When did alfred wegener discover pangaea?
Alfred Wegener proposed the theory of Pangaea, the supercontinent, in 1912 based on his ideas of continental drift. However, his theory was not widely accepted until after his death in 1930 when further evidence supported the idea of plate tectonics.
What theory did Alfred wegener proposed first?
Alfred wegeners theory of continental driftIs that once all the continents were all join as one massive land mass. (and split apart.)
What are three things that wegener used to develop his theory of continental drift?
Wegener used evidence from fossils, rock formations, and the fit of the continents as key components to develop his theory of continental drift. By studying these factors, he proposed the idea that all continents were once part of a single supercontinent called Pangaea.
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.
If you were able to travel back through time and meet with Alfred wegener hou could you explain to his detractors that the theory of continental drift was correct?
If I was able to travel back in time, I wouldn't be talking to Wegener's detractors, but if I did, I would say something like this: "I'm from the future. I know this sounds silly, but we've mapped the bottom of the ocean and discovered these things called mid-ocean ridges which are present in every major ocean. The rocks on either side of the ridge get older the further away from the ridge you go. Scientific instruments actually can measure this movement of the plates, and it's somewhere in the neighborhood of the rate of fingernail growth. We've also been to the moon and back and sent robots to Mars. Furthermore we've....HEY, LEAVE ME ALONE. PUT ME DOWN!...."

What were the three things that Alfred wegener used to prove the theory of continental drift?
Alfred Wegner had 4 theory`s,Climate evidence,Fossil evidence,the continents fitting together like a puzzle,and horizontal movement. The fossils were different types of ancient ferns and Dinosaurs.
What showed proof for Alfred Wegener on Pangaea?
We know Pangaea existed because of fossil evidence. There were fossils of the same animal found on Africa and South America. This animal couldn't have possibly swam across the ocean. Therefore, making the idea of Pangaea plausible.
What is theory for fossils of tropical plants found on an island in the arctic ocean?
The theory for fossils of tropical plants found on an island in the Arctic Ocean is that the island was once situated in a tropical or subtropical region, and through the movement of tectonic plates, it shifted to its current location in the Arctic. This suggests that the climate of the island has significantly changed over time due to the shifting of the Earth's landmasses.

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.
What does computer modeling show about the breakup of Pangaea?
It shows that Pangaea was a long continent that crossed the equator. Asia & North America then split from the other continent. Antarctica split off the rest.
How did hilde the child of Alfred wegener die?
Hilde, the child of Alfred Wegener, died tragically in a sledging accident during an expedition in Greenland. She fell through the ice and drowned, leaving her family devastated. It was a heartbreaking loss for the Wegener family, and a reminder of the dangers of exploring the harsh Arctic environment.
'what is the assumptions of economics by Alfred marshall'?
Alfred marshall made a heroic assumption of 'cetris paribus' which means other things being equal/constant in economics. This assumption he used for the theories he put forth viz. theory of demand,theory of supply,theory of diminishing marginal utility,etc. Most of his theories come under the sub field- micro economics. The assumption of cetris paribus is the main, there are many others for each law besides cetris paribus.
What was his theory of evolution?
The theory of evolution is that all living things come from other living things.
