Theory of seafloor spreading description.

Seafloor spreading was proposed by an american geophysicist harry h. At ridges in the middle of oceans new oceanic crust is created. 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. When oceanic plates diverge tensional stress causes fractures to occur in the lithosphere.

N a series of processes in which new oceanic lithosphere is created at oceanic ridges spreads away from the ridges and returns to the earth s interior. As upwelling of magma continues the plates continue to diverge a process known as seafloor spreading samples collected from the ocean floor show that the age of oceanic crust increases with distance from the spreading centre important evidence in favour of this process. Convection currents also recycle lithospheric materials back to the mantle. Seafloor spreading happens at the bottom of an ocean as tectonic plates move apart.

The seafloor moves and carries continents with it. First proposed in the early 1960s by the american geologist harry h. 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. Mantle convection is the slow churning motion of earth s mantle.

Convection currents carry heat from the lower mantle and core to the lithosphere. The theory of seafloor spreading the mid ocean ridge is where the seafloor spreading occurs in which tectonic plates large slabs of earth s lithosphere split apart from each other. Seafloor spreading theory of lithospheric evolution that holds that the ocean floors are spreading outward from vast underwater ridges. Seafloor spreading helps to explain continental drift in the theory of plate tectonics.

These age data also allow the rate of seafloor spreading to be determined and they show that rates. The motivating force for seafloor spreading ridges is tectonic plate slab pull at subduction zones rather than magma pressure although there is typically. The motivating force for seafloor spreading ridges is tectonic plate pull rather than magma pressure although there is typically significant magma activity at spreading ridges. Seafloor spreading and other tectonic activity processes are the result of mantle convection.
