Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. The Pacific-Farallon Ridge is a former mid-ocean ridge that existed between the Pacific and Farallon plates in the Pacific Ocean during the Tertiary period. Its appearance was in a north-south direction. About 60 million years ago, it might have extended at least 10,000 km (6,214 mi). Remnants of the Pacific-Farallon Ridge include the Explorer, Gorda, Juan de Fuca and the East Pacific ridges.A mid-ocean ridge is an underwater mountain range, typically having a valley known as a rift running along its spine, formed by plate tectonics. This type of oceanic ridge is characteristic of what is known as an oceanic spreading center, which is responsible for seafloor spreading.
