What is wegeners phypothesis about earths continents have moved?
Alfred Wegener's hypothesis of continental drift proposed that all continents were once connected in a single supercontinent called Pangaea. Over time, Pangaea broke apart and the fragments drifted to their current positions. Wegener's idea eventually led to the development of the theory of plate tectonics.
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.
What were Alfred wegeners accomplishments?
he theorized about the continental drift and he also said that a pangaea formed 200 million years ago
What was alfred wegeners hypothesis about continental drift?
States that the continents were once a single huge landmass. This landmass broke up million years ago and the pieces drifted apart. facing edges of many continents have similar rock formations. If the continents brought togehter, the formations would match exactly (like combining South America and Africa). Fossils of the same kinds of living things have been found on different continents. Perhaps these living things were together on one landmass before it split.
What do scientists now know about earth that would have answered the scientists who rejected wegeners theory?
Scientists now know about plate tectonics, which explains how Earth's outer shell is divided into large plates that move and interact with each other. This understanding supports Wegener's theory of continental drift, as it provides a mechanism for the movement of continents over time. Additionally, evidence from ocean floor mapping, seafloor spreading, and magnetic striping further supports the concept of plate tectonics.
Wegeners hypothesis of continental drift was replaced in 1967 by which theory that supported his idea continents move?
plate tectonics
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.
Wegeners hypothesis of continental drift was finally confirmed by?
evidence supporting the idea of sea-floor spreading.
What is the theory that plates have moved apart over tmie?
Alfred Wegeners 1912 theory of Plate tectonics and continental drift.
What were Alfred wegeners beliefs about the Plate tectonics?
@ his time plate tectonics was not theorized. they didnt know yet that continental and oceanic crust are seperate. it was thought that continents were drifting on water and moved some million years ago due to erosion,etc! hence the "continental drift theory"
What evidence did Wegeners have to support his theory?
Fossils support his hypothesis.
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.
Why was the wegeners hypothesis o the continental drift not widely accepted at the time it was proposed?
Although it seemed to make a lot of sense, there was no known proof of HOW the continents would drift. It wasn't until years later that we gained knowledge of plate tectonics, which bolstered Wegener's hypothesis.
What is wegeners phypothesis about earths continents have moved?
Alfred Wegener's hypothesis of continental drift proposed that all continents were once connected in a single supercontinent called Pangaea. Over time, Pangaea broke apart and the fragments drifted to their current positions. Wegener's idea eventually led to the development of the theory of plate tectonics.
Does the case of mesosaurus support wegeners theory of continental drift?
yes it does.
Why was wegeners idea denied?
The scientific means for proving his hypothesis had not yet been developed.
