Wegeners hypothesis of continental drift was replaced in 1967 by which theory that supported his idea continents move?
plate tectonics
What else can I help you with?
What was the reason wegeners continental drift hypothesis was rejected?
His evidence was incorrect.
What kind of fossil evidence supported wegeners hypothesis?
Fossil evidence supporting Wegener's hypothesis of continental drift included identical fossils found on separate continents, showing that these landmasses were once connected. This supported the idea that continents had drifted apart over time. Additionally, the presence of ancient glacial deposits in regions that are now too warm for glaciers to form suggested that these areas were once located closer to the South Pole.
How did the discovery of Glossopteris support Wegeners continental drift hypothesis?
Because identical fossils were found on two continents far apart, it suggested that at one time the two landmasses were joined together. In other cases of lands separated by far less distance, plants did not propagate across the divide.
Wegeners hypothesis of continental drift was finally confirmed by?
evidence supporting the idea of sea-floor spreading.
Which observation supported Wegeners theory of continental drift?
The fit of the continents like pieces of a puzzle, similarities in rock formations and fossil records across continents, and the matching geological structures on opposite sides of the Atlantic Ocean all supported Wegener's theory of continental drift.
What was the main reason wegeners continental drift was rejected?
He could not provide a wholly acceptable explanation for the movement of the continents.
What is wegeners hypothesis for continental drift?
Wegener's hypothesis for continental drift, proposed in the early 20th century, suggests that continents were once part of a single supercontinent called Pangaea, which gradually broke apart and drifted to their current positions. He based his hypothesis on evidence such as the fit of continental coastlines, similar geological features across continents, and fossil correlations. Despite presenting compelling evidence, Wegener's theory was initially met with skepticism due to the lack of a mechanism to explain how continents could move. It wasn't until the development of the theory of plate tectonics that his ideas gained widespread acceptance.
Give an example of evidence from land features that supported wegeners idea of continental drift?
An example of evidence from land features that supported Wegener's idea of continental drift might include the piecing together of map layouts which show the way that the continents fit together. Wegener is famous for sharing this example.
What were the flaws in wegeners hypothesis that made people reject it?
Wegener's hypothesis of continental drift was largely rejected due to a lack of a plausible mechanism to explain how continents could move across the Earth's surface. He proposed that continents plowed through the oceanic crust, which seemed implausible to many scientists. Additionally, his ideas conflicted with the prevailing theories of the time, such as land bridges and static continents. The discovery of plate tectonics in the 1960s eventually provided the necessary mechanisms for continental movement, validating Wegener's ideas long after their initial rejection.
What was an important reason why wegeners continental drift hypothesis was widely accepted?
The continental Coastlines fit together like puzzle pieces, fossils, and glacier Grover in warm places
What supported wegeners idea of continetal drift?
Key pieces of evidence supporting Wegener's idea of continental drift include the jigsaw fit of continental coastlines (e.g., South America and Africa), matching geological formations on different continents, and similarities in plant and animal fossils found across continents separated by oceans. Additionally, the discovery of mid-ocean ridges and the mapping of Earth's magnetic field reversal patterns supported the theory of plate tectonics.
How did discovery of glossopteris support Wegeners continental drift hypothesis?
Because identical fossils were found on two continents far apart, it suggested that at one time the two landmasses were joined together. In other cases of lands separated by far less distance, plants did not propagate across the divide.
