    Also these are my case studies:

    Volcanic:
    Mid-Atlantic Ridge
    Deccan Plateau
    Shield Volcanoes
    Composite volcano
    Caldera
    Isle of Arran

    Seismic:
    East African Rift Valley
    Andes Fold mountains
    Faults- San Andreas

    It seems a bit heavy on the volcanic land-forms but thats because there are more.

    Also am i right in saying that all extrusive and intrusive landforms are volcanic?
    Andes Fold Mountains is caused by a destructive plate boundary between the Nazca and S.American plate, the formation is nothing do with seismic! It is caused where not all of the plate subducted below the other, so it has to go upwards!

    They usually only become distinctive once the overlying country rock has eroded, leaving them exposed. Batholiths are often an exception to this, as they can support orogenesis. Laccoliths can have a similar effect, but on a smaller scale, i.e. they cause the overlying rock to bulge, forming a hill.

    Once exposed, dykes and sills can be very distinct; research the Isle of Arran and Devils Tower.
    I think Devils tower is actually a volcanic plug! It's known as the 'magma that never made it'

    Does anyone think they will do a question based on seismic processes? If they do what is everyone planning on doing?

    I just read that it's a laccolith. Seems like geologists can't make their minds up.

    Really I thought Fold mountains were caused by stresses (seismic) in the continental crust which result in layers of rock within the crust folding up and down creating fold mountains :/

    Erosion and Weathering. Intrusive features do not impact landscapes until they have been uncovered by erosion and weathering (e.g. Isle of Arran). You must keep in mind that there is a difference between a landscape and landform.
    Ah yeah. But isn't intrusive activity also tectonic? and am I right in thinking that intrusive activity doesn't have to occur on plate boundaries?

    hmm i dont know, cause the ridge itself (the mountains and submarine volcanoes) is formed by the creation of new crust at the surface as the magma rises cools. Without the magma rising and cool now new crust would be formed and there wouldnt be a atlantic ridge so i think its a volcanic process :/
    This is what I was thinking, but the East African Rift valley was formed in a similar way and that is seismic

    Should you write in 1st person in the report e.g ' in this report i will be analysing the impact of seismic, extrusive and igneous processes on the landscape' etc'??
    also,
    do they actually check that the info you have said is actually from the source you have said it is and after mentioning the sources in your methodology do you need to mention them again in your analysis e.g' this information was gathered from the Geography textbook etc'?

    the process is similar but not the same. In the mid Atlantic ridge new crust is formed by magma risng and cooling however in the east african rift valley no new crust if formed rather the brittle crust in between the plates fractures causing it drop.

    Overall im not fan of this topic, the books don't clearly differentiate between seismic and volcanic landscapes rather most landscapes are the result of plate boundaries so i'm just using what i think is correct. Tectonic activity is just a heading and seismic and volcanic processes are just categories.

    that's my problem, Im so unsure of how to categorise it. because you can say that the convection currents put pressure upwards before flowing laterally, the upwards tension does create initial height, this is just furthered with the rising magma and cooling.

    that is true! it still counts as tectonic activity because igneous intrusions are formed through volcanic processes, however they do not need to be formed at a specific boundary, or even on the boundary. I think its just the fact that igneous intrusions do not actually have a visible impact on the landscape until they are uncovered through erosion or weathering

    my 3 different sections are convergent boundaries, divergent boundaries and then hotspots/igneous intrusions, with me mentioning that I've separated them due to the fact they do not need to be formed on boundaries

    I'm just trying to keep mine simple, anything which is formed by stresses in earth im categorizing as seismic while those being formed by rising magma from the mantle are volcanic. I don't know if my answers are right but as long as my report kind of makes sense it'll be ok i think. Many books and websites contradict each other and some landscapes can be classed as botu seismic and volcanic. Another issue is trying to differentiate between landscape and land form.

    To be honest just try your best and go with what you have got, for me its too late to change so what ever i have drafted even if its wrong im going to use.

    I definitely agree! Trust me I am in no means good at geography, ive been asking my classmates questions all day. But one thing to note, which can form a good argument, is the fact that the formation of many landscapes is often down to both seismic and volcanic processes. for example with island arcs, same as the ridge,the initial process is seismic and the movement of the plates, however it is then the volcanic activity that emphasises this

    Never write in first report perhaps instead write "in this report the". Yes you need to reference them in the analysis

    I've been told you can write in first person. For the framework you need to be telling them what you're going to be doing " in this report I will be examine..."

    Fold mountains can form both at collision and convergent plate boundaries

    I'm so confused on how to differentiate between seismic/tectonic/volcanic
    Case studies I've got:
    Divergent - Iceland and EARV
    Convergent - cascades, Caribbean and Himalayas
    Then I know SAF for transform and I just know there's Hawaii and Yellowstone as hotspots but not in detail
    Isle of Arran for intrusive activity - not confident on intrusive features
    Anyone please help how do I differentiate between tectonic volcanic seismic. Which case studies shall I use
