The 97-2003 conversion of a powerpoint presentation I've made about plate tectonics. Please note that there are sounds on each transition to stop me from losing my concentration (because I'm weird like that) so if you don't like them, then mute it!
Also, on slides with lots of information, you'll notice there are lots of different colours. I didn't do this just for the sake of it, I did it because whenever there's lots of writing all of the same colour, I find it very hard to take it in without beginning to daydream (like I said, I'm weird) so I'm sorry if it's off-putting. xD
I hope it helps you to revise, and good luck in the exam! :)
