How volcanism occurs
WebHow are volcanoes and earthquakes interrelated? Both volcanoes and earthquakes occur due to movement of the Earth’s tectonic plates. They are both caused by the heat and energy releasing from the Earth’s core. … WebVolcanic activity frequently occurs at the boundaries of the Earth's tectonic plates. The movement of these plates plays a significant role in the type of volcano formed, which influences its shape. Spreading plate margins. Areas of the Earth where plates move away from each other are called spreading or divergent plate margins.

WebVolcanoes occur most often along plate boundaries. Convergent plate boundaries where oceanic crust is subducted form many of the volcanoes found on Earth. Divergent plate boundaries produce huge mountain ranges under water in every ocean basin. Volcanoes like those that form the islands of Hawaii, form over areas called hot spots.
