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 long was it before new evidence emerged to support wegeners theory of the continental drift?
New evidence supporting Alfred Wegener's theory of continental drift began to emerge in the late 1940s and early 1950s, approximately 30 years after he first proposed the theory in 1912. The development of plate tectonics, particularly the discovery of seafloor spreading and paleomagnetism, provided crucial evidence that validated Wegener's ideas. This shift in understanding revolutionized geosciences and established a comprehensive framework for explaining the movement of continents.
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 came up with the idea of seafloor spreading?
The idea of seafloor spreading was proposed by geologist Harry Hess in the early 1960s. He suggested that new oceanic crust is formed at mid-ocean ridges and that this crust moves away from the ridges, leading to the expansion of ocean basins. Hess's theory provided a mechanism for continental drift, which was originally proposed by Alfred Wegener. Together, these concepts helped lay the foundation for the modern theory of plate tectonics.
What two scientist proposed the theory of seafloor spreading in the early 1960s?
Alfred wegner

How did Alfred wegener's inventions helped us?
It helped us by creating the theory of seafloor spreading which is the proof alfred needed to complete his hypothesis
Why did other scientists not accept Alfred Wegeners theory?
why did other scientist not accpet Alfred Wegeners theory
Did Alfred wegeners have kids?
no
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.
What is Alfred Wegeners middle name?
Alfred Lothar Wegener
Who is Alfred wegeners mother?
Anna Wegener
What was Alfred wegeners hometown?
He was born in Berlin.
What is the name of Alfred wegeners super continent?
Alfred Wegener's supercontinent is called Pangaea.
Who were the two scientists who proposed the theory of seafloor spreading in early 1960s?
While two people proposed continental drift (Alfred Wegener and Alexander du Toit), it was just ONE scientist Harry Hess that proposed the mechanism of sea floor spreading to explain how the continents actually moved.
