Sea Floor Spreading In Real Life

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.

Sea floor spreading in real life.

Further he claimed that continents would be pushed aside by the same forces that cause the ocean to grow. This graphic shows several ocean floor features on a scale from 0 35 000 feet below sea level.

The magnetism of mid ocean ridges helped scientists first identify the process of seafloor spreading in the early 20th century. Seafloor spreading theory that oceanic crust forms along submarine mountain zones and spreads out laterally away from them. 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. He suggested that new sea floor forms at the oceanic ridges and spread outwards from the line of origin.

Seafloor spreading is the usual process at work at divergent plate boundaries leading to the creation of new ocean floor. Benthos is the community of organisms which live on in or near the seabed the area known as the benthic zone. 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. In this way the rugged volcanic landscape of a mid ocean ridge is created along the plate boundary.

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.
