It is a center at the bottom of the ocean that occurs at mid-ocean ridges
Spreading centers.
Volcanoes at spreading centers is referred to as spreading center volcanism. This usually takes place on mid-oceanic ridges where the plates diverge.
At spreading centers.
These ridges are spreading centers or divergent plate boundaries
It is the mid-ocean ridges.

Both subduction zones and spreading centers.

Basaltic/mafic lava.
Near the trenches, or in the seafloor furthest away from spreading centers.
Spreading centers are geological formations where tectonic plates are moving away from each other, resulting in the upwelling of magma from the mantle and the formation of new oceanic crust. This process is known as seafloor spreading and occurs mainly along mid-ocean ridges, creating new oceanic crust and contributing to the Earth's tectonic activity.
