The Earth's mid-ocean ridges display systematic changes in depth and shape, which subdivide the ridges into discrete spreading segments bounded by transform faults and smaller non-transform offsets of the axis. ... For over 9,500 km of mid-ocean ridge examined, leading ridge segments in the 'hotspot' reference frame...

numerical models of plate separation, dyke intrusion and faulting require at least two distinct mechanisms of fault formation at ridges to explain these observations. Plate unbending with distance from the top of an axial high reproduces the observed dip directions and offsets of faults formed at fast-spreading centres.

Mid-Ocean Ridges are places where the Earth's tectonic plates are gradually moving apart, and as they do, magma rises up to fill the gap, sometimes leading to submarine volcanic eruptions.

Mid-ocean ridges have different shapes (morphology) depending on how fast they are spreading, how active they are magmatically and volcanically, and how much tectonic stretching and faulting is taking place.

The mid-ocean ridge is a continuous chain of volcanoes on the ocean floor where lava erupts and the crust of the Earth is created. Nearly every day, somewhere on the crest of the mid-ocean ridge, there is likely to be an eruption of lava or an intrusion of magma that builds the ocean crust. ... mid-ocean ridge interactive...

And why are the stripes symmetrical around the crests of the mid-ocean ridges? These questions could not be answered without also knowing the significance of these ridges. ... This process, later called seafloor spreading, operating over many millions of years has built the 50,000 km-long system of mid-ocean ridges.

This heated layer is the source of lava we see in volcanos, the source of heat that drives hot springs and geysers, and the source of raw material which pushes up the mid-oceanic ridges and forms new ocean floor.
