Questions -

1. Using the map above, calculate the rate the Pacific plate has moved over the past 1.9 million years (in cm/yr).  (Hint: measure the straight line distance between the respective dots on the map.)

2. Using the map above, calculate the rate the Pacific plate moved from 1.9 million years ago to 5.1 million years ago (in cm/yr).  (Hint: find the difference between 1.9 million & 5.1 million years before dividing)

3. Has the Pacific plate sped up or slowed down? (Hint: look carefully at the timeframes in the two previous questions.)

4. What general direction is the Pacific Plate currently moving?

5. Using the rate you calculated in question 1, how far will the Pacific plate move in the next 50 years (in cm)?
