why do rocks on the ocean floor form a pattern of magnetized stripes? the rocks contain iron that points in the direction the rocks move away from the ridge. the rocks are composed of different materials depending on when they formed. the rocks change shapes as a result of the pushing and pulling of seafloor spreading. the rocks contain iron that points in different directions depending on earths polarity.

Answer

Brief Explanations:

The iron - rich minerals in ocean - floor rocks act like tiny magnets. Earth's magnetic field has reversed many times over geological history. When new oceanic crust forms at mid - ocean ridges and cools, the iron in the rocks aligns with the Earth's magnetic field at that time. So, the rocks contain iron that points in different directions depending on Earth's polarity, creating the pattern of magnetized stripes.

Answer:

The rocks contain iron that points in different directions depending on Earth's polarity.
