Fossils from the sea floor became older with increased distance from the ridges.

Question

Quizplus · Accepted Answer

This statement is true because as new oceanic crust is formed at the mid-ocean ridges, it moves away from the ridge at a rate of a few centimeters per year. As it moves away, it cools and contracts, causing the oceanic crust to become denser and sink deeper into the mantle. As a result, the seafloor gets older with increasing distance from the ridge. Fossils that are preserved in the seafloor sediment also get older with distance from the ridges.
