Volcanoes: What They are and What They Teach

"Volcanoes: What They Are and What They Teach" by John W. Judd is a late nineteenth century publication that gives an overview of volcanoes and the ideas that explain how they act and the geologic rules that control them. It looks at the chemistry and physics behind eruptions and how volcanoes affect the Earth. The beginning of the book works to correct common misunderstandings about volcanoes, saying that they are more than "burning mountains." Judd focuses on scientific study and the history of volcano science and mentions people like Spallanzani and Poulett Scrope, who helped build current vulcanology. The text introduces the reader to different parts of what volcanoes do like when volcanoes let out steam and that gases interact, also how dynamic volcanoes like Stromboli and Vesuvius are which invites people to change how they think about volcanoes
