Convection currents also recycle lithospheric materials back to the mantle.
Sea floor spreading science definition.
Mantle convection is the slow churning motion of earth s mantle.
Convection currents carry heat from the lower mantle and core to the lithosphere.
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.
Spreading rates determine if the ridge is fast intermediate or slow.
Spreading rate is the rate at which an ocean basin widens due to seafloor spreading.
Seafloor spreading theory that oceanic crust forms along submarine mountain zones and spreads out laterally away from them.
Seafloor spreading and other tectonic activity processes are the result of mantle convection.
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.
