how do magnetic stripes of iron in ocean rock provide evidence of seafloor spreading? they show when earths poles reversed. they show how the density of the seafloor has changed. they reveal a matching pattern on either side of the ridge. they reveal differences in the mineral composition of newly created rock.

Answer

Brief Explanations:

Seafloor spreading creates new oceanic crust. Magnetic minerals in the cooling magma align with Earth's magnetic field at the time. As the seafloor spreads, a symmetrical pattern of magnetic stripes forms on either side of the mid - ocean ridge, showing the periodic reversals of Earth's magnetic field. This matching pattern on either side of the ridge is evidence of seafloor spreading.

Answer:

They reveal a matching pattern on either side of the ridge.
