Every 50-500 km, the mid-ocean ridge is offset sideways right or left by transform faults (found where two plates slide sideways against each other). The ridge also has many smaller lateral offsets which, together with larger transform faults, divide the mid-ocean ridge into many segments. Along the crests of the volcanoes of the mid-ocean ridge, cracks allow the near-freezing sea water to seep deep into the hot new crust.
