What else can I help you with?
What could wegener not satisfactorily explain about continental drift?
No
What was the problem with the theory of sea floor spreading?
The main problem with the theory of sea floor spreading was initially the lack of a known mechanism for how it could occur. Additionally, there was skepticism about the idea of continents moving because it challenged long-standing beliefs about the permanence of Earth's surface features. The theory faced criticism until the discovery of plate tectonics provided a mechanism to explain sea floor spreading and continental drift.
Why was the hypothesis of continental drift rejected when it was proposed by wegener?
Wegener's hypothesis of continental drift was rejected because he lacked a plausible mechanism to explain how the continents moved. Additionally, the scientific community at the time did not have sufficient evidence to support the idea of continents drifting. It wasn't until the theory of plate tectonics emerged later, providing a mechanism and supporting evidence, that continental drift became widely accepted.
What was the fatal weakness in wegeners theory?
One of the fatal weaknesses in Wegener's theory of continental drift was the lack of a plausible mechanism to explain how continents could move through the solid rock of Earth's mantle. Additionally, Wegener was unable to adequately explain what forces could be responsible for moving the 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 process helps explain how continents drifts?
Ocean-floor spreading.
What could wegener not satisfactorily explain about continental drift?
No
What was not used in support of the continental drift hypothesis?
One key piece of evidence that was not initially used in support of the continental drift hypothesis was a mechanism explaining how continents could move. It wasn't until the discovery of plate tectonics and the development of the theory of seafloor spreading that a mechanism was found to explain how continents drift.
How sea-floor spreading provides a way for continents to move Explain?
Sea-floor spreading is the process where new oceanic crust is formed at mid-ocean ridges, pushing the existing crust apart. As the crust spreads, it carries the continents on tectonic plates with it, causing the continents to move. This movement is called plate tectonics, and it is responsible for the shifting of continents over geological time scales.
What is seafloor spreading that ''helps'' the theory of continental drift?
How seafloor spreading helps to explain the theory of continental drift is that wegener couldn't explain why and waht force caused the continents to move and so seafloor spreading helps to explain the theory of continental drift because it shows the force that made the continents move and that was te only thing that wagener needed to prove his theory of continental drift............thanks
Think critically The ideas of Hess Wegener and others emphasize that earth is a dynamic planet. How is seafloor spreading different from continental drift?
Seafloor spreading refers to the process where new oceanic crust is created at mid-ocean ridges and spreads outward, pushing the continents apart. Continental drift, on the other hand, is the idea that the continents are slowly moving across the Earth's surface. Seafloor spreading is a mechanism that helps explain how continents drift apart as part of the larger theory of plate tectonics.
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.
Why were Wegener's ideas not immediately accepted by the scientific community?
Wegener's ideas of continental drift were not immediately accepted by the scientific community because he did not have a satisfactory explanation for the mechanism that could move continents. Additionally, his hypothesis was contrary to the prevailing scientific beliefs at the time, which focused on fixed continents and seafloor spreading. It wasn't until the development of the theory of plate tectonics in the 1960s that Wegener's ideas gained wider acceptance.
How does seafloor spreading explain continental drift?
Seafloor spreading is caused by two plates moving apart. This is caused by plate tectonics. Continental drift is also caused by plate tectonics. Therefore, we can conclude that continental drift is related to seafloor spreading. When the plates move, it carries the continents with it, and thus the continents drift away from each other.
What was the problem with the theory of sea floor spreading?
The main problem with the theory of sea floor spreading was initially the lack of a known mechanism for how it could occur. Additionally, there was skepticism about the idea of continents moving because it challenged long-standing beliefs about the permanence of Earth's surface features. The theory faced criticism until the discovery of plate tectonics provided a mechanism to explain sea floor spreading and continental drift.
Who were the two scientists who proposed the theory of seafloor spreading in the 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 was one of the objections to weighers theory?
One objection to Wegener's theory of continental drift was the lack of a detailed explanation for the mechanism driving the movement of continents. Critics argued that without a clear mechanism to explain how continents could move through solid rock, the theory was not scientifically sound.
