How do Earth's magnetic pole reversals provide evidence for plate tectonics?

O

A. Magnetic pole reversals can only be caused by plate movements.

O

B. Magnetic pole reversals only happen when the plates are

stationary

O

C. Magnetic striping occurs at subduction zones.

O

D. Magnetic stripes can be seen as you move away from ocean

ridges.

Option (D)

Explanation:

The magnetic pole reversals of the earth are found in the divergent type of plate boundary, where two plates move away from one another. The basaltic rocks are formed when magma erupts at the seafloor. These magmas are comprised of minerals that contain magnetic properties, which leads to the episodic reversal of magnetic polarity, every time it erupts. These normal and reverse polarity occur in the form of stripes that are parallel to the axis of the mid-oceanic ridge.

Thus, the magnetic pole reversal of the earth provides evidence for the plate tectonic activities.

Therefore, the correct answer is option (D).
