Daily Objectives #5  (September 12, 2006)                                                                        Dr. Sanders

Reminder:  Exam #1 is scheduled for September 19, one week from today!

By the end of today’s class, you should be able to do the following:

REVIEW: Describe the lithosphere and asthenosphere, sketch a diagram showing the internal structure of the earth and show where they occur, and explain how they differe in terms of their temperature and rigidity.

REVIEW: List the two types of lithosphere (oceanic lithosphere and continental lithosphere) and describe how they differ in terms of their thickness and density.

REVIEW: Describe, sketch a diagram of, and explain the geologic features you would expect to find at each type of plate boundary.  (For convergent boundaries, consider all three possible combinations of plate types!)  Give a real-world example for each situation.

*  List the three major groups of rocks and briefly explain how each type forms.

*  List some characteristics of rocks that might help you determine whether a rock is igneous, sedimentary, or metamorphic.

*  For each of the three major groups of rocks, give a few plate tectonic settings in which one might find that type of rock forming.

*  Complete the sentence, "Most rocks are made of _________."

*  Given several samples of different minerals, make observations about them and sort them into groups based on their properties.
