January 6 Error on page 3 of the syllabus: The textbook is Lutgens and Tarbuck, 12 th edition, not Chernicoff and Whitney. Reading Guide quiz over Chapters 4 and 5 next Monday Please bring a pencil to lab this week If you are having trouble getting a text book, see Bob after class. Questions on the syllabus review?

Syllabus Quizzes- no makeups, but you start with 10 points
5
Syllabus Quizzes- no makeups, but you start with 10 points Reading guides may be used on quizzes, but no book or notes
6
Syllabus Quizzes- no makeups, but you start with 10 points Reading guides may be used on quizzes, but no book or notes Extra textbooks by other authors in SC 110 – the Geology study room
7
Recommendations Attend class every day! Take good notes in class (not just what I put on the screen) Write out group questions given in class and the answers after class Read the text before we discuss topics in class. Form a study group

What determines the viscosity?
15
Silica content of the magma Silica content of the magma High silica rhyolite
16
What determines the viscosity? Silica content of the magma Silica content of the magma High silica rhyolite Slightly lower silica dacite
