What explains the fact that the polarities of rocks alternate multiple times as you move away from the mid-ocean ridge? a. plate tectonics b. paleomagnetism c. subduction zones d. seafloor spreading

Answer;

B. Paleomagnetism

Explanation;

- Paleomagnetism is the study of the record of the Earth's magnetic field in rocks, sediment, or archeological materials. Certain minerals in rocks lock-in a record of the direction and intensity of the magnetic field when they form.

-Magnetic studies revealed that the ocean floor was comprised of parallel bands of crust having alternating magnetic polarity.These magnetic bands were symmetric about the mid-oceanic ridge.

-The explanation of magnetic striping by paleomagnetism convinced scientists that new oceanic crust was being continually formed at mid-oceanic ridges. Seafloor spreading was accepted as a reality.
