I became aware of this title during the October 5th episode of Star Talk Radio podcast, Space Volcanoes with the author as guest. Now, I have read about volcanoes before, but only about their destruction in Indonesia and South America. Fire & Ice by Natalie Starkey delves into volcanoes and volcanic activity on Earth and in outer space! The author, Natalie Starkey, explains the science that links volcanoes and their activity to the picture of the inner workings of planets. The internal heat of a planet and its volcanism is the key to hosting life. The ways a volcano erupts and the composition of its erupting product, can help scientists determine the possibility of the presence of life.
