plates move by the convectional currents in the magma below the earths crust, and so they move the plates. the earths crust is split up into plates and when the convectional current moves them, they can collide. when they collide, they make the plate thinner on that area and this allows the molten to come through. each time the volcanoe erupts, the volcanoe gets bigger and bigger as more layers of molton rock are composited on to the volcanoe.
The presence of large, rigid plates on the planet's surface that move and interact with each other, causing earthquakes and volcanic activity, is the best indication that the planet may have plate tectonics. Additionally, features like mountain ranges, deep ocean trenches, and mid-ocean ridges suggest the presence of plate tectonics.
mid-ocean ridges and volcanoes
No, most of the volcanoes along the mid-ocean ridge do not rise above the ocean's surface. These submarine volcanoes are typically under the water and form part of the continuous volcanic activity that occurs along the ocean ridges. Only a few volcanoes along the mid-ocean ridge, such as Iceland, rise above the ocean's surface.
The discovery of ocean floor spreading provided evidence for plate tectonics theory, showing that the Earth's crust is continuously moving and renewing itself. It revolutionized our understanding of Earth's geology and helped explain phenomena like earthquakes, volcanoes, and mountain formation.

Chains of volcanos along ocean Coastlines
The Pacific Ocean has a ring of volcanoes known as the Ring of Fire. This area is located in the Pacific Ocean basin and is characterized by frequent earthquakes and volcanic activity due to plate tectonics.

The theory of plate tectonics is supported by evidence such as the matching coastlines of continents, distribution of earthquakes and volcanoes along plate boundaries, and the mapping of magnetic striping on the ocean floor. Additionally, studies of mid-ocean ridges and subduction zones provide further evidence for the movement of Earth's lithospheric plates.
The plate tectonics explains the locations of volcanoes. Each continent sits on one or more large bases tectonic plates. As the plates move, the continents atop them move, an effect called continental drift.
