Question

magnetic striping is evidence of
a. aurora borealis
b. the van allen belts
c. seafloor spreading
d. earths gravity

Explanation:

Magnetic striping occurs at mid - ocean ridges. As new oceanic crust is formed at the ridge (due to seafloor spreading), the magnetic minerals in the basalt align with the Earth's magnetic field at that time. Over time, as the Earth's magnetic field reverses, these magnetic stripes (parallel to the ridge) are created. This is strong evidence for seafloor spreading.
Aurora borealis is caused by charged particles interacting with the Earth's atmosphere. The Van Allen belts are regions of high - energy particles trapped by the Earth's magnetic field. Earth's gravity is a fundamental force and not related to magnetic striping.

Answer:

C. seafloor spreading
