Ash (volcanic)

Volcanic ash consists of tiny particles and fragments of rock and glass ejected during a volcanic eruption. It is formed when magma explosively breaks apart as it reaches the surface, creating a fine, powdery material that can travel great distances with the wind. Ash can affect air travel, cause health issues, and damage machinery or buildings. It typically falls to the ground within hours to days of an eruption and varies in color from grey to black, sometimes with a reddish hue due to mineral content. While often destructive, volcanic ash also plays a role in enriching soils over time.
