Question

47. Which is one of the factors that control the shape and violence of volcanoes strength of roof over magma chamber type of opening (vent vs Tsure) Viscosity of Man d physical state of the magma e Actually, all of the above are factors

Answer 1

Answer:

all of the above are factors

Explanation:

• Factors that impact or control the movement of magma and lava from the volcanoes include a wide array of factors like the composition of magma and lava which is viscous fluid that brings up the intensity of violent eruptions of such as those that have higher silicate content.

• The explosion intensity also depends on the volume and length of the eruption and composition of volcanic products and their eruption environment.  

• The rooftop of the volcanoes i.e the upper chambers or vent is also seen as a major important factor controlling the opening of basaltic matter on the surface. In a shield volcano, the eruption matter is not that dense and vicious as compared to the Italian and strombolian volcano that have a high intensity of lava flows.
