Gas rich andesitic magmas generate composite cones made up of________ .
A) multiple overlapping rhyolite domes rimming a central caldera
B) conical shaped lava flows
C) abundant coarse pyroclastics and short, thick, viscous lava flows
D) abundant basalt dykes and thick accumulations of low viscosity flows

Question

Quizplus · Accepted Answer

Composite cones, or stratovolcanoes, are characterized by a combination of explosive activity and effusive lava flows, leading to the accumulation of coarse pyroclastic materials and short, thick, viscous lava flows typical of andesitic composition.
