Daily Objectives #5 (September 9, 2008)

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

Reviewing from last class: 

w Draw a diagram illustrating the internal structure of the earth.  Label and describe the major layers based on density (high, higher, and highest). and state (liquid, solid, gas).  Label and describe the major layers based on deformation characteristics (brittle/fracturing vs. plastic/flowing) 

w Define the terms lithosphere and asthenosphere.

w List the characteristics of the rocks that are the predominant components of the continental lithosphere vs. the oceanic lithosphere. 

w List the three major types of plate boundaries.  For convergent boundaries, list the three possible combinations of converging plates.

w Describe the geologic features that would be found at each of the plate boundaries listed above, and explain how each feature develops. 
 
w Tell what is expected of you in the homework assignments, "The Key to Minerals" or "The Key to Rocks".

New this time:

w Describe how igneous, sedimentary, and metamorphic rocks form.

w Working in a group, examine the lists of rock/sediment types you created for the "Rock Your State!" assignment.  Create a master list of all the rocks/sediments represented for all the states in your group.  Then, for each item on the list, categorize it as a sediment or as an igneous, sedimentary, or metamorphic rock.  For each of the rocks, subdivide the group into smaller classifications.  For sediments, organize the materials according to some logical principle, and state what it is.
