The Magma Chamber - The magma chamber sits at the base of the volcano, its in a 3D circular shape, its role it to recieve magma from the plume and feed it to the conduits running through the volcano. Think of it as the fuel tank of the volcano.
Conduits - Conduits are usually tens of metres in diameter. They link the shallowest magma chamber to the surface of the volcano and a vent is formed. Conduits can sometimes relocate which results in overlapping craters. Sometimes conduits have side branches leading off them to flanks of a volcano that can form secondary vents.
Lava – Lava is the molten rock that oozes out from a volcano's crater during an eruption. When it first comes out, the lava can have a temperature higher than 700 degrees C. It then flows downhill from the eruption point until it cools and eventually hardens.
Main Vent – A volcano’s main vent is the point in the Earth’s crust where hot magma has reached the surface. The volcano builds up as ash, rock and lava ejected during eruptions fall back to Earth around the vent
Flanks- The sides of a volcano, close to the crater where from the lava erupts from and slides down and across. Usually built up in layers because of the constant cooling and melting of the lava flow that builds up over time.
subduction volcano- when one techtonic plate is forced under another one and pushed down towars the mantle and the futher down it goes it melts and turns into molten rock
Crater- a volcano crater is a circular depression around a volcanic vent. This is where the lava, ash and rock erupt out of a volcano. In most volcanoes the crater is located at the top of the volcano.
what a volcano is. A volcano is any opening in the Earth's surface which can allow molten rock and volcanic gases to escape from far below the Earth's surface.
bedding/strata - these are the layersof volcanic rock that sets to form the flanks of the volcano. the strata can sometimes be steep and may also be shallow due to the different viscousity.

the plume where magma travells up into the magma champer from the uppermantle, which then goes through the conduit and errupts at the surface

A magma chamber is a large reservoir in the crust of the earth that is occupied by a body of magma

Parasitic Cone- is a cone shaped build up of volcanic material made by eruptions from fractures other that the central vent of the volcanoe.
