What questions about metamorphism can you ask when looking at any metamorphic rocks?

The new ELI today is 'Questions for any rock face 9: metamorphic rock; what questions about metamorphism might be asked at any metamorphic rock exposure?'

Take your pupils to an exposure of metamorphic rocks where the features are clearly visible and preferably, where there is also evidence of the former rock type, and ask the questions provided. The answers will help pupils distinguish metamorphic rocks and understand the processes by which they formed.
