Neck cutoff channels are commonly formed the same way when an overbank flow occurs during a flood and the narrow piece of land between a bend in a meander is eroded away; this is known as rush-cutting. [5] A meander can also be cutoff by a channel due to excess sediment upstream as a result of high erosion
Epigenetic valley – Valley created by erosion and with little or no sympathy for bedrock structure; Esker – Long, winding ridge of stratified sand and gravel associated with former glaciers; Exhumed river channel – Ridge of sandstone that remains when the softer flood plain mudstone is eroded away
A] By some estimates the Quaternary glaciers eroded away on average 25 m of rock in Finland, [2] with the degree of erosion being highly variable. [5] Some of the material eroded in Finland has ended up in Germany, Poland, Russia and the Baltic states. [2] Ground till left by the Quaternary ice sheets is ubiquitous in Finland. [2]
This would resist erosion while the surrounding surface is eroded away to create a ridge. Cementation of underlying sediments by minerals dissolved in water may occur in a depression. On Earth, this often happens in stream valleys as the result of the formation of duricrusts, i.e., silcrete or ferricrete, by pedogenesis. Minerals for ...
2. A heavily eroded area along a river featuring steep banks, bluffs, ravines, or gorges. The term is used chiefly in the plural (i.e. breaks) and primarily in the United States and Canada. breaker 1. Another name for a breaking wave. 2. A reef, shoal, bar, skerry, or area of shallow water against which waves routinely break. breaker zone
Weathering and erosion prevailed, and the mountains began to wear away. [18] By the end of the Mesozoic Era, the Appalachian-Ouachita Mountains had been eroded to an almost flat plain. Sediments eroded from these highlands were carried east and southward by streams and gradually covered the faulted continental margin, burying it under a wedge ...

Protracted erosion also means most of the Paleogene and Neogene sediments have been eroded away or, as known in a few cases, buried by Quaternary deposits. [15] Before the Quaternary glaciations affected Ireland the landscape had developed thick weathered regolith on the uplands and karst in the lowlands. [ 14 ]
