Roche moutonnee geology jokes
The passage of glacier ice over underlying bedrock often results in asymmetric erosional forms as a result of abrasion on the "stoss" upstream side of the rock and plucking on the "lee" downstream side. When the glaciers retreat, they leave behind a distinctive landscape of stark erosion mixed with deposits of dense, unsorted till. Sorry, this content is being updated. Contents Coastal areas are subject to change on a daily basis. They also look at the ways in which human activity has altered the coast and continues to influence the development of coastal landforms.

Some material is relevant to more advanced students and those GCSE candidates seeking a greater understanding of coastal processes. Image credit: John Shaw. Where a seismic survey had nothing anomalous, a seismic survey picked up the reflection of a 10 meter high, meter wide lump that may be a proto-drumlin growing under the ice.

All that changed when researchers in Iceland accidentally spotted the world's only active drumlin field while out on an entirely unrelated glaciological field expedition.

A better understanding of how drumlins form could lead to better reconstructions of the glaciological history of the region. Jezebel The Slot. A more recent theory for erosion is outlined in a truly delightful and metacognitive paper by John Shaw, explaining how meltwater and outwash from the glacier could carve under-ice material, leaving behind drumlins as slightly-more-resistant nubs under the ice.
If drumlin formation is related to rapid surges forward by glaciers, they could also give us greater insight into the speed of ice flow along with the existing hints of directionality. These pages look at the causes of earthquakes and tsunami, how they are detected and measured, and the ways in which they might be predicted.

Image credit: Johnson et al. Idealized sketch illustrating the potentially diverse internal structure of a drumlin, and the deceptive impression formed by limited natural exposures 1,2,3. The internal composition of a drumlin varies from stratified sand to unstratified till to solid bedrock, with every possible permutation between. The depositional theory is that some slight change in pressure from the ice above or variation in the material below results in increased deposition. Drumlin fields are usually near with the terminal moraine that marked the farthest edge of a glacier, associating them as a feature created by ice dynamics at the outer edge of a glacier or ice sheet. The main problem is that drumlins are formed under the ice, so we can't actually see what's happening in sufficient detail. Almost every drumlin we study is from at least several thousand years ago, created during the last ice age when vast continental ice sheets crept across the land. |

The exact details of the hypotheses have changed over time, but the basic ideas remain the same. When glaciers creep over a landscape, they scour it clean of loose material, strip it of vegetation, polish the very bedrock, then rebury it all in thick layers of jumbled rock and sediment. Helens Case Study.
They are also home to very distinct features and processes. Part of the mystery lays in their extreme variability in composition: drumlins can be made of carved bedrock, the chaotic jumble of glacial till, the tidy sorted muck of glaciofluvial sediments, or some desperately confusing mixture of all three.
