D. Reversal of Earth's magnetic field
Explanation:
The earth's magnetic field changes over time and this causes changes in the direction of magnetization of magnetic elements or minerals in rocks.
Our magnetic field is widely believed to originate from activities within the outer core where molten iron and nickel moves. The flow of these molten elements results in the production of the magnetic signatures on earth surface.
Some elements and minerals within rocks are capable of recording the direction of magnetic fields at a period in time. Before magma cools, such minerals in these rocks aligns their poles to that of the prevailing direction of the earths magnetic field. This is how the magnetic changes at the mid-oceanic ridges are recorded.
Answer:
The process of seafloor spreading is responsible for "creating magnetic changes" along mid-ocean ridges.
