Keywords for continental drift include plate tectonics, Alfred Wegener, Pangaea, geological, seismic activity, fossil evidence, oceanic ridges, paleomagnetism, and continental margins. These terms highlight the movement of Earth's lithospheric plates, the historical supercontinent theory, and the supporting evidence from various scientific disciplines. Understanding these concepts is essential for grasping the dynamics of Earth's surface and its geological history.
In 1960, the discovery of oceanic spreading at mid-ocean ridges provided crucial evidence supporting the theory of continental drift. The identification of symmetrical patterns of magnetic striping on either side of these ridges indicated that new oceanic crust was being formed and pushed outward, confirming that continents could drift apart as tectonic plates moved. This process of seafloor spreading was instrumental in corroborating Alfred Wegener's earlier hypothesis of continental drift.
The theory that states new land is added to continental margins at subduction zones is called the theory of plate tectonics. This process occurs when oceanic plates are subducted beneath continental plates, leading to the creation of volcanic arcs and land accretion along the continental margin.
The theory of continental is not accepted as it is been disproved, but it was replaced by the theory plate tectonics. This theory accepted because of may factors including the discovery of mid-ocean ridges, subduction zones, and the tracking of plates via GPS and other means.
Seafloor Spreading.
Scientists use evidence such as matching fossil records, rock formations, and geological structures across continents, as well as the fit of the continents themselves, to support the theory of continental drift. Additionally, studies of oceanic crust age and magnetic patterns on the seafloor provide further evidence for plate tectonics and continental movement.
The Continental Drift theory is a theory because there is no evidence to support it. Alfred Wegener developed the Continental Drift theory in the 1800's.
Continental Drift is an obsolete name for the theory of Plate Tectonics and yes, it is true. It has been proved in many ways, by comparing the composition of oceanic crust and its ages with that of the continental crust, by plotting the reversals of magnetism in the oceanic crust and many other ways.
The theory of continental drift has been well-supported by evidence from various fields such as paleontology, geology, and paleoclimatology. To disprove it, one would need to provide strong evidence that contradicts the observed patterns of continental fit, matching geological formations across continents, distribution of fossils, and other supporting data. However, to date, no such evidence exists to conclusively disprove the theory of continental drift.
Cell Theory
The theory of plate tectonics has succumbed to the newer theory of continental drift. Scientists believe this theory today due to three main factors. First, the continents appear to fit together. When the continental shelves, as opposed to just the continents, are placed together, the fit appears uncanny. Second, the distribution of fossils is consistent with continental drift. Lastly, glacial deposits once covered parts of the earth that are currently tropical.ANSWER: The plate tectonics theory is relatively new and formulated only in the 1960s. The evidence listed above in the first answer can only support the continental drift theory which was developed by Alfred Wegener in 1912. Evidence that can support the plate tectonics theory are the age, depth of oceanic sediments, volcanic activity, geothermal gradient, gravity anomalies, paleomagnetism and seismologic evidence. If you are answering an exam question on evidence supporting plate tectonics, evidence supporting continental drift theory should only come later in your answer and should not be given too much emphasis, for the plate tectonics theory involves more than just the continental crust drifting around and cannot support the main hypotheses of the plate tectonics theory.
Alfred Wegener was a scientist who proposed the theory of continental drift and the idea of isostasy. The idea of isostasy stated that continental blocks drifted upon oceanic blocks (continental blocks had a lower density than oceanic blocks, which explained why it was higher than oceanic blocks).
Yes, seafloor spreading provided concrete evidence for the theory of continental drift proposed by Alfred Wegener. It demonstrated that new oceanic crust was continuously forming at mid-ocean ridges, pushing the continents apart over time. This supported the idea that continents were once connected and have since moved to their current positions.
the theory of sea floor spreading or continental drift
Scientist rejected Wegners hypothesis of continental drift at first because he did not have enogh evidence to support his theory. He failed to provide a suitable mechanism that could cause the continents to move.

continental drift. This is because the presence of similar fossils on opposite sides of the ocean suggests that the landmasses were once connected and have since drifted apart. This phenomenon supports the theory of continental drift proposed by Alfred Wegener.
