Using the ages (the numbers represent ages in millions of years) for each of the Hawaiian Islands, as well as the scale given in the accompanying figure, calculate the average rate of movement per year for the Pacific plate since each island formed. Is the average rate of movement the same for each island? Would you expect it to be? Explain why it may not be and why there are different ages for some of the islands.
