我碰到不清楚的解释当试图思考情况冰盖是推进和出现悬崖。* *接下来会发生什么?冰盖如何越过悬崖?基本困吗?* *创建一些地貌到原始的悬崖吗?的强制应用应该很强(或许将继续适用于很长时间)。同时,冰川的流动是如何在这些位置发生吗?悬崖会暴露于液态水流动在整个时期冰盖覆盖它,这不会导致快速侵蚀cliff-surface ?- - - - - - - - - - -从地质的角度来看,这是发生在[波罗的海克林特·][1]尽管大多数这些悬崖在15 - 25米的范围,换句话说,相对较小的冰原。然而,也有一些暴露(目前的水上)部分略高。 I've put a small map (20m DEM; generally one front of cliffs by the modern coastline and then occasional ones further inland) below which illustrates where this would have been happening during the last glaciation period based on the example of Tallinn, Estonia, though by no means is this the only place where such a situation would have occurred. [![enter image description here][2]][2] Of course, the DEM has further problems, including that ~20k years of isostatic uplift has raised these a fair bit since so the actual obstacle that the ice sheets met should have been smaller (perhaps was: are the remnant limestone mounds the part that didn't get washed away?). I also find the sentence (from the above Wikipedia page) weird: > However it is not known to which degree the Baltic Klint originated in postglacial time or if it evolved from cliff-like forms sculpted by the Fennoscandian Ice Sheet. In Gotland 20th century cliff retreat rates have been estimated at 0.15 to 0.78 cm/year. I don't see how the ice sheet's advance/retreat could have caused such a cliff if the limestone plateau did not exist there beforehand. ---------- I'm not expecting an answer based on this location specifically, but rather perhaps there are some imaged cliff-faces in Greenland/Antarctica where this behaviour has been recorded presently? I tried some searches and found [this][3] which seems relevant but I wasn't able to access the full text.

\ begingroup美元似乎很明显,冰川将来到悬崖脚下,堆积,直到它突破它,然后上面的冰崖就会继续。还是我遗漏了什么东西? \ endgroup美元

\ begingroup美元 @gktscrk:我只是猜测,但我认为冰川的飞机顶部的悬崖。毕竟,冰川是相当强大的eroders景观,e。约塞米蒂山谷,无数fijords,五指湖区,明目的功效。 \ endgroup美元

\ begingroup美元我想,您需要指定一些东西。你感兴趣的一个典型的高山冰川的行为,或者说,冰河时期冰盖?也,你有兴趣冰川“表现”,或如何创建这样的功能呢? \ endgroup美元
