Plate tectonics can lead to volcanic activity in two ways. Where two tectonics plates pull apart, the crust becomes thinner, which decreases pressure on the upper mantle and allows rock the melt and move to the surface. At subduction zones, where a plate collision forces oceanic crust into the mantle, seawater dragged down with the plate alters the chemistry of the mantle rock, allowing it to melt at a lower temperature.

because tectonic plates push together, and they don't have any where to go but up, so a volcano is formed! that is how mountains are formed also.
Volcanoes have been videoed under the oceans; volcanoes are associated with the joint between tectonic plates and many of these joints are in the deep ocean. It's been estimated that 75% of the magma in the world comes from submarine volcanoes.
tectonic plates colliding
When the tectonic plates cause earthquake, it creates a crater in earth. This opening can lead to a volcano.

Scientists observed that volcanoes and earthquakes occur at the edge of tectonic plates.
Volcanoes are only found on the edge of tectonic plates & they can also be found on cracks in the tectonic plates which is un-common
the tectonic plates shake under the earth causing earthquakes
Volcanoes usually form where tectonic plates meet.
On tectonic plates.
Over tectonic plates.
