Harry Hess was an American geologist and a key figure in the development of the theory of plate tectonics, which expanded upon Alfred Wegener's earlier concept of continental drift. In the early 1960s, Hess proposed the idea of seafloor spreading, suggesting that new oceanic crust forms at mid-ocean ridges and pushes tectonic plates apart. This process provided a mechanism for continental drift, demonstrating how continents could move over geological time. His work helped to solidify the understanding of the dynamic nature of Earth's surface and the movement of its plates.
What else can I help you with?
Is it true that Harry Hess introduced the theory of continental drift?
yes
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.
How are Alfred Wegener and Harry Hess similar?
they both were associated with plate boundaries and continental drift. Harry Hess's theory proved Alfred's to be true.
Which scientist's work provided evidence of moving continents making the continental drift theory accepted by the scientific community?
Alfred Wegener's work on continental drift and his publication of the theory in 1912 provided the initial framework for the idea. However, it was further developed and supported by scientists such as Harry Hess, who introduced the concept of seafloor spreading in the 1960s, leading to the acceptance of the theory of plate tectonics.
Explain Harry Hess contribution to Plate Tectonic Theory?
Harry 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.

What did Harry do?
Harry Hess suggested that continents do not move across the ocean crust. He made the theory of continental drift famous and somewhat accepted.
Who had the theory of sea floor spreading?
Harry Hess came up with the theory of seafloor spreading . Alfred Wegener came up with the idea of continental drift NOT sea-floor spreading.
Who had the sea floor spreading theory?
Harry Hess came up with the theory of seafloor spreading . Alfred Wegener came up with the idea of continental drift NOT sea-floor spreading.
How are Alfred Wegener and Harry Hess similar?
they both were associated with plate boundaries and continental drift. Harry Hess's theory proved Alfred's to be true.
What German scientist noted first proposed the theory of continental drift?
Alfred Wegener, a German meteorologist and geophysicist, first proposed the theory of continental drift in 1912. He suggested that the continents were once joined together in a single landmass called Pangaea and drifted apart over time.
Which scientist's work provided evidence of moving continents making the continental drift theory accepted by the scientific community?
Alfred Wegener's work on continental drift and his publication of the theory in 1912 provided the initial framework for the idea. However, it was further developed and supported by scientists such as Harry Hess, who introduced the concept of seafloor spreading in the 1960s, leading to the acceptance of the theory of plate tectonics.

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.
Who were the scientists that put this theory of plate tectonics together?
The theory of plate tectonics was developed by a combination of scientists, including Alfred Wegener, who proposed the idea of continental drift, and Harry Hess, who proposed the idea of seafloor spreading. Their work was later expanded upon by researchers like Fred Vine, Drummond Matthews, and J. Tuzo Wilson, leading to the development of the modern 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.
