What Is a volcano?
A volcano is a mountain that forms from layers of lava and tephra. It was magma chambers below the Earths surface that flows through a conduit up to a vent which can clause eruptions. Gases, lava, and pyroclastic material are erupted from volcano vents.
How does a volcano work.
Magma is stored in chambers, during active periods it fills with magma. Then, the magma goes through a conduit into vents and when tectonic plates collide the magma goes up causing it to erupt.
What do volcanoes look like
Volcanoes have openings or vents, in the surface of Earth were gasses, lava and pyroclastic material are erupted. There are four types of volcanoes, Cinder cone, composite volcano, shield volcano, and a lava dome.
Where do they form?
Volcanoes form near hot spots spreading centers/fault zones, and subducted zones. A hot spot is a ball of magma underground that doesn't move even when plate move above them. Spreading centers/fault zones are places where tectonic plates are diverging. Subduction zones are when tectonic plates converge.
