pressure and temp of metamorphic rocksgreenspun.com : LUSENET : Introductory Geology, Oswego State : One Thread
I thought that both of these contributed to a rock turning into magma. I thought that you stated that the rock had to be heated to 600 degrees to turn into a liquid. Could you please explain what temperature does to the rock along with what pressure does so I can revise my notes

I have in my notes that The higher the pressure the more heat is required to melt the rock. The higher pressure makes the rock want to stay a soild. However different rocks melt at different tempertures due to their different compostions and water content. I hope this helps.
