Geography - Isostasy

joema

Im learning rivers in detail. I already know the processes of transportation and erosion aswell as two landforms.

But for isostasy should I know two landforms and 2 case studies of how isostasy can be seen in the Irish landscape today aswell?

I know the case studies - 1) Rivers of Donegal and 2)Peneplain in Munster

I dont know why you learnt those case studies.
I got an A1 in Geography in the mocks its the easiest subject ever. Cut down your learning big time so youll remember the important stuff!

For the Physical geography question using rivers:

Learn 2 landforms with the processes that formed em:
1. Waterfall - landform of erosion
2. Meanders - landform of erosion and deposition

Part C is either to do with isotasy or human interference with rivers.
Learn:
What isotasy is all about
When the last one happened
2 landforms caused by it ie. Raised beaches,incised meanders,paired terraces,knickpoints.

For human interference take the aswan dam and talk about how the dam stops it transporting its load, causes erosion downstream, causes deposition.

this is gona sound weird but.... whts isostasy??????

I've absolutely no idea either. I've gotten a few handouts from my teacher on it because I was out. So I'll have to learn them during the week.

Have a look through your book it should in there or the LSMS book.

Will we get a choice between doing a question from chapters 1-5 and one on rivers?? Or are they always combined...?? Trying my best to leave stuff out here lol.

Funkstard

I think the physical questions are 1:tectonics/volcanoes 2:rocks 3: processes.

Take from that what you will. I haven't touched rocks and don't plan on doing so.

EDIT: Stupid bastard smilies

ThrownAway

So hmmmm ...I might be able to leave out processes

.... It's very risky though

Learn chapters 1-5 well and block out everything to do with rivers/glaciers/sea and whatever

Funkstard

yep. you can

IbanezFreak

Isotasy came up on the sample paper so it has a good chance of coming up for the real thing. Its either that or human interference with surface preocesses.

Definition: Isotasy is the vertical movements of the earths crust.
(Think of it as the opposite to plate techtonics which is horizontal movements of plates)

When weight is put on the crust it falls (Isostatic fall)
When weight is taken from the crust it rises (Isostatic Rise)

The last time there was isostatic movements was at the last ice age.
Vast amounts of ice were stored on land.
This caused:
1. Sea levels to fall (Water was stored on land)
2. Crust levels to fall (The weight of the ice pushed it down)

When the ice age finished the glaciers melted and massive volumes of water flowed into the sea.
This caused:
1. Sea Levels to Rise (Water flowed into sea)
2. Land levels to Rise (Weight was released)

There is much evidence to prove isostatic movements affected Ireland in the past.
Explain two w/ diagrams:
1. Knickpoint
2. Raised Terraces
3. Incised Meanders
4. Rasied Beaches/Caves

I recommend you learn a knickpoint and a raised cave.

IbanezFreak

Oh yeah n if people arent doing the Rivers question I recommend you do the rock cycle.

Simply learn learn all the rock types.
Then learn one type in detail (Limestone),How it was formed and how it can produce such a distinctive landscape *Karst region ie. The burren
And then just learn about quarrying to show how humans interact with the rock cycle. The less stress more sucess book has a good page about how humans interact with the rock cycle.

Remember only focus on one topic. If you ****e with OS Maps (Like myslef!) consider doing the rock cycle.

joema

Im doing rivers in detail, is that all I need to know to be covered for q1 to 3?

Funkstard

If you can give a good answer for human interaction with rivers, have two surface processed covered you should be alright.

Is anyone else doing plate tectonics? Is all the folding and stuff in that or is it in rocks? If it is in tectonics I've just wasted a full day's studying

I wrote about a page on this as a sample answer last week, I can type it up if ya want, but nothing to fancy, it will tie you over if you get it in the exam though

"Explain how the effects of isostatic processes can be seen in the irish landscape today"

Rockerette

to me, physical geography is physical geography, you guys are fascinating with all your sub categories tho!

maybe i should be worried?!


volcanos.. earthquakes.. a bit on glaciers.. bit on rivers.. rocks.. plate movements..

for me, its just "the physical section"..


and as for isostasy, never even heard the word before.. hehe i suck

U need to have a very basic understanding of them for the short answer questions but if you cant talk about one section in detail your throwing away marks. Geography is one of those subjects that you learn it, reproduce it and get the marks. The stuff on rivers which i sed above is all ya gta know. Its only a tiny bit of info really, its just picking it out of the geography book thats the hard thing. If ya havnt prepared for it dont waste your time studying english poets r anything because youll easily pick up easy marks in this section for about max 5 hours study.

Does anybody know a site where I can find out about this Aswan stuff? bbc.co.uk has nothing, unfortunately.

Many thanks in advance.

For human interference i prefer the Bull wall, built at a right angle to the coastline at Dublin Bay. Built to protect port from Longshore Drift, intereferes with Erosion as the water cannot reach the coastline with as much momentum (hydraulic action). Interferes with Deposition as sediments are deposited at the wall instead of in the bay.

As a result of this Interference, the port is now able to have larger ships in it.


Plenty of Srps there, and able to expand on them further too.

Easy diagram to draw for another Srp aswell.

:P

Rockerette

hehe lads you'll be delighted to know i opened up my geog book.. and found the chapter on this crazy isostasy stuff you're talking about...!

i swear i had never seen the pages before ever.. hhmmm..


it just kinda looked like physics a bit to me!


but yeah.. might take a look, thank ye guys for waking me up a bit.....

Just in case ppl dont realise thats for a costal topic. I dont think you can mix them. Actually maybe you can?!

you can, that's the brilliance of the new course!!

I'm not sure what I'm going to study though I'm trying to avoid rivers and landforms and just do chapters 1-5.

BUT...

On sample paper two there's a question 2 B ...

''Examine how volcanic activity gives rise to two distinctive landforms.'' [30]

Is that something to do with river landforms??
What the hell are volcanic landforms? Are they even in the book?

I just found another one on sample paper 3

''Examine the formation of two landforms which result from volcanic processes'' [30]

When they say the FORMATION do you just write the formation and nothing else??

So you can do your question B on two river landforms and then do the sea for human activity in part C?

NADA

There is probably going to be a question on rivers rocks and tectonics. I know all three. I hope!

ThrownAway

What like all in one question

Funkstard

I presume two landforms would be the actual volcanoes themselves and a volcanic island?

yes, i asked my teacher about this today

you take A, B and C as separate questions..

No you can't, you answer 1 full question, not bits one of one and part of another

Yep.^^^

Funkstard

Does everyone know what they're studying for the regions? I just finished the Mezzogiorno there and covered the problems facing agriculture, development of the region (cassa per il mezz.) and tourism. Should cover any question they could ask on a peripheral european region right?

Regions Ive' done are Ireland (west, north east) Scania (core) in sweeden
Peripheral (andalucia spain) Region in industrial decline Basque county?-(northern spain) And Uganda, and india too. Mainly covering either agriculture, industry etc... I did a ton of sample answers over the year, So I can just read over them

ThrownAway

I think Lauren Some Apparel was trying to say that you can answer your question B on Rivers and then your C on the sea if they were both asked in the SAME question.

Funkstard wrote:

India [did anyone else have to learn about the economic challenge of the religious divide? BOOORING]
Mezzigiorno
Scania
West and East of Ireland

Haven't time for anything else.

Funkstard

Well I'm doing East/West Ireland, Paris Basin, Mezz. & India. More than enough methinks. There was no question on a region in industrial decline on the sample paper...I didn't even know we had to study one. We did one for the economic elective, but not for regional. I'm sure these words will come back and kick me in the bollix now, but oh well.

i meant

question 1 A
is not directly linked to 1B
which is not directly linked to 1C

you take each part as a separate question...

but answer ABC from the same number.

and to another question, yes we have informal school during the House exams for the rest of the College, we can pick and choose classes.
quite handy really

helles belles

ive given up on geo!
its taking to much time to study and i only took the subject up this year (im repeating).
im doing 7 honours so im just going to turn up for the exam, but im putting no more work into it.

isobeltowse

how do you start a new thread.
i wanna know if i can get away with learning one surface process landform or do i have to learn one of each, erosion, deposition, transp...
