The term VOLCANIC PARTICLE can be summarized as a three-letter word, ASH. Volcanic ASH is a type of pyroclastic material that is created when a volcano erupts. It is made up of tiny particles of rock and glass that are blasted into the air by the force of the eruption. The ASH is then carried away by the wind and can travel for hundreds or even thousands of miles. Volcanic ASH can cause damage to buildings, crops, and other structures, and can also affect air quality.
