Volcanic Ash: More Than Just A Science Project part of Cutting Edge:Geology and Human Health:Case Studies
The term "volcano" has its origin from the name of Vulcan, the Roman god of fire. However, volcanoes are a result of processes of the earth much older than Roman mythology. While volcanoes may be fun to construct for science class or watch on television, the real consequences of volcanic eruptions can be harmful and serious. Some of these consequences include fires, structure damage, and differences in climate. One of the most deadly effects of a volcano is the ash coming from the eruption, which carries poisonous gases that are harmful to humans, plants, and animals alike.
