Yr12 Cold Environments

Whilst I was off, you were researching and putting together a timeline and an annotated map showing the human activity in Antarctica. I now have that work from most of you, but there are still a few who didn't manage to find their way to the Humanities Block before the end of schoool today, and I am not very happy about that.

You also should have spent some time checking that you had thorough notes about each of the glacial landforms we mentioned (U-shaped valleys/glacial troughs, ribbon lakes, corries, aretes, pyramidal peaks, roche moutonnees and drumlins).

Yesterday, we looked at fluvioglaciation - processes and landforms caused by glacial meltwater. The photos we looked at at the start of the lesson were of Skeidarasandur - lots more on Flickr and it is worth a quick search to find out a bit more about the jokulhlaups that we mentioned.

For Tuesday next week (to Mrs Chambers), I asked you to describe and explain the landforms that you would expect to find in a fluvioglacial landscape. (You should be including outwash plains, braided streams, eskers and beaded eskers, kames and kame terraces, kettle holes, diverted drainage and proglacial lakes.)
