What main process do all volcanoes have in common, regardless of the specific ways they form?

Answer 1

The main process that all volcanoes have in common, regardless of the specific ways they form, is the movement of molten rock, known as magma, from within the Earth's interior to the Earth's surface. This movement of magma is facilitated by the presence of a conduit, called a volcanic vent or pipe, which connects the magma chamber beneath the surface to the surface itself. Once the magma reaches the surface, it is then called lava. This volcanic activity results in the extrusion of lava, gases, and other volcanic materials, forming the characteristic relief features and landscapes associated with volcanoes.
