As two tectonic plates slowly separate molten material rises up from within the mantle to fill the opening.
Sea floor spreading in real life.
Seafloor spreading theory that oceanic crust forms along submarine mountain zones and spreads out laterally away from them.
He suggested that new sea floor forms at the oceanic ridges and spread outwards from the line of origin.
In this way the rugged volcanic landscape of a mid ocean ridge is created along the plate boundary.

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.
This graphic shows several ocean floor features on a scale from 0 35 000 feet below sea level.

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 real life examples.
Seafloor spreading is the usual process at work at divergent plate boundaries leading to the creation of new ocean floor.
The magnetism of mid ocean ridges helped scientists first identify the process of seafloor spreading in the early 20th century.
Further he claimed that continents would be pushed aside by the same forces that cause the ocean to grow.
Benthos is the community of organisms which live on in or near the seabed the area known as the benthic zone.

The concept of seafloor spreading was put forward by h harry hess an american geologist.
Continental shelf 300 feet continental slope 300 10 000 feet abyssal plain 10 000 feet abyssal hill 3 000 feet up from the abyssal plain seamount 6 000 feet.
This community lives in or near marine sedimentary environments from tidal pools along the foreshore out to the continental shelf and then down to the abyssal depths the benthic zone is the ecological region on in and immediately above the seabed including the sediment surface.
