How is volcanic ash made? | HowStuffWorks
In the case of volcanoes, escaping gases carry magma up into the air. The sheer violence of the explosion shreds the rising magma into tiny particles -- much like how a sneeze emits moisture in tiny droplets. These minuscule pieces of magma then solidify in the air, becoming volcanic ash. We call flowing surface magma lava.
