Glacial Landforms...

Some interesting mini-lessons this morning!

We took rather a long time to work our way through the glaciation "dominoes" - we'll have another go tomorrow and see if we can be a bit speedier!

We then had a look at various glacial erosional landforms (glacial troughs; truncated spurs; corries; aretes; pyramidal peaks; ribbon lakes; hanging valleys...) and glacial depositional landforms (moraines - terminal, lateral, medial, recessional; roches moutonnees; drumlins...) and how they are formed. We still need to have a look at fluvioglacial and periglacial landforms.

Some pictures for you.... what features can you spot? And where were the pictures taken?

Last week...

On Wednesday, we had a look at the anagrams (which, as usual, were not mistake-free, but have now been corrected - I hope!).

We talked about the fact that rivers have ENERGY, and as a result of variations in energy, they can ERODE, TRANSPORT and DEPOSIT material.

Processes of erosion:
- attrition
- abrasion (corrasion)
- hydraulic power/action
- corrosion

We also mentioned VERTICAL, LATERAL and HEADWARD erosion.

Processes of transportation:
- solution
- suspension
- saltation
- traction

We then had a look at the Hjulstrom Curve - some nice bits about that here (don't forget to click Next Page and have a look at all the info on there).

Don't forget about COMPETENCE and CAPACITY as well, when you are thinking about a river's load.

And a nice game of Sink or Swim (thanks to Alan P of GeographyPages, GeographyJazz, Cultcha, etc. fame for the idea!)
