Geology Unit Review
The test will cover the entire geology unit including plate tectonics, earthquakes, the
structure of the Earth, rocks and minerals, the influence of the last ice age on the Maine
landscape and other topics covered in this unit. Go over each of your handouts (paying careful
attention to questions that accompanied the handouts), class notes, labs and your quizzes over this
section. The questions that follow are not intended to cover all of the material you are responsible
for on this test. Completing this handout is just one step in preparing for this step. You are
expected to review all of your material and be familiar with vocabulary and concepts covered in
this unit.
1.
Draw a picture that shows how tectonic plates move at divergent, convergent and transform
plate boundaries.
2.
Compare the speeds of P- and S- waves.
3.
What happens when P-waves hit the core?
4.
What happens when S-waves hit the core?
5.
How do you find lag time?
What is the purpose of finding lag time? (How is this information used?)
6.
Compare and contrast how igneous, sedimentary and metamorphic rocks form.
7. – 12. For each of the following statements, determine if they are true or false. If they are
false, change a word or phrase to correct them.
7.
Plutons are intrusive igneous formations.
8.
During the last ice age, ice sheets extended as far south as Cape Cod, MA.
9.
Eskers are scratches left in the bedrock by moving glaciers.
10.
Sandstone is an intrusive igneous rock.
11.
Extrusive igneous rocks generally have large crystals.
12.
Rocks are to minerals as flour and sugar are to baked goods.
13
Subduction zones occur along _____________plate boundaries.
14.
________________ are intrusive igneous formations that cut horizontally across the country
rock.
15.

a. wind; b. glacial meltwater; c. glacial ice
16.
Which of the following areas are particularly vulnerable to earthquakes.
a. sills; b. eskers; c. plate boundaries; d. mantle; e. none of the above
17.
Draw a diagram of the Earth and label the following. Inner core, mantle, lithosphere,
outer core, crust, lithosphere
18.
Which layer is the thinnest?
a.. Inner core; b. mantle; c. lithosphere; d. outer core;
d. crust;
e. lithosphere
19.
Name three features of the landscape that are left behind by glaciers.
20.
Describe how Blue Hill Mountain formed. Your answer should include a discussion of depth,
plutons, country rock, weathering and erosion and these terms should be defined as part of
your answer.
21.
Describe two differences between continental crust and oceanic crust.
