Aug 9, 2024 · Learn about the formation of glacial landforms from corries to troughs, along with examiner tips and worked examples for the AQA GCSE Geography exam.
The formation of a glacial trough involves two processes abrasion and plucking. Abrasion is when pieces of debris in the glacier wear away at the rocks below, a bit like sandpaper. The...

These are valleys formed by the glacial processes of weathering, erosion and transportation. They have steep sides and flat floors. Unlike V-shaped river valleys, glacial troughs are straight as they have truncated any interlocking spurs which existed prior to glacial advance.
Glacial troughs. Rivers cut V-shaped valleys through the process of erosion. As rivers in their upper course don’t have that much power, they are forced to wind between harder rock leaving ridges...
