They discovered a pattern of reverse and normal polarity in the

rock bodies of the ocean floor that indicated that oceanic crust

was constantly being formed over time. Polarity shifts in the Earth

of radiometric dating, core samples were taken and dated,

confirming that the youngest rock is found at the ridge and rock

age advances with distance from the ridge.
