The Final Countdown is here to help you prepare for your final AQA GCSE geography exam. Following our weekly exercises will prepare you to take on the examiner.
This week you will revise coastal landscapes in the UK. It would help if you covered the following:
The coast is shaped by a number of physical processes.
- weathering processes – mechanical, chemical
- mass movement – sliding, slumping and rock falls
- erosion – hydraulic power, abrasion and attrition
- transportation – longshore drift
- deposition – why sediment is deposited in coastal areas.
Distinctive coastal landforms are the result of rock type, structure and physical processes:
- How do rock type and structure affect coastal landforms?
- Characteristics and formation of landforms resulting from erosion
– headlands and bays, cliffs and wave-cut platforms, caves, arches and stacks
- Characteristics and formation of landforms resulting from deposition – beaches, sand dunes, spits and bars.
- An example of a section of coastline in the UK to identify its major landforms of erosion and deposition.
Different management strategies can be used to protect coastlines from the effects of physical processes
The costs and benefits of the following management strategies:
- hard engineering – sea walls, rock armour, gabions and groynes
- soft engineering – beach nourishment and reprofiling, dune regeneration
- managed retreat – coastal realignment.
- the reasons for management
- the management strategy
- the resulting effects and conflicts.
Use one of the three strategies below to revise these areas.
Create flashcards to summarise the areas above. We’ve got a guide to creating flashcards if you need support.
Complete the revision quizzes covering river landscapes in the UK (you completed revision activities on this area last week!).
