Harry H. Hess

Harry H. Hess was a geologist and geophysicist known for his groundbreaking work in understanding Earth's surface. He proposed the theory of seafloor spreading, which explains how new oceanic crust forms at mid-ocean ridges and moves outward, causing continents to drift. This idea supported the broader theory of plate tectonics, transforming our understanding of Earth's geology and the movement of continents over millions of years. His research provided crucial evidence for the dynamic nature of Earth's crust, helping scientists comprehend the processes behind earthquakes, mountain formation, and volcanic activity.
