Why do tectonic plates move to form volcano

On land, volcanoes form when one tectonic plate moves under another. Water trapped in the rocks in this plate gets squeezed out. This causes some rock to melt. The melted rock, or magma, is lighter than the surrounding rock and rises up.

Hope this helped.

When the tectonic plates try to walk to burger king, they always bump into each other because of how close together they are. Once in a while, a tectonic plate will get so pis sed of, it will form a volcano to let out its anger.
