they both were associated with plate boundaries and continental drift. Harry Hess's theory proved Alfred's to be true.

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.
What scientist used sonar to prove seafloor spreading under the Atlantic ocean?
Harry Hess, an American geologist and Navy officer, used sonar to study the seafloor of the Atlantic Ocean. He discovered the presence of mid-ocean ridges and proposed the theory of seafloor spreading in the early 1960s, which played a crucial role in the development 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 thought of plate tectonics theory?
The theory of plate tectonics was developed through the contributions of several scientists, including Alfred Wegener, who proposed the theory of continental drift in the early 20th century. Later research by Harry Hess and Robert Dietz provided evidence for seafloor spreading, leading to the development of the modern plate tectonics theory in the 1960s.
How old was Harry Hess when Alfred Wegner died?
Harry Hess was born on May 24th, 1906. Alfred Wegener died sometime in November of 1930. That would mean that Harry Hess was about 24 years old when Wegener died.
How old was harry hess when wegener died?
Alfred Wegener died in November 1930. Harry Hess was born on May 24th, 1906. That would mean that Harry was 24 when Wegener died.

How are Harry Hess's and Alfred Wegener's hypothesises similar?
Both Harry Hess and Alfred Wegener proposed groundbreaking theories related to the movement of Earth's crust. Wegener's hypothesis of continental drift suggested that continents were once connected and have since moved to their current positions, while Hess's hypothesis of seafloor spreading explained how new oceanic crust forms at mid-ocean ridges and pushes older crust away. Both hypotheses contributed to the development of the theory of plate tectonics, which revolutionized our understanding of the Earth's dynamic processes.

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.

When did harry hess propose seafloor spreading?
Harry Hess proposed the idea of seafloor spreading in the early 1960s, with his initial proposal being presented in 1960. This concept revolutionized our understanding of plate tectonics and the movement of the Earth's lithosphere.
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.
