Answers. Best Answer: Volcanoes form when hot material from below rises and leaks into the crust. The hot material, called magma, rising from lower ground, gathers in a reservoir called the magma chamber.Eventually, but not always, the magma erupts onto the surface and forms lava. volcano is formed when plates hit each other.
