Which of the following volcanoes would you expect to erupt explosively : A volcano located near a subduction zone, or a volcano located on an island over a mantle hotspot? Explain your answer in terms of how the composition of the magma/lava impacts the physical properties (especially viscosity) of the magma, and how that would or would not lead to an explosive eruption. (7 points)

Iam pretty sure it is answer c. meep i hope you have a great day ^^

Mantle convection is the process that drives plate tectonics. the theory of plate tectonics states that the crust is divided into plates that float on the semi molten mantle below. the circular motion of the magma as it slowly rises and falls or move though convection cells drags the plates along causing them to move. the heat source in the lamp would represent the earth's core. the core is the source of energy that drives convection in the mantle. the lava represents molten magma under the earth's surface. if the lava lamp had floating pieces they would move as the circular motion of the lava in the lamp as it rises and falls would move them along the surface. these floating pieces would represent pieces of the earth's crust. 

Ithink the answer to that would be b):

A,f, g are the points
