MAGMA FROM SOURCE TO SURFACE

Well done to all of you who scored 9/10 and 10/10 for your questions and comments to Prof Menzies yesterday! He again went away impressed with your enthusiasm, ability to think and your willingness 'to be curious'. 

My favourite quote from yesterday:
'Eyjafjallajokull eruption significantly improved the air quality in London and at Heathrow in particular.'

Some detailed concepts were covered I thought you coped really well!
