Question 245990: Using the existing elevation of the Big Island of Hawaii, and an assumed lava flow-rate from the hot spot of 300,000 cubic-meters per second, how long did it take to form the Big Island of Hawaii? Please show assumptions, formulas, and your calculation. Answer by oberobic(2304) (Show Source):
You can put this solution on YOUR website! What is the area of the island in square meters? Call it A.
What is its average elevation in meters? Call it E.
A*E = volume of the island above sea level in cubic meters.
Divide by 300,000 cubic meters/second to yield the number of seconds.
Convert the seconds to minutes or to hours or to days or to years.
