That Blue Square Thing - Geography Revision

Unit 5 Question - Plate Tectonics

This is a 20 mark exam-style question. The marks start small and build towards case study questions at the end - just like the real thing.

You want to aim to take around 25 minutes to do this question. Make sure your answers to the simple questions are accurate and that you develop the longer answers to explain points properly - don't leave things vague. Remember that 2 or 3 well developed points are better than 10 simple points. As always, try and use case studies to back up your answers.
