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.
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.
What is the importance of the discovery of deep-sea drilling in understanding the current theory of plate tectonics?
The discovery of deep-sea drilling is important in understanding plate tectonics because it provides direct evidence of the movement of Earth's tectonic plates. By studying the rock samples obtained from deep-sea drilling, scientists can analyze the age and composition of the oceanic crust, which supports the theory of plate tectonics and helps explain how the Earth's surface is constantly changing and evolving.
How does seafloor spreading help to explain continental drift?
Seafloor spreading provides evidence for the theory of continental drift by showing that new oceanic crust is continuously formed at mid-ocean ridges and spreads outward, pushing the continents away from each other. This process accounts for the movement of the continents over time and helps explain how separate landmasses once formed a single supercontinent called Pangaea.
Explain how ocean-floor rocks and sediments are evidence of seafloor spreading?
Ocean-floor rocks and sediments show a pattern of symmetric age distribution, with younger rocks near mid-ocean ridges and older rocks farther away. This supports the theory of seafloor spreading, where new oceanic crust is created at mid-ocean ridges and spreads away from them. As the crust moves, it picks up and records the magnetic signature of Earth's magnetic field, creating alternating magnetic stripes that are evidence of seafloor spreading.
What was the effect of scientists' discovery of ocean floor spreading?
The discovery of ocean floor spreading provided evidence for plate tectonics theory, showing that the Earth's crust is continuously moving and renewing itself. It revolutionized our understanding of Earth's geology and helped explain phenomena like earthquakes, volcanoes, and mountain formation.
What was the effect of scientists discovery of ocean floor spreading?
The discovery of ocean floor spreading provided key evidence for the theory of plate tectonics, explaining how the Earth's lithosphere is broken into plates that move over the asthenosphere. This discovery revolutionized our understanding of the Earth's geology and helped explain processes like continental drift, earthquakes, and volcanic activity.
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.

How did the seafloor spreading help prove the continental drift?
Seafloor spreading provided evidence for continental drift by showing that new oceanic crust is formed at mid-ocean ridges, pushing older crust away. This process helped explain how continents could move and supported the idea of plate tectonics. The pattern of magnetic stripes on the seafloor also matched with predictions based on the movement of continents, further supporting the theory of continental drift.
What process helps explain how continents drifts?
Ocean-floor spreading.
A technique for helping with pronunciation is 3 by 3 drilling Explain this technique?
Three by three drilling is when one dude drills three chicks at once. First backward, then forward. Hence the name, three (backward) by three (forward) drilling.
