Quizplus · Accepted Answer

When plates spread apart and magma rises, mid-ocean ridges form as new crust is created. This is the process of seafloor spreading, and it occurs at divergent plate boundaries. Mountains can form at convergent plate boundaries, where plates collide and are forced upwards, but this is not happening in the given scenario. Seas refer to bodies of water and do not directly form from plate tectonic activity. Subduction zones occur at convergent plate boundaries, where one plate is forced underneath another, and this also is not happening in the given scenario.
