Draft:Outline of volcanoes

The following outline is provided as an overview of and topical guide to volcanoes:

A volcano is a rupture in the crust of a planetary-mass object, such as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface. The process that forms volcanoes is called volcanism.

Below is a structured list of topics related to volcanos:

What type of things are volcanoes?

Volcanoes can be described as all of the following:

Landform – natural feature of the solid surface of the Earth or other planetary body. Landforms together make up a given terrain, and their arrangement in the landscape is known as topography. Typical landforms include hills, mountains, plateaus, canyons, valleys, as well as shoreline features such as bays, peninsulas, and seas, including submerged features such as mid-ocean ridges, volcanoes, and the great ocean basins.

Types of volcanoes

Caldera – Cauldron-like volcanic feature formed by the emptying of a magma chamber
Cinder cone – Steep hill of pyroclastic fragments around a volcanic vent
Complex volcano – Landform of more than one related volcanic centre
Cryovolcano – Type of volcano that erupts volatiles such as water, ammonia or methane, instead of molten rock
Cryptovolcanic structure – Type of crater
Fissure vent – Linear volcanic vent through which lava erupts
Lava dome – Roughly circular protrusion from slowly extruded viscous volcanic lava
Maar – Low-relief volcanic crater
Mud volcano – Landform created by the eruption of mud or slurries, water and gases
Parasitic cone – Geological feature associated with some volcanos
Pyroclastic cone – Landform of ejecta from a volcanic vent piled up in a conical shape
Pyroclastic shield – Shield volcano formed mostly of pyroclastic and highly explosive eruptions
Rootless cone – Volcanic landform
Shield volcano – Low-profile volcano usually formed almost entirely of fluid lava flows
Somma volcano – Volcanic caldera that has been partially filled by a new central cone
Stratovolcano – Type of conical volcano composed of layers of lava and tephra
Subglacial volcano – Volcanic form
Submarine volcano – Underwater vents or fissures in the Earth's surface from which magma can erupt
Supervolcano – Volcano that has had an eruption with a volcanic explosivity index (VEI) of 8
Volcanic cone – Landform of ejecta from a volcanic vent piled up in a conical shape
