Earth Science FS#12 - 1 Bill Frye Name___________________________________ Pd. __ Date_______ Earth Science Chapter 12 -- Fryesheet Many drawings in this chapter – use the back or other paper for the drawings. Also, some questions are optional and will be assigned as time permits. You must pay attention to in-class announcements so you know which questions will be discussed and which questions are optional. (Just because a question is made optional doesn’t mean it is not important; it simply means we won’t have time to discuss it in class and it will not be on a test.) ======================== Section 1===========pp. 342 - 347=========================== Objectives 1.
