Jan Zalasiewicz, profesor de paleobiología en la Universidad de Leicester, profundiza en el Antropoceno.
Jan Zalasiewicz es profesor de paleobiología en la Universidad de Leicester, Reino Unido. Al principio de su carrera, fue geólogo de campo y paleontólogo en el Servicio Geológico Británico, trabajando para descifrar los estratos del este de Inglaterra y luego las montañas del centro de Gales. Ahora, enseña geología e historia de la Tierra a estudiantes de pregrado y posgrado, y estudia ecosistemas y entornos fósiles a lo largo de más de quinientos millones de años de tiempo geológico. En los últimos años, ha estado involucrado en ayudar a desarrollar ideas sobre el Antropoceno, el concepto de que los humanos ahora impulsan gran parte de la geología en la superficie de la Tierra, y preside el Grupo de Trabajo de Antropoceno de la Comisión Internacional de Estratigrafía.
Volcanoes (A very short Introduction) pdf por Jan Zalasiewicz
Volcanoes are some of the most dramatic expressions of the powerful tectonic forces at work in the Earth beneath our feet. But volcanism, a profoundly important feature of Earth, and indeed of other planets and moons too, encompasses much more than just volcanoes themselves. On a planetary
scale, volcanism is an indispensable heat release mechanism, which on Earth allows the conditions for life. IIt releases gases into the atmosphere and produces enormous volumes of rock, and spectacular landscapes - landscapes which, during major eruptions, can be completely reshaped in a matter of
hours. Through geological time volcanism has shaped both climate and biological evolution, and volcanoes can affect human life, too, for both good and ill. Yet, even after much study, some of the fundamental aspects of volcanicity remain mysterious.
This Very Short Introduction takes the readers into the inferno of a racing pyroclastic current, and the heart of a moving lava flow, as understood through the latest scientific research. Exploring how volcanologists forensically decipher how volcanoes work, Michael Branney and Jan Zalasiewicz
explain what we do (and don't) understood about the fundamental mechanisms of volcanism, and consider how volcanoes interact with other physical processes on the Earth, with life, and with human society.
