Climate change leaves its mark on the sea floor? Maybe not, study says

The texture of the ocean floor is determined by the enormous stretching and cracking that takes place at the mid-ocean ridge, where tectonic plates are pulling apart and magma is rising to form new sea floor. On either side of the ridge, rows of abyssal hills form and then move away as the plates pull apart over time. Exactly how those forces combine to influence the size and shape of the hills, however, hasn't been entirely clear.
