Assignment:
Directions: Use the map and the following information to determine the rate of motion of the Pacific Plate over the Hawaiian hot spot.
The volcano that formed the Island of Niihau is 4.89 million years old.
Step 1
Rate is the distance traveled over a period of time. The distance traveled is equal to the distance from the present location of the hotspot (southeast Hawaii) to Niihau. Time is the age of the island.Start by measuring the distance from southeast Hawaii to Niihau.Use the scale on the map.
Step 2
To determine the average rate of motion for the Pacific Plate, divide the distance to Niihau by the age of the island.
Step 3
Note that your rate is in kilometers/million years (km/Ma). Convert your answer to centimeters per year (cm/yr).
Step 4
How far will the plate move in 50 years?

Directions: Use the map and the following information to determine the rate of motion of the Pacific Plate over the Hawaiian hot spot. The volcano that formed the Island of Niihau is 4.89 million years old. o 100 KILOMETERS o 50 MILES (Imap courtesy of the USGS) PACIFIC OC'EA N1 Rate is the distance traveled over a period of time. The distance traveled is equal to the distance from the present location of the hotspot (southeast Hawaii) to Niihau. Time is the age of the island. Question #1 Start by measuring the distance from southeast Hawaii to Niihau. Use the scale on the map. The distance is Ian. Question #2 To determine the average rate of motion for the Pacific Plate, divide the distance to Niihau by the age of the island. The rate of plate movement is km/Ma (kilometers per millions of years). Question #3 Convert your answer to crn/yr (centimeters per year). The rate of Pacific Plate movement is ______ centimeters per year. Question #4 Using this rate, how far will the Pacific Plate move in 50 years? _ 11
