Ответ:
different chemicals in an erupting volcano's magma affects the temperature, which in turn affects the viscosity, which affects the eruption itself
for example, less silica content in the magma means lower temperature which means the lava cools down faster and hardens faster, which means the viscosity increases, which in turn results in relatively quiet explosion.
