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.
Floor spreading definition.
Sea floor spreading synonyms sea floor spreading pronunciation sea floor spreading translation english dictionary definition of sea floor spreading.
That means the rock in the center is the youngest.
Spreading rates determine if the ridge is fast intermediate or slow.
Wherever the sea floor is spreading the edges move apart while the magma in the middle hardens.
Seafloor spreading definition is the divergence at mid ocean ridges of the tectonic plates underlying the oceans that is due to upwelling from the earth s interior of magma which solidifies and adds to the spreading plates.
The process of sea floor spreading.
Meaning pronunciation translations and examples.
The youngest crust of the ocean floor can be found near the seafloor spreading centers or mid ocean ridges as the plates split apart magma rises from below the earth s surface to fill in the empty void.
Seafloor spreading occurs along mid ocean ridges large mountain ranges rising from the ocean floor.
The mid ocean ridge is the region where new oceanic crust is created.
Ocean floor spreading definition.
The formation of the new crust is due to the rising of the molten material magma from the mantle by convection current.
Spreading rate is the rate at which an ocean basin widens due to seafloor spreading.
A series of processes in which new oceanic lithosphere is created at oceanic ridges.
As the continents move apart whole new oceans.
The oceanic crust is composed of rocks that move away from the ridge as new crust is being formed.
This spreading creates a successively younger ocean floor and the flow of material is thought to bring about the migration or drifting apart of the continents.
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.
