What kind(s)of lava are most closely associated with composite cones?

Question

Quizplus · Accepted Answer

Composite cones, also known as stratovolcanoes, are typically made up of layers of andesitic lava flows and pyroclastic deposits. Andesitic lava has intermediate viscosity and erupts explosively, leading to the formation of the steep slopes and characteristic cone shape of composite cones. Rhyolitic lava is too viscous to flow far from the vent, while basaltic lava is too fluid to build up into steep cones.
