WebJun 27, 2024 · Mid-ocean ridges do not form straight lines but are instead offset in many places by fracture zones, or transform faults. Fracture zones are thought to occur due to zones of weakness in the pre-existing continent before it was rifted apart. Most mid-ocean ridges are divided into hundreds of segments by fracture zones. http://web.crc.losrios.edu/~jacksoh/lectures/marinegeology.html
