May 28, 2023 · Troughs are marked with a black dashed line, and ridges with a white zig-zag line. However, this flow is unstable, allowing small disturbances (e.g., flow over mountain ranges) to grow into large north-south meanders (Fig. 11.49b) of the jet stream.
Unlike V-shaped river valleys, glacial troughs are straight as they have truncated any interlocking spurs which existed prior to glacial advance. These are valleys formed by the glacial processes of weathering, erosion and transportation.
Learn about and revise glacial landforms and processes, including weathering, erosion, transportation and deposition, with GCSE Bitesize Geography (AQA).
Oct 3, 2024 · Characteristics of Glacial Landscapes. The glacial system are the processes of erosion, deposition and flow of material (ice, water and debris) across the Earth's surface. These processes produce erosional and depositional features, that overall, produce the glacial landscape.

How do meteorologists find troughs?
Glacial troughs and fjords are deep erosional features calved into bedrock marking glacial activity [1,2]. The most characteristic difference between a trough and a fjord, is that a fjord ends in a coastal region, and is flooded by sea water [3].
