Where Does Seafloor Spreading Take Place

Sea floor spreading takes place at the mid ocean ridge where two oceanic plates are spreading pulling apart from one another.

Where does seafloor spreading take place. Seafloor spreading takes place at the boundaries of divergent plates whereby as the divergent tectonic plates move away from each other hot convectional currents from the mantle cause the lithosphere the ocean crust to become less dense ductile and brittle and therefore rise above the surrounding crust to form a submarine mountain. Subduction takes place at. The mid atlantic ridge and east pacific rise are examples of midocean ridges. Pangea supercontinent that incorporated almost all of earth s landmasses in early geologic time.

The new material splits apart the old material and pushes it outward from the ridge. They are the shallowest major features of the seafloor. In sea floor spreading new crust is added at a. Fully assembled by the early permian epoch some 299 million to 273 million years ago it began to break apart about 200 million years ago eventually forming the modern continents and the atlantic and indian oceans.

Seafloor spreading takes place at midocean ridges and produces basalt the rock that makes up the oceanic crust.

Spreading rates determine if the ridge is fast intermediate or slow. Subduction and sea floor spreading are processes that could alter the size and form of the ocean. Sea floor spreading take place in mid ocean ridges. Davidjhills points 1356 log in for more information.

The rate at which new oceanic lithosphere is added to each tectonic plate on either side of a mid ocean ridge is the spreading half rate and is equal to half of the spreading rate. Seafloor bathymetry world war ii gave scientists the tools to find the mechanism for continental drift that had eluded wegener maps and other data gathered during the war allowed scientists to develop the seafloor spreading hypothesis this hypothesis traces oceanic crust from its origin at a mid ocean ridge to its destruction at a deep sea trench and is the mechanism for continental drift. Where does sea floor spreading take place. Spreading is generally thought of when speaking of sea floor spreading.
