Knowing the rate of movement for the Pacific Plate from 4.7 to 1.6 million years ago was x cm/yr (ANSWER for question 6) , how does the rate and direction of Pacific Plate movement over the past 1.6 million years differ (Answer for question 8) from that of the older rate and direction that you were given.

Most of the part of the plate disappeared due to the early tectonics events

Explanation:

The pacific plate is the largest oceanic plate in the world and is 103 km square. The plate consists of Hawaiian islands and hot springs, the plate forms a convergent margin near the North American boundary.  The movement of the pacific plate is towards the northwest and has a sped / velocity of 52-102 mm per year. The oldest part of the plate disappeared away by the plate tectonic cycle in the early cretaceous period.
