His boundless curiosity as well as his scientific and cultural knowledge helped lay the foundations of physical geography, climatology, ecology and oceanography. In 1799, Humboldt embarked on a five-year trip to explore Central and South America. He devoted a large amount of time to the study of g?ognosie, the science of the origin and distribution of minerals and rocks forming the earth, later known as geology. In 1805, Humboldt published his first impressions of volcanoes and earthquakes in the Americas in his Personal Narrative. In this 1826 work, he makes the first systematic attempt to compare the rocks of the Old and New Worlds. This groundbreaking analysis became one of the most important geological works of its time.Preface; Essai g?ognostique sur le gisement des roches dans les deux h?misph?res; Tableau des formations.
