Seamounts are isolated volcanic mountains scatteredacross the ocean floor
A circular basin surrounded by mountains is typically referred to as a crater or caldera, depending on whether it was formed by volcanic activity or by the collapse of a volcanic cone.
Ocean basin shrinking at convergent boundaries occurs when two tectonic plates collide, leading to subduction of the denser oceanic plate beneath the less dense continental plate. This process results in the closure of the ocean basin and the formation of mountain ranges or volcanic arcs along the convergent boundary. An example of this is the Andes Mountains in South America, where the Nazca Plate is subducting beneath the South American Plate, causing the ocean basin to shrink and the mountains to rise.
