Early results of the Deep Sea Drilling Program clearly justified the conclusion that ________.
A)the oceans have not always contained most of Earth's water
B)the ocean basins are relatively young; most ocean basin rocks and sediments are Cretaceous or younger in age
C)proterozoic rocks are found only as seamounts in the deepest parts of the ocean basins
D)the youngest sediments were deposited directly on the oldest seafloor basalts

Question

Quizplus · Accepted Answer

The early results of the Deep Sea Drilling Program showed that most ocean basin rocks and sediments are Cretaceous or younger in age, indicating that the ocean basins are relatively young. This finding clearly justified this conclusion. Option A is incorrect, as the program did not provide evidence for or against the idea that the oceans have always contained most of Earth's water. Option C is incorrect because the program found Proterozoic rocks in places other than just the deepest parts of the ocean basins. Option D is incorrect because the program did not find evidence of the youngest sediments being deposited directly on the oldest seafloor basalts.
