Question

How do magnetic stripes on the ocean floor serve as evidence for seafloor spreading? A. Their symmetry on either side of the mid-ocean ridge shows that new crust is created, then split. B. They show that island arc volcanism creates new oceanic crust at the mid-ocean ridges. C. Their symmetry on either side of mid-ocean ridges shows that transform boundaries are sliding boundaries. D. Their patterns show that the Earth's magnetic field reverses every few hundred years, on average. E. the magnetic stripes correlate with time.

Answer 1

Answer:

D. Their patterns show that the Earth's magnetic field reverses every few hundred years, on average

Explanation:

• The seafloor spreading is a process of the mid-oceanic ridges where the oceanic crust is formed by volcanic activity and it gradually moves on both sides of the ridges.

• The spreading takes place through the magma which are magnetized by the earth's magnetic field and spread in the direction of positive and negative properties.
