The volcanic landforms at divergent ocean plate boundaries are _oceanic ridges____.
Explanation:
As two tectonic plates move away from each, they leave a vacuum in between the two plates. This vacuum is filled by upwelling magma from the mantle. As the upwelling magma cools it forms a mountainous ridge along the boundary – because the magma cools rapidly before it could spread further out on the surface. Examples of these landforms are the Mid-Atlantic Ridge and the East Pacific Rise located at divergent tectonic boundaries.
Explanation:It is moving WSW at 2.2 cm (0.87 in)/year and the South Sandwich Plate is moving east at 5.5 cm (2.2 in)/year in an absolute reference frame. The Scotia Plate is made of oceanic crust and continental fragments now distributed around the Scotia Sea.
