The east pacific rise is a mid ocean ridge that runs through the eastern pacific ocean and separates the pacific plate from the north american plate the cocos plate the nazca plate and the antarctic plate. Seafloor spreading is a process that occurs at mid ocean ridges where new oceanic crust is formed through volcanic activity and then gradually moves away from the ridge. Seafloor spreading theory that oceanic crust forms along submarine mountain zones known collectively as the mid ocean ridge system and spreads out laterally away from them.

Seafloor spreading occurs along mid ocean ridges large mountain ranges rising from the ocean floor. Seafloor spreading is a geologic process where there is a gradual addition of new oceanic crust in the ocean floor through a volcanic activity while moving the older rocks away from the mid oceanic ridge. These sounds have to have been made by very large objects or possibly creatures with most scientists believing the sounds are large icebergs scraping the ocean floor. The more intensive types of deep sea mining involve actually removing parts of the seabed or seamounts which would kill any life living there and would take decades at the very least for the.

But what if it s not. This idea played a pivotal role in the development of the theory of plate tectonics which revolutionized geologic thought during the last quarter of the 20th century. Seafloor spreading definition a process in which new ocean floor is created as molten material from the earth s mantle rises in margins between plates or ridges and spreads out. Fisheries across the world are a shade of their former abundance.
