Question

what is the orientation of the magnetic stripes of iron contained in rocks that support the idea of seafloor spreading?
○ east and west
○ north and east
○ south and west
○ north and south

Explanation:

Seafloor spreading occurs at mid-ocean ridges, where new rock forms and records Earth's magnetic field. Earth's magnetic field aligns north-south, so the iron in these rocks (and the resulting magnetic stripes) orient north and south, mirroring the field's direction as the seafloor spreads outward from the ridge.

Answer:

north and south
