Freeze-thaw erosion appears to be missing from this article.

Erosion is not really ye field so I'd prefer someone more knowledgeable to add freeze-thaw erosion to this article. For example doi: 10.13287/j.1001-9332.201901.019. entitled "Research progress on the effects of freeze-thaw on soil physical and chemical properties and wind and water erosion" says in it's abstract "Freeze-thaw erosion, one of the main types of soil erosion, is widely distributed in China.". Even a mention of it would be good. I was gong to reference the erosion article from another I am assembling on freeze-fracture but it won't make sense to reference the erosion article if there is no reference to freeze thaw erosion. If I don't hear back from anyone soon I will presume no-one is currently editing the erosion article and may then add a sentence or two myself if no-one objects. Thanks.

Freeze-thaw is probably absent from this article about erosion because it has been included in the weathering and frost weathering articles instead (weathering being the in situ decomposition of rocky material, erosion being the subsequent movement/removal of the weathered material). By the way, freeze-thaw is also not included in the more detailed soil erosion article. This might be a language/terminology problem, with people incorrectly assuming that weathering and erosion are synonyms in English. A search for "freeze-thaw erosion" in academic journals via Google Scholar gives only 882 hits, almost all of them by a small group of Chinese scientists.

Pirunpesa

It's not immediately clear what the Pirunpesa image is doing in the glaciers section. The (confusing) article on this feature makes greater reference to glacial deposition (hole filled with glacially transported materials) than erosion. In the absence of clear information, I'm assuming it may have been formed not by ice per se, but by glacial meltwater - perhaps subglacially? cheers Geopersona (talk) 07:36, 8 December 2024 (UTC)[reply]

Misrepresented images?

The photo captioned Layers of chalk exposed by a river eroding through them appears to show a hard limestone rather than chalk, specifically. The one below is captioned Green land erosion - what does that mean? Geopersona (talk) 07:20, 1 January 2025 (UTC)[reply]

Chemical erosion (again)

This topic was brought up here - I'm unclear what is meant by 'chemical erosion' as opposed to 'chemical weathering' -the latter being most commonly experienced in relation to the disintegration of carbonate rocks. The dissolved material is removed from the immediate site by water flow - is that really to be characterised as 'chemical erosion'?
