Answer:
A. The age of seafloor decreases as you move away from the mid oceanic ridges.
Explanation:
- The scientist can determine the age of the seafloor by evidence collected by dating the rocks found near the seabeds, the rocks that were found far away from the mid-oceanic ridges and seafloor were considered to be of the old or ancient period as compared to the rocks that were seen near the surface of the ridges.
- This is because the spreading of lavas, on or near the surface of the ridges creates lava plumes that tend to move up and these on cooling down get settled with the same magnetic patterns or alignment that of earth.
- Thus distant rocks have different age compositions due to the molten matter that forms the basaltic rocks in tectonic plates.
