Unit 4 Objective 1 Geosphere Corrections
a. Draw the layers of the Earth in order: crust, lithosphere, inner core, outer core, asthenosphere, Moho
boundary, and mantle.
b. Draw convection cells in the correct layer on your previous drawing.
c. Fill in the following charts on a separate sheet of paper:

consistency?
What is unique
about it?

Ocean Drilling
Earthquake patterns
B. why is Wegner’s tale of the continental drift a sad and wrong one?
Unit 4 Objective 3 Plate boundaries and Mechanisms
a. Draw a picture and write a sentence description for each the six types of plate boundaries we learned
about.
b. Be able to identify anything off of the plate boundary diagrams from the study guide. The instructor
will quiz you on this.
c. Describe (with words, not pictures) each of the 3 plate mechanisms (slab pull, ridge push, and mantle
plume) and which arm of the convection cell they are on.
Unit 4 Objective 4  Earthquakes
a. Draw a 4 panel cartoon with 1) a man standing 2) a man being shook by a P-wave 3) a man being
shook by a S-wave 4) a man being shook by a surface wave.
b. Draw a picture of a seismogram and a seismograph. Please be sure to label which is which.
c. Describe elastic energy and how it relates to an earthquake.
d. Draw a picture of how a seismologist uses seismograms to find an earthquake epicenter.
e. Define an epicenter and a focus.
Unit 4 Objective 5 RYM
a. How do you make….?
1) Sedimentary Rocks?
2) Igneous Rocks?
3) Metamorphic Rocks?
b. Define erosion and how it has changed on Earth.
c. Where doe sediment come from? Why is it needed in soil?
d. Describe how a loss of vegetation can help a mass movement to move quicker.
e. Define mechanical and chemical weathering and give 2 examples.
f. Write a hypothesis and come up with 2 variables for the question “Why do maggots grow out of
mushrooms?
