Homework: Study for the quiz on your rock

Remember the rock that you were assigned for the podcast?  The quiz will be on your rock only.  Bonus points will be available at the end of the quiz.

The quiz will be on Wednesday Nov. 18th.  A study guide should be filled out in our class today and will have all the info you will need for the quiz.

Lost your study guide?  If you know which rock you had (metamorphic, sedimentary, igneous) be able to answer these questions about it and you’ll do great!

How is your rock formed?
Example and ID
Famous Example
Human use
How is it different?
