Hi there!
I hope you're able to give me a bit of assistance! As part of a geography assignment, I needed to find geography terms that I didn't know the meaning of, and research them. I've managed to find definitions for all except two:
* Vertical joints (on mountains)
* Contact zone (where two rock types meet - on a big scale)
I only need short explanations!
Thanks for your help - it is much appreciated!!!
