What Is a volcano?

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.

How do volcanoes 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.

Are eruption styles important?

Eruption styles are important because different styles such as explosive eruptions can be very devastating to places around it and volcanic gasses form poisonous and invisible clouds in the atmosphere and can cause environmental problems such as acid rain. The eruption style can determine what type of volcano it is.
