Volcanic ash is a fine material produced during volcanic eruptions. It consists of tiny fragments of rock, minerals, and volcanic glass that are ejected into the atmosphere. When a volcano erupts, gases and magma are expelled, and as the magma breaks apart, it forms ash particles that can be carried by the wind over long distances. This ash can have significant effects on the environment and human activities. It can disrupt air travel, damage crops, and contaminate water supplies. Additionally, volcanic ash can pose health risks, particularly to the respiratory system, if inhaled in large quantities.
