How do volcanoes form at conservative plate boundaries?

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. WebVolcanoes erupt because of the way heat moves beneath Earth ’s surface. Heat is conveyed from the planet’s interior to its surface largely by convection —the transfer of heat by movement of a heated fluid. In this case, the fluid is magma —molten or partially … WebOn Earth, volcanoes are most often found where tectonic plates are diverging or converging, and most are found underwater.
