The state of Hawaii is made of eight large islands and over a hundred smaller islands. The island of Hawaii is the most southeastern of the eight largest islands and is also closest to the seafloor spreading center from which the Pacific plate originates, about 5,600 km farther to the southeast. Assuming equal sedimentation rates for the entire region, what should be the location of the thickest sediment layer, and thus the area with the greatest diversity of fossils above the oceanic crust?
