   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 sharper...

   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.

   Jan 1, 2014 · The glacial trough is also called “U” shaped valley, relatively straight, flat-bottomed, deeper, and steep-sided valley formed by glacial erosion (Figure 1). Originally the valley would have in existence as stream/river valley prior to occupation by a glacier.

   May 28, 2023 · The equatorward region of any meander is called a trough (pronounced like “troff”) and is associated with low pressure or low geopotential height. The poleward portion of a meander is called a ridge, and has high pressure or height.

   What is a glacial trough or U shaped valley?

   • Below us you can see the Great Langdale valley. This is what geographers call a glacial trough or U shaped valley. Would you like to explain? Tourist: During the glacial period, this valley would have been filled by a glacier, which is a bit like a huge river of ice.

   What can you find in a glacial trough?

   • • Within a glacial trough you can also find hanging valleys and waterfalls, truncated spurs, misfit streams, ribbon lakes, rock steps and basins. • The main processes involved in the formation of glacial troughs are abrasion and plucking.

   What does a trough look like?

   • 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. These meanders are called Rossby waves or planetary waves. Typical wavelengths are 3 - 4 Mm.

   How do meteorologists find troughs?

   • The largest vorticities are concentrated near the wave crest and trough, allowing meteorologists to use positive vorticity to help find troughs. Figure 11.a. Jet-stream path (blue) and associated vorticity (thick red).
