Daily Objectives #6 (September 11, 2008)

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

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

w For igneous rocks, explain the difference between volcanic (extrusive) and plutonic (intrusive) rocks.

w For igneous rocks, explain the difference between mafic and felsic rocks.

w For sedimentary rocks, explain the difference between chemical and clastic rocks, and tell how biochemical rocks fit into the picture.

w For metamorphic rocks, explain the difference between foliated and non-foliated rocks.

w Explain the difference between minerals and rocks.

w Explain how to use one of the mineral identification keys that are available online or distributed in the class. Tell what the important diagnostic properties of minerals are that one must investigate to use the key.
