Webvolcano diagrams In this topic, we look at how movements in the earth's crust can cause both volcanic eruptions and earthquakes. It also looks at different types of plate boundary and where volcanoes are located. WebVolcanoes often form along where plate tectonics make contact. The friction produced melts the Earth’s crust, creating magma. Extremely heated magma creates pressure and slowly rises to the surface through the fractures between the tectonic plates. Over time it finds its way out through a volcanic vent.
