3 What causes volcanoes?The blue lines represent the boundaries of the tectonic plates. The yellow area represents earthquake areas. The red area represents active volcanic action.The shifting of the tectonic plates causes pressure to build up underground. This pressure and friction from the movement of the plates causes heat to rise. The build up of heat and pressure needs an outlet. It finds the weakest land area (along the fault lines) and magma rises to the surface with explosive results.
