The geographical feature that can consist of vents, side pipes, and a magma chamber is a "volcano". A volcano is a rupture in the Earth's crust that allows hot lava, ash, and gases to escape from a magma chamber beneath the surface. The vents and side pipes are openings in the volcano that allow the magma to flow to the surface, while the magma chamber is the reservoir of molten rock beneath the volcano. Volcanoes can be found all over the world and can be very dangerous, but they also play an important role in shaping the Earth's surface and providing nutrients for plant growth.
