How does a subduction zone cause a volcanoe to erupt?

Question

need full details!!!

thanks you very muych

Answer 1

what happens at a subduction zone is that the dense plate gets pulled under the less dense plate. as the subducting plate moves closer to the core, it melts and rises as magma. it comes out through the weak spots in the plate, over time it build to form a volcano. the rising magma builds pressure inside the volcano and eventually it erupts.

i hope that detailed enough for u.
