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.

What discovery caused scientists to rethink wegeners continental drift theory?
The discovery of mid-ocean ridges and the process of seafloor spreading in the 1960s caused scientists to rethink Wegener's theory of continental drift. This new evidence provided a mechanism for how continents could move apart and lent support to the concept of plate tectonics as the driving force behind the movement of Earth's lithospheric plates.
How did the discovery of coal deposits in England and Antarctica strengthen Wegeners argument?
The discovery of coal deposits in both England and Antarctica supported Wegener's theory of continental drift by providing evidence that these regions were once connected in a single landmass, known as Pangaea. The presence of similar coal deposits across these distant locations suggested that they were once part of the same continent and had drifted apart over time.
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.
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.
What are 2 pieces of evidence that support alfreds wegeners theory of continental drift?
Fossil evidence: the discovery of identical fossils on continents separated by vast oceans supports the idea that these landmasses were once joined together. Matching geological features: the alignment of mountain ranges and rock formations on different continents, such as the Appalachian Mountains in North America and the Caledonian Mountains in Europe, provide evidence of past connections.
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.
What was the reason wegeners continental drift hypothesis was rejected?
His evidence was incorrect.
What discovery led scientists to accept Wegeners continental drift hypothesis?
One day while scientists were exploring the sea floor, they discovered sea-floor spreading, thus proving Wegener's hypothesis to be correct.
Wegeners hypothesis of continental drift was finally confirmed by?
evidence supporting the idea of sea-floor spreading.
Wegeners hypothesis of continental drift was replaced in 1967 by which theory that supported his idea continents move?
plate tectonics
What evidence did Wegeners have to support his theory?
Fossils support his hypothesis.
Why is Alfred wegeners invention or discovery important to science?
because it just is
Does the case of mesosaurus support wegeners theory of continental drift?
yes it does.
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.
Why was wegeners idea denied?
The scientific means for proving his hypothesis had not yet been developed.
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 was the name of Alfred wegeners idea?
Plate tectonics, which refers to the concept of continental drift.
