for Exam #2 (October 20, 2009)
For the exam, you should be able to do the following:
Rock Your State! In-class work
w Make a list of all the kinds of rocks and sediments found in the states you researched.
w For each item on your master list of rocks and sediments, categorize it as a sediment, igneous rock, sedimentary rock, or metamorphic rock.
w For each type of rock (ig, sed, meta), subdivide the group into smaller sub-classifications.
w Logically organize the information your research reveals about the sub-classifications of igneous, sedimentary, and metamorphic rocks; then, apply it to the description of hand samples.
w Use your knowledge of rock classification to describe the characteristics of igneous rocks.
w Describe the sub-classifications of sedimentary rocks and metamorphic rocks, and apply that information to hand samples.
w Explain the relationship between minerals and rocks.
w Describe some of the characteristics of minerals that allow us to classify them and discern their properties.
w Describe how to explore and characterize mineral properties, including color, hardness, density/specific gravity, mineral cleavage, luster, and reaction to acid.
w Use your knowledge of rock classification to describe the characteristics of clastic (detrital) sedimentary rocks.
w Describe the steps in forming sedimentary rocks, including weathering of pre-existing rocks, erosion, transport, deposition, and lithification (including cementation and compaction).
w Describe the characteristics of chemical sedimentary rocks.
w List the minerals that can form chemical sedimentary rocks, and tell what rock each one forms.
w Demonstrate how to recognize chemical sedimentary rocks in hand sample.
w List the processes that lead to metamorphism.
w Use your knowledge of rock classification to describe the characteristics of metamorphic rocks.
w Describe the changes that can affect rocks to form metamorphic rocks, including foliation and recrystallization.
w Draw a diagram illustrating the processes and materials involved in the Rock Cycle. Include igneous, sedimentary, and metamorphic rocks, as well as sediments and magma.
w Geotectonics: Describe the three kinds of geotectonic plate boundaries, and the geologic features that form at each one.
w Describe the three possibilities for convergent boundaries, including the different combinations of lithospheric plates.
w Describe the plate tectonic setting in which each of the three kinds of rocks form.
