How did Wigner use the island of Spitsbergen to support the theory of continental drift?
First of all it is Wegener, Alfred Lothar Wegener to be percised. He was a german scientist who had the hypothesis for continental drift. His hypothesis got rejected by other scientist because it interferred with their ideas on how mountains form.Wegener used Spitsbergen to support his evidence for continental drift because Spitsbergen is now a snowy reigon and geoigists had found fossils of tropical plants.Tropical plants cannot grow in a snowy reigon.
How do fossils support the evidence of pangaea?
Pangaea implies at some part in the Earth's evolution, probably before the rise of mammals and intelligent life ( Man) there was one major world continent that since has split up into the present seven. As life of intelligent type did not exist at the time, there is no way fossils can be dragged in to prove things one way or the other, though it does have a relative bearing on Atlantis and Atlantean studies.
Why wasn't Wegener's theory of Pangaea accepted at first?
His idea was not accepted because people back then did not believe that the plates could move. They also thought you could fall off the Earth but that is a different question. The theory was put forward first by Abraham Orthelius but was fully developed by Alfred Wegner. His theory was not thought of because people thought it was not possible for the tectonic plates of the earth to move.
Why was Wegeners hypothesis rejected by most scientists of his day?
Wegener made a strong case for continental drift as you may know. E.g. similar rock strata on opposing continents, similar fossil types located in geographically distant regions, evidence of glaciation and the general jig-saw fit of the continents. He could not explain however how the continents moved, that is, what force was acting on them and causing them to drift. He suggested that a combination of centrifugal force from the Earth's rotation and gravitational forces from objects in space (similar to what causes tides) moved the continents. Calculations proved this to be impossible. Since he could not explain the mechanism because little about plate tectonics was known at the time, his ideas were not widely accepted in the scientific community.
How did climate support wegener's theory?
Tectonic plates
How long was it before new evidence emerged to support wegener's original theory?
In the 1960's scientists uncovered new evidence that seemed to support Wegener's theory.
Which type of evidence was not used by Alfred wegener to support his continental hypothesis?
Which type of evidence was NOT used by Alfred Wegener to support his continental drift hypothesis human remains

Why scientists rejected wegener's hypothesis of 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.
What types of evidence was used by Alfred Wegener to support his continental drift hypothesis?
human remains
Did Alfred wegener believe that continental drift explained fossils of tropical plants found in places that today have a polar climate?
Yes he did. When Wegener was trying to convince people that millions of years ago there was only one super continent (Pangaea) he used facts like glossopteris fossils being spread across different continents to support his evidence.
What are pieces of evidence that support the idea of Pangaea?
Continental Fit, Fossil Evidence and Sea floor Spreading. I just did this in science a month ago. :)
How did Alfred Wegener use rock and fossil evidence to support his hypothesis-?
Wegener used the fit of the continents, the distribution of fossils, a similar sequence of rocks at numerous locations, ancient climates, and the apparent wandering of the Earth's polar regions to support his idea.http://kids.earth.nasa.gov/archive/pangaea/evidence.htmlin other words rock types and agesRock types and ages.
What pieces of evidence Alfred wegener used to support his theory?
The pieces of evidence Alfred Wegener used to support his theory about continental drift were; Puzzle Fit, Fossil evidence from animals that were once on the same continent, geologic evidence like mountain chains that were connected and now split apart, and ice sheets. Thank you for reading this article and I hoped it answered your question!
Is it true that Alfred wegener provided evidence from landforms fossils and climate to support his theory of the shrinking earth?
true
What evidence of land feautures did Alfred wegener use?
Alfred Wegener used various pieces of evidence to support his theory of continental drift, including the fit of the continents, rock and fossil similarities across continents, glacial evidence, and similar geological features on different continents.
Why is a hypothesis that is unsupported by observation rejected by scientists?
Simply put, because there is not enough evidence to support it. "Rejected by scientists" should not be taken to always mean "scientist believe it is impossible" - rather, consistent evidence that support the hypothesis has not been produced.
