Review Sheet
for Exam #2 (October 20, 2009)
Dr. Sanders
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.
