In this way the rugged volcanic landscape of a mid ocean ridge is created along the plate boundary.

Seafloor spreading theory that oceanic crust forms along submarine mountain zones and spreads out laterally away from them. Further he claimed that continents would be pushed aside by the same forces that cause the ocean to grow. As two tectonic plates slowly separate molten material rises up from within the mantle to fill the opening. He suggested that new sea floor forms at the oceanic ridges and spread outwards from the line of origin.

Seafloor spreading real life examples. 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. The magnetism of mid ocean ridges helped scientists first identify the process of seafloor spreading in the early 20th century.

The concept of seafloor spreading was put forward by h harry hess an american geologist.

The concept of sea floor spreading. Basalt the once molten rock that makes up most new oceanic crust is a fairly magnetic substance and scientists began using magnetometers to measure the magnetism of the ocean floor in the 1950s what they discovered was that the magnetism of the ocean floor around. Benthos is the community of organisms which live on in or near the seabed the area known as the benthic zone.
