Steam and gas cannot pile up. Stratovolcanoes are composed of piles of volcanic ash ("dust") and lava flows. Cinder cones are composed of piles of rock fragments. Shield volcanoes are composed of layers of lava flows.

How could you treat gold dust and turn it into gold coins?

Gold dust, when in bulk, can be treated and turned into gold coins with heat. The dust will melt creating one uniformed liquid form that can be easily casted into coins by using molds then immediately cooled to harden the gold.

Why does dust come out of a volcano after it erupts?

During a volcanic eruption, the intense heat and pressure inside the volcano causes rocks to melt and turn into magma. When this magma reaches the Earth's surface, it cools rapidly and solidifies into tiny rock fragments and ash, which is what we see as dust coming out of the volcano.

How do felsic lavas cool to form igneous rocks?

Felsic lavas cool to form igneous rocks when they solidify and harden after being erupted from a volcano. The cooling process can happen either on the surface of the Earth or underground, and the slow cooling allows minerals to crystallize and form the igneous rock.
