What was Harry Hess's contribution to the plate tectonic theory?
Harry Hess significantly contributed to the plate tectonic theory through his research on ocean floor dynamics and the concept of seafloor spreading. In the early 1960s, he proposed that molten material from the Earth's mantle rises at mid-ocean ridges, creating new oceanic crust while older crust is pushed away. His ideas helped provide a mechanism for continental drift and supported the understanding that Earth's lithosphere is divided into tectonic plates that move over the asthenosphere. Hess's work laid crucial groundwork for the modern 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.
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.
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.
Which scientist is responsible for developing the plate tectonic theory?
The plate tectonic theory was developed through the contributions of several scientists, but key figures include Alfred Wegener, who proposed the idea of continental drift in the early 20th century, and Harry Hess, who introduced the concept of seafloor spreading in the 1960s. The theory was further refined by John Tuzo Wilson, who introduced the idea of transform faults. Together, their work laid the foundation for the modern understanding of plate tectonics.

Which was the theory of Harry Hess?
Harry Hess proposed the theory of seafloor spreading in the early 1960s, which explained how new oceanic crust forms at mid-ocean ridges and gradually moves away from these ridges. His work provided crucial support for the broader theory of plate tectonics, demonstrating that the Earth's lithosphere is divided into tectonic plates that interact at their boundaries. Hess's ideas helped to explain various geological phenomena, including earthquakes and the distribution of fossils and minerals.
Who named the tectonic plates tectonic and why?
harry hess named the tectonic plates but I'm not sure why =/
Why was Harry Hess important?
Harry Hess's discovery was important because it helped explain the theory of continental drift. His discovery, that on the sea floor magma pushes up which causes the plate tectonics to move which carries the continents with it, explains better reasoning to the theory. It also helped the scienctist to explain how the sea floor spreading is happening.

In 1960 harry hess proposed the theory of?
sea floor spreading. that the sea floor was spreading and there for pushing the continents .he continued studying Alfred Wegener's theory and became more knowledgeable about then started gathering information to prove the theory and did

What was harry Hess and contribution to the theory of continental Drift?
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.
Who is the proponent of tectonic plate?
The theory of plate tectonics was developed through the contributions of several scientists, but one of the key proponents is Alfred Wegener, who introduced the idea of continental drift in the early 20th century. His work laid the groundwork for the modern understanding of tectonic plates, which was further advanced by scientists like Harry Hess and Robert Dietz in the mid-20th century, leading to the comprehensive theory we have today.
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
