Best Answer

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.
