Question

The description fits that of a stratovolcano, which commonly have steep sides, symmetrical shapes, layers of pyroclastic debris, and high-viscosity lava flows that form protective caps. Scoria cones, on the other hand, are smaller and have steep sides but are made of loose volcanic fragments. Shield volcanoes are wider with gentle slopes and are made of fluid basaltic lava flows. Calderas are large volcanic depressions that form after the eruption of a volcano.
