Physical Geology Helpful Lab Hints
Exercise 17: Plate
Tectonics
Problem 3
- a. Plot the data as indicated on the annotated
graph below.
- annotated
graph from p.
337
- "Best fit" means a straight line
that comes as close as possible to all of the points on that
segment. In this case, the segments are given as Kiluea to Laysan
and Laysan to Suiko
- Do the lines have the same slope? Is
one steeper? On this graph, the steeper the line, the __________
the rate of plate motion. (faster or slower? select one)
- b. Rate = distance/time. The
annotated chart indicates which numbers to use.
- c. How did the chain form? Refer
to the textbook Chapters 3 & 4 (discussion of "hot spots").
- If the islands are a record of the plate
moving over a "hot spot" how did the chain get a bend?
What happend to the direction the plate was moving?
- When did this happen? Hint: Refer to
the annotated chart above.
