Re: Edexcel Geography Unit 4 Tectonic activity & Hazards (2016)

Hi, The east African Rift Valley is at a constructive plate boundary and the landscapes that are created are normal faults (from seismic extension) and then the fault scarp/horst/graben that come along with faulting. There tends to be some volcanic activity where the plates are splitting but you don't need to mention that. Then, sometimes if the rift valley is near a sea (EAR is) It can become an oceanic rift valley when the sea floods in.

This was useful for me too because it helps me sum it up in my head!
Hope that helps

I can send you a draft I have written if that would help you with structure case studies etc ...

Does anyone know if we need to describe the plate boundaries at all in the methodology/introduction?

I have drawn diagrams in my intro of the plate boundaries and the things that happen at each one. I.e the features, type of lava etc.

How many case studies are you using? and how are you going to fit them all in to time

Got a case study for each feature. But I don't think I will have enough time

Asked my teacher and she said try not to remove any case studies there is no chance I can mention 9 with a few diagrams in 50 mins main section part!!!!

Which ones does everyone recommend I remove whilst still having balance?

Extrusive- Mauna Loa, Yellowstone, Soufriere Hills, Mid-Atlantic Ridge
Intrusive- Dartmoor Batholith, Northumbria Sills, Volcanic Plug Edinburgh
Fold- Himalayas
Fault- East Africa Rift Valley

Anyone good some good tips for writing a good evaluation for unit 4 ?

no we actually don't! this is because the question is solely asking about how these landscapes form, and describing the plate margins doesn't answer the question and it will waste so much of your time, as we only have an hour and a half which is nothing imo as we have to do so much.

however when talking about your landforms/scapes you do have to refer to what plate boundaries they're formed e.g shield volcanoes are formed at divergent margins or fold mountains are formed as a result of collision.

I would advise maybe doing a brief intro of a couple of sentences of what causes tectonic activity, but that's just it!!
hope this helps

thank you so much you're a life saver!!! My geography teacher who teaches this unit said to use the plate boundaries as 'models' to refer back to but then my geography teacher who teaches unit 3 said don't refer to them so we were all like what?! But thank you so much! I've saved around 10 minutes now!

We were told by teachers to either do it by location or by case study, either way evaluating each point made should get you into top marks?So I've structured mine like this:Intro, methodology, EXTRUSIVE ACTIVITY, VOLCANOES with subheadings Fissure, strato, shield and volcanic arcs and then i move onto INTRUSIVE IGNEOUS ACTIVITY with subheading sills, dykes and batholiths and then finally i do SEISMIC ACTIVITY with the subheadings fold mountains, displacement and EAR. Whilst doing this i compare each one to each other through out, and then in the conclusion i compare them all as a whole whilst stating that there are other contributions to the distinctively landscapes and forms. A range of diagrams are also used through out, I chose to do it by case study as i found it easier to make evaluative points while referring directly back to each type of landscape and the landforms within it. I don't know where to mention location in the conclusion just to help summarise where the most distintive landscapes and forms are concentrated around the world???

would you mind sending me this please?
