SteveHarry Hess was a geologist who proposed the theory of seafloor spreading in the early 1960s. He suggested that oceanic crust is created at mid-ocean ridges, then moves away from these ridges, eventually getting subducted back into the mantle at deep-sea trenches. This concept laid the foundation for the development of the theory of plate tectonics.

Who proposed the theory of seafloor spreading based on maps of the ocean floor?
The theory of seafloor spreading was proposed by Harry Hess, a geologist and Navy officer, in the early 1960s. He proposed that new oceanic crust is formed at mid-ocean ridges and then spreads outward. This theory helped to explain the mechanism behind continental drift and plate tectonics.
Theory proposed by Harry Hess that includes processes along mid-ocean ridges?
The theory proposed by Harry Hess is called seafloor spreading. It suggests that new oceanic crust is formed at mid-ocean ridges through the upwelling of magma from the mantle, pushing older crust aside. This process contributes to the continuous movement of tectonic plates and plays a key role in the theory of plate tectonics.
Why did people believe Harry Hess and not believe Alfred Wegener?
Harry Hess proposed the theory of seafloor spreading, which provided physical evidence for the movement of the Earth's crust. Alfred Wegener proposed the theory of continental drift, which lacked a mechanism to explain how continents moved. Hess's theory had more scientific support and evidence, leading to greater acceptance by the scientific community.
Who was Harry Hess?
Harry Hess is a scientist who studied geology and he was born May 27, 1906 and died August 25, 1969 he was born in New York City and he discovered how the first layer of Earth (the crust) forms
Who was the first person to discover continental drift and tectonic plates?
Alfred Wegener, a German meteorologist, was the first person to propose the theory of continental drift in the early 20th century. The idea of tectonic plates was later developed and refined by scientists such as Harry Hess and Robert Dietz in the mid-20th century.
