Key process at plate margins #1: Seafloor spreading at midocean ridges. Where seafloor spreading takes place - Midocean ridges. Seafloor spreading. Version 27 Oct 2015 Plate Tectonics: Seafloor Spreading. Labels. Transfrom Fault. Fracture Zone. Midocean Ridge. Subsurface Features. 5 cm per year. 10 k yrs. 1 k yrs. 1 M yrs. The essential processes of plate tectonics are 1)seafloor spreading and 2) subduction. These two processes operate on basic units called plates. Key surface Magnetization of the Sea Floor and Seafloor Spreading Seafloor spreading is one of the two major processes of plate tectonics, the other being subduction.
