Figure 23.3
-Hawaii is the most southeastern of the seven islands and is also closest to the seafloor spreading center from which the Pacific plate originates,which lies about 5,600 km farther to the southeast.Assuming equal sedimentation rates,what should be the location of the thickest sediment layer and,thus,the area with the greatest diversity of fossils above the oceanic crust?
A)between the island of Hawaii and the seafloor spreading center
B)around the base of the island of Hawaii
C)around the base of Kauai,the oldest of the Hawaiian Islands
D)where the islands are most concentrated (highest number of islands per unit surface area)

Quizplus · Accepted Answer

The thickest sediment layer and thus the area with the greatest diversity of fossils would be around the base of Kauai, the oldest of the Hawaiian Islands, because sedimentation would have had the longest time to accumulate there.
