation Process

Glacial Landform Formation and Processes - A comprehensive guide exploring the formation of major erosional landforms of glacier and their development processes.

Types of glaciers in Geography play a crucial role in shaping mountain landscapes through erosion processes including abrasion, freeze-thaw, and plucking
The formation of key features like arêtes, corries, U-shaped valleys, ribbon lochs, and hanging valleys demonstrates the powerful erosive capabilities of glaciers
These glacial landforms examples are primarily formed in North and Northeast-facing locations due to favorable conditions for snow accumulation
The process involves the transformation of snow into neve ice and eventually glaciers, which then shape the landscape through various erosional mechanisms

Page 2: Corrie Formation and Pyramidal Peaks

This page expands on corrie formation and introduces pyramidal peak formation process. It explains how corries develop their characteristic armchair shape and the formation of bergschrund crevasses.

Definition: A bergschrund is a crevasse that forms where the moving glacier pulls away from the mountain's back wall.

Example: Red Tarn is cited as an example of a corrie.

Highlight: Pyramidal peaks form when three or more corries develop back-to-back, creating a pointed summit.

Example: Stob Ban in Fort William is given as an example of a pyramidal peak.

Page 3: U-Shaped Valley Formation

The page focuses on how V-shaped river valleys are transformed into U-shaped valleys through glacial erosion.

Definition: A U-shaped valley is a glacially eroded valley with steep sides and a flat bottom.

Vocabulary: Misfit stream - The original river that appears too small for the valley it occupies after glaciation.

Example: Glen Nevis is provided as an example of a U-shaped valley.

Highlight: The process involves the elimination of interlocking spurs and the widening of the valley floor.

Page 4: Ribbon Loch Formation

This page begins to explain the formation of ribbon lochs, another significant glacial landform. The text emphasizes the importance of north and northeast-facing valleys in the formation process.

Highlight: The formation process follows similar patterns of erosion as other glacial features, involving abrasion, freeze-thaw, and plucking.

Vocabulary: Ribbon loch - A long, narrow lake formed by glacial erosion.

Ribbon Loch Formation

Ribbon lochs represent distinctive glacial landforms examples created through differential erosion patterns.

Definition: A ribbon loch is a long, narrow lake formed when glaciers erode deeper into areas of softer rock within a U-shaped valley.

Highlight: The formation process involves selective erosion where glaciers excavate deeper channels in areas of weaker rock.

Page 1: Formation of Arêtes and Corries

The page details the formation processes of two major glacial landforms: arêtes and corries. The process begins with snow accumulation in north and northeast-facing hollows, where shade preserves the snow cover.

Definition: An arête is a sharp, knife-edge ridge formed when two corries develop back-to-back on a mountain.

Vocabulary: Neve ice - Compressed snow that forms through the weight of accumulated snowfall.

Example: Striding Ridge is provided as a real-world example of an arête.

Highlight: Three main types of glacial erosion are introduced:

Abrasion: Rock fragments in ice act like sandpaper
Freeze-thaw: Water freezing and expanding in rock cracks
Plucking: Glacier freezing to and pulling away rock
