Part A – The Path to Plate Tectonics
1. Explain Wegener's hypothesis of
continental drift. Include in your explanation
the types of evidence he used to support
the hypothesis, and why his idea did not
gain wide acceptance at the time.
2. Describe some of the scientific
advancements that provided evidence for
plate movement and led to the Theory of
Plate Tectonics.
3. Recognizing that the continents of North
America and Africa were once joined as
part of Pangaea, how does the Theory of
Plate Tectonics explain why those
continents are now separated by the
Atlantic Ocean and still moving apart?
Part B – Plate Tectonics in Action
You may want to do some research beyond
the textbook to get an idea for what these
features look like in cross-section view.
Hand drawings or those created using
drawing programs are acceptable. It is fine
to model after an existing diagram, but all
work should be original.
4. Divergent plate boundary - create a time-
series of drawings (at least 2 drawings) to
illustrate seafloor spreading at the MOR
with as much geologic detail as possible.
See section 2.4.2 of the textbook for an
idea. Include a title for this drawing, label
the main features and provide a legend if
