That Blue Square Thing - Geography Revision

Unit 5 Question - Plate Tectonics

WARNING! These pages are now very old. They were last updated in 2008 and the content applies to an old version of any geography syllabus currently active in the UK.
I've kept them here because there might be something useful for someone and the general marking principles aren't all that different. But be aware that it's old and out of date (the stuff on the Google Earth page in particular may not work at all)

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.

Print the page and have a go at the questions on paper. Then mark your work yourself using the markscheme provided.
