i have a test tomorrow and i have to review!!! TNX FOR YOUR TIME EVERYBODY.
1- how would an igneous rock the cooled deep beneath the earth's surface appear different from an igneous rock the cooled on the surface? why is there a difference?
2.describe the grain (crystal) size or texture you would expect to find in an igneous rock the formed at he bottom of the ocean at a mid ocean ride. why would this texture be different from a rock that cooled from lava from a surface volcano?
3. compare and contrast regional metamorphism from local metamorphism. where would you expect to find each? how much rock material is affected? what causes are most important for each?
