Seafloor spreading is a geologic process in which tectonic plates large slabs of earth s lithosphere split apart from each other.
Sea floor spreading earth science definition.
The solid surface underlying a sea or an ocean.
Seafloor spreading and other tectonic activity processes are the result of mantle convection.
Geological science 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 along subduction zones.
Seafloor spreading is a process that occurs at mid ocean ridges where new oceanic crust is formed through volcanic activity and then gradually moves away from the ridge.
