Which of the following tectonic settings has the greatest range in magma compositions?
A)convergent plate boundaries
B)transform plate boundaries
C)divergent plate boundaries
D)hot spots (mantle plumes)

Question

Quizplus · Accepted Answer

Convergent plate boundaries have the greatest range in magma compositions because they involve the subduction of oceanic crust beneath continental or oceanic crust. This process leads to the melting of the subducted plate and the overlying mantle, producing magmas that can range from basaltic to andesitic to rhyolitic in composition.
