Yr12 Cold Environments

Periglaciation this week - discussion of what "periglacial" means, climate of periglacial areas (and a climate graph for Svalbard, which I should have from all of you by now), permafrost, periglacial processes (freezing/thawing of permafrost, frost-heave, nivation, freeze-thaw weathering). On Monday, we'll have a look at periglacial landforms.

As ever, click on the tags at the bottom of the post to link to previous posts about periglaciation, links, etc.

Year 13 - Periglaciation... And a test...

Check back to the previous periglaciation post for links to a number of sites about periglacial environments and landforms...

This National Geographic article looks at permafrost and has some great images such as this one:

Some of you didn't do quite so badly as you thought in the test that followed... However, it was a reminder of the importance of revising as you go along and really making sure that you learn key terms - make yourself some cards with key terms and definitions on them and play snap... Or stick post-it notes around your room (or the whole house!)...

Periglacial Landforms

Research yesterday into the main landforms and features that you are likely to find in a periglacial region...

Some sites that might be useful:

Although you might well find a selection of other strange things as well, searching Flickr for the names of the various landforms and features will likely produce some good photographs to give you a clearer idea of what the features look like. Although I've just searched it for "pingo" and not found anything, the Geography Teachers' Resources Group on Flickr that I mentioned might be useful as well.
