AS geography revision
Start early…. There is a lot to learn. Use this as your starting point.
There is more help available on the geography revision pages of Moodle and also on AQA’s website, where you will find past papers, mark schemes and also examples of student answers (exemplars).
You can buy a CGP revision guide if you would like to (£5 from college) but also on Amazon and from WHSmith.
The bits that the CGP revision guide doesn’t have in it for AS Geography….
Graded long profile (only briefly mentioned, you could do with more info) Recurrence intervals / magnitude frequency analysis for flooding is not mentioned
Concordant / discordant coastlines
Landforms: geo’s, stumps, tombolo’s, barrier islands.
Coastal flooding- the CGP guide says tsunami but the syllabus wants storm surges so hurricane Katrina.
Factors affecting birth and death rates
Migration case studies
Optimum population and policies
Population and resource theories
You will do a mock in class to practise your timing.
Case studies: Each teacher will have slight variations in the case studies they use. Some of the key ones are listed in bold in the list below. There is a set of case study revision notes created by a past student on Moodle which you can use / adapt.
What follows is a list of what you should know for each of the 4 modules
The coastal system- make sure you know a list of the inputs, outputs and processes. Remember that there are so many potential stores that we don’t learn a list of them. The key idea with a system is that you change one part of it, the whole thing will be affected.
Waves: Know what creates waves and what influences how much energy the sea might have. Make sure you know what fetch means. Know the key wave terminology (frequency, length, height, period, crest, and trough) Know what makes a wave break. Know what swash and backwash are. Constructive and destructive waves: Make sure you know their key characteristics. Also understand that they usually occur in a cycle so beaches will be affected by both types of waves at different times and they each produce different beach profiles.
Understand wave refraction and how it concentrates energy on headlands.
It is also really important to appreciate that marine energy varies over time and space because of all the various factors therefore make sure you could explain why different parts of a coastline will receive different amounts and also why the same piece of coastline will receive different amounts at different times.
Know what longshore drift is and how it works- be able to explain it in terms of swash and backwash.
Tides: Understand what a tide is and the difference between spring and neap. Know what an amphidromic point is. Know that the UK has approximately 2 high and 2 low tides a day- the time between one high and the next is 12 hours, 25 minutes.
Sediment sources and cells. Know where sediment comes from- sea bed, beaches, rivers, cliffs. Also know what a sediment cell is and that there are 11 in total around the UK but these are sub divided into sub cells. Coastal processes – marine erosion (know the 4 types), transportation and deposition. You should know the factors affecting the rate of erosion on a coastline (marine energy, geology, amount of protection, dredging, presence of a beach, weather / climate etc)
Land-based sub-aerial weathering, mass movement and runoff. Know the types of weathering and mass movement.
Concordant and discordant coastlines- what do these terms mean? Can you explain why Lulworth cove formed?
Landforms of erosion: headlands and bays, blowholes and geos, arches and stacks, cliffs and wave cut platforms. Be able to recognise each of these and explain its formation if necessary. These sorts of questions can require you to explain using words or pictures....
