Need help on the question below...I know it is not C or D
The formation of metamorphic rocks depends on all of the following except
a. the composition of parent rocks
b. Earth's magnetic field
c. temperature
d. pressure
Thanks

  • Science -

    Pressure is he best answer.

  • To Dr Jane--Science -

    I disagree with your answer although I'm certainly no expert on rocks/geology processes, etc. Pressure is a very real part of metamorphic rock formation.
    See http://en.wikipedia.org/wiki/Metamorphic_rock

    I can remove your answer if you wish.
