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. As new oceanic crust forms at mid - ocean ridges and moves away, the iron in the rocks aligns with Earth's magnetic field at the time of rock formation. Since Earth's magnetic polarity has reversed many times in the past, the iron in the rocks points in different directions depending on Earth's polarity, creating a pattern of magnetized stripes.

Answer:

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