Question

Can someone over look my anwsers please and help me find how to solve for number 4 please, thank you.

Locations Measured Actual Distance Distance on (i mm or inches) Age Difference Rate of Plate Movement (mm or inches per year) (in years) Map (in mm or inches) Kaua i to Hawairi 0'ahu lo Hawari Moloka'i to Hawaii Kaua'i to O'ahu Kaua'i to Moloka'i 40mm Based on the average of your five answers in problem 1, what has been the approximate rate of movement of the Pacific Plate in the area of the Hawaiian Islands over the last 5.1 million years?3o 2. 3. Midway Island, to the northwest of Hawai'i, is also part of the Hawaiian chain and is LPA believed to have been produced by the same hot spot. Midway is about 2430 kilometers (1510 miles) from the Kilauea volcano on Hawai'i. Use the average rate of plate move calculated in problem 2 to estimate the age of volcanic rocks you would expect ment you to find on Midway Island. The actual age of the volcanic rock on Midway is about 27.7 million years. Suggest a reason why your answer for problem 3 differs noticeably from this 4.

Explanation / Answer

The actual age of the volcanic rock on Midway is not coming accurate by our calculations because we have considered avergae speed of plate movement that is 113.76 mm/year whereas there may be a condition that the actual plate movement speed might be less than 113.76.

If the correct age of Volcanic rocks in Midway is 27.7 million years that is 27700000 years. This means

Speed of plate = 2430000000/27700000 = 87.72 mm/year.

So the correct speed of plate will be 87.72 mm/year.
