What was alfred wegeners evidence for continental drift?
i.e. continental fit across the Atlantic Multiple species matches (best of which where shallow water or terrestrial where it was infeasible for them to cross such a large water mass) Mountain ranges fitted together both sides of the Atlantic
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.
What was the weakness of wegeners proposal of continental drift?
One weakness of Wegener's proposal of continental drift was the lack of a mechanism to explain how continents could move. Additionally, Wegener's theory was not widely accepted at the time due to insufficient supporting evidence and the reluctance of the scientific community to accept such a radical idea.
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.
Does the case of mesosaurus support wegeners theory of continental drift?
yes it does.
What was the reason wegeners continental drift hypothesis was rejected?
His evidence was incorrect.
What was the name of Alfred wegeners idea?
Plate tectonics, which refers to the concept of continental drift.
Why were most scientists disagreeing with Alfred Wegeners continental drift theory?
There was no evidence to prove it
What was Alfred wegeners accomplishments?
He proposed the idea of continental dift, which is very cool!
Why most geologists rejected Alfred wegeners idea of continental drift?
dont ask me freak
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 was the main reason wegeners continental drift was rejected?
He could not provide a wholly acceptable explanation for the movement of the continents.
Why was wegeners theory of continental drift not accepted at first?
It was not excepted because they didn't believe him at all until it was proven!
What is the theory that plates have moved apart over tmie?
Alfred Wegeners 1912 theory of Plate tectonics and continental drift.
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.
