how do magnetic stripes of iron in ocean rock provide evidence of seafloor spreading? they show when earth’s 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.

how do magnetic stripes of iron in ocean rock provide evidence of seafloor spreading? they show when earth’s 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. As magma cools and solidifies, iron - rich minerals align with Earth's magnetic field. Magnetic stripes on either side of a mid - ocean ridge are mirror images, which is evidence of seafloor spreading. Earth's pole reversals are related but not the direct evidence of spreading. Density change and mineral composition differences are not the main evidence shown by magnetic stripes.

Answer:

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