Sea Floor Spreading Science Definition

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.

Sea floor spreading science definition.

Convection currents carry heat from the lower mantle and core to the lithosphere. Spreading rate is the rate at which an ocean basin widens due to seafloor spreading. 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. Seafloor spreading theory that oceanic crust forms along submarine mountain zones and spreads out laterally away from them.

Mantle convection is the slow churning motion of earth s mantle. Spreading rates determine if the ridge is fast intermediate or slow. 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.
