Dr. Sanders
For Exam #1, you should be able to do the
following:
* List the
requirements for this course.
* Draw a
diagram illustrating the internal structure of the earth. On it,
clearly indicate and label the following:
crust ( show both oceanic crust and
continental crust)
mantle
inner core
outer core
lithosphere (show both oceanic
lithosphere and continental lithosphere)
asthenosphere
mesosphere
* Explain
what the difference is between the crust, mantle, inner core, and outer
core of the earth.
* Explain what the difference is between the lithosphere and
asthenosphere.
* Explain what the difference is between continental lithosphere and
oceanic lithosphere.
Plate Tectonics
* Read and explain world
maps that illustrate various geologic features:
hot spots, crustal thickness, depth of earthquake focus, locations of
volcanoes, geographic features, and plate boundaries. Download
the handout we used (MSWord format) by clicking here.
* Compile
information from the maps to discern patterns.

* Explain the
patterns in terms of plate tectonics.
* Describe the
direction of movement at each of the three types
of plate boundaries.
*
List and describe the geologic features you would find at each of the
following types of plate boundaries. Use sketches to illustrate
each type, and give real-world examples of each.
1) Divergent (also tell what type of plates are
typically found at these boundaries--continental, or oceanic?)
2) Convergent
A) Oceanic
and contintental plates converging
B) Oceanic
and oceanic plates converging
C) Two
continental plates converging
3) Transform
*
List the three major classes of rocks, and explain how they form.
* For each of the three major classes of rocks, tell in what
plate tectonic setting they are most likely to form.
Minerals
* List the
characteristics that all minerals
have in common.
* Explain the
difference between rocks
and minerals.
* Explain what is meant by the following terms used to
describe mineral
properties:
q hardness
q luster
q streak
q specific gravity
(similar to
density)
q cleavage
q color
q odor
q solubility
q
magnetism
* Demonstrate how to use mineral testing tools (e.g. streak plate,
scratch plate, dilute hydrochloric acid) to explore the
properties of hand samples of minerals.
* Explain how to
evaluate the mineral properties listed above for a
given mineral sample.
* Use a mineral key to associate names of minerals with their
diagnostic properties. (For fun,
visit the online
mineral identification key provided by the
Mineralogical Society of
America!)
* Explore the sedimentary
rock-forming minerals. Examine the mineral
samples in the following groups. Explore and describe the
properties of each
mineral, and determine what each group has in common. Finally,
assign
a name to each mineral using a mineral key.
First Group:
# 7, 17, 19, 20, 40,
43
Second
Group:
# 2, 18, 30, 46
Third Group (if you have time): # 14, 33, 34, 44
