Question

multiple choice question
the thickness of pelagic sediments ______ with increasing distance from mid - ocean ridges.

decreases

does not change

increases

Explanation:

Pelagic sediments accumulate over time as oceanic crust moves away from mid - ocean ridges. The longer the time (which corresponds to a greater distance from the ridge, as the crust is moving), the more sediment can accumulate. So the thickness of pelagic sediments increases with increasing distance from mid - ocean ridges.

Answer:

C. increases (assuming the options are labeled A: decreases, B: does not change, C: increases)
