| Title: | Seafloor Spreading and Plate Boundaries. |
| Caption: | This animation depicts a 100,000-year time span of seafloor spreading. It details the upwelling of magma at a midocean ridge along with associated transform faults. It also shows the subduction of oceanic crust under continental crust and the resulting formation of magma and subsequent volcanism. |
