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 is theory for fossils of tropical plants found on an island in the arctic ocean?
the theory called the "continental drift" hypothesized that all the continents were once a huge supercontinent but then eventually over time spread apart. this is ALFRED WEGENER (veh-gen-er) HYPOTHESIS IN 1910.
What are two things that support the continental drift theory?
Two things that supports the continental drift theory are; 1. Fossil. 2. Continent Shapes.
What theory supports the continental drift theory?
The idea that the continents were once one super-continent and subsequently moved apart is the basis of the theory of continental drift. Continental drift was first proposed as a scientific hypothesis with evidences by Alfred Wegener early in the twentieth century. Unfortunately, the evidence he was able to cite, such as similarities in coastline geographies and fossils on either side of the Atlantic, did not provide an explanation for the mechanism which caused it to happen. In Wegener's theory, the continents were somehow able to plow through the oceans. It wasn't until the mid-twentieth century that the Atlantic Ridge system was discovered. Further investigation revealed that the magnetic orientation of rock on either side of the ridge matched the orientation on the other side of the ridge, providing the proof for the mechanism that caused the continents to move apart. Basaltic magma was infilling the area on either side of the ridge to create new continental crust. Subduction of older, denser oceanic crust takes place at collision zones where it meets less dense oceanic and continental crust. The whole process is driven by gravity and heat from the Earth's interior via convection currents in the mantle. The process is no longer called continental drift, but is referred to as plate tectonics.Alfred Wagner's theory was that the sea floor was spreading, causing the continents to 'drift'. The theory was originally tossed aside because the fact that the continents fitted together was not sufficient.
What was his theory of evolution?
The theory of evolution is that all living things come from other living things.
What is the name of the theory that all living things are made of cells?
the cell theory

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 the three things Alfred Wegener used to prove his theory about pangaea?
Fossils, Climate, and Sea-Floor Spreading
When did alfred wegener discover pangaea?
in 1915 wegener figuered out about Pangaea because of three things climate change fossils and land features

What was NOT used by Wegener to support his hypothesis of continental drift?
The ratio of the price of tea in China to the average density of the Moon. Among other things. You might want to be more specific in questions like this.
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 were the three things called that Alfred Wagner used to prove continental drift?
1. Continents fit like puzzles 2. Fossil evidence 3. Past climate changes
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!...."
Is there such things as continental drift?
Yes
'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.
