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
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.
w
Tell what the important diagnostic properties
of minerals are that one must investigate to use the key (for example, the
mineral's luster, hardness, cleavage, color, odor, reaction with acid, and so
on).

w
Demonstrate that you can use a mineral key to
fully describe and identify a mineral specimen in terms of its properties.
w
Use a mineral key to determine the name of a mineral
specimen based on its properties.
w
Examine hand samples of igneous rocks
and tell whether they are of mafic, intermediate, or
felsic composition.
w
Examine hand samples of igneous rocks
and tell whether they are intrusive or extrusive
rocks.
w
Examine hand samples of igneous rocks
and characterize their cooling rate as slow, fast, or virtually
instantaneous.
w
Describe the characteristics of
granite and basalt, and identify these rocks in hand
sample.
