How is the formation of a composite cone different from a hot spot volcano?

Answer 1

That's a very good question.

Answer 2

A composite cone is formed over a subduction zone where oceanic crust sinks beneath continental crust, leading to explosive eruptions and the build-up of layers of lava and ash. In contrast, a hot spot volcano forms over a stationary magma source in the mantle, creating a shield volcano with a gentle slope from the eruption of low viscosity lava.
