Volcanoes are usually formed by the pressure of the tectonic plates beneath them. They push against one another and are pushed in an upward motion by the lava streams or pools below them.
Continental volcanoes are formed through the movement of tectonic plates, particularly at convergent and divergent boundaries, where magma generation occurs. Rising magma can lead to eruptions as pressure builds, creating these volcanoes mainly found near active plate interactions. A notable example is the Cascade Range in the Pacific Northwest, shaped by tectonic dynamics.
