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?

Today...

Some very good mini-lessons today - well done.

We looked at rias, fjords, raised beaches and relict cliffs. We talked about eustatic and isostatic sea level change (we will talk about this more at a later date).

We also looked at geos, blowholes, cracks, caves, arches, stacks, stumps, headlands and bays, wave-cut notches and wave-cut platforms. We also considered concordant and discordant coastlines.

Make sure that you are clear about all of these!

The revision website that Laura mentioned is www.revision-notes.co.uk - there is some useful stuff on there but I've just spotted several mistakes in the bits I've looked at so be careful!! The S-Cool site that I have mentioned before is also handy.

If you are in the group that were not ready today, make sure that you are sorted for Friday (I will definitely be in school, and so there will definitely be a lesson).

Also, a reminder about Wales money/permission slips... Someone asked if you can pay all the money at once - absolutely you can if you/parents are happy to do that!! The sooner it's sorted the better!

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!)
