I believe his first observation was the way the continents of South America and Africa "fit" together like a jigsaw puzzle (although he was not the first to realize this). He also made note of fossil discoveries in Africa which corresponded to those in South America. Finally, he began his own research which actually alligned rock formation/componants from one side of the Atlantic with the other.
No, Alfred Wegener did not use sea-floor spreading, ridge push, or slab pull to develop his hypothesis of continental drift. Wegener proposed his theory in 1912, long before these concepts were formulated in the mid-20th century as part of the theory of plate tectonics. Instead, Wegener based his hypothesis on evidence such as the fit of continental coastlines, fossil distribution, and geological similarities across continents. The mechanisms of sea-floor spreading and plate tectonics were developed later to explain the movement of continents.
One of His Theorys of continental drift was, that you could fit the continents back together if you had pictures. Also it would make up Pangea
No, the hypothesis that continents 'drift' was first put forward by Abraham Ortelius in 1596 and was fully developed by Alfred Wegener in 1912. Koppen is most widely known for his development of a climate classification system. More information follows on the Related Link listed below:
No, John Tuzo Wilson did not contribute to Alfred Wegener's continental drift theory. Williams was a geophysicist known for his research on plate tectonics, which built upon Wegener's ideas. He helped further develop the theory by proposing the concept of transform faults and the Wilson Cycle.
Yes, Wegener did use evidence of glacial striations to support his theory of continental drift. He observed that matching glacial striations on continents separated by oceans suggested they were once connected and had moved apart. This was one of the pieces of evidence Wegener used to develop his theory of plate tectonics.
The observation that led Alfred Wegener to develop the hypothesis of continental drift was that the continents looked like a puzzle that could fit together and then found out that fossils of similar kind and whats left of similar plants were found on opposite sides of the world.

hotspots on the ocean floor
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.
Alfred Wegener used fossil evidence, particularly the presence of identical plant and animal fossils on continents that are now separated by oceans, to develop the theory of continental drift. This suggested that those continents were once joined together.

Wegener first noticed that it looked like South America coastline could "fit" into Africa's. After that he analysed both their continental shelve's and this showed an even closer fit. The thrid observation that brought about his theory of continental drift was that he found fossils of the same animals (can't remember any names off the top of my head sorry) in both Argentina and east Somalia, Africa. The animal is the Mesosaurus, a fossil known to live 270 million years ago. This animal was very unlikely to swim across the ocean, so the continents had to conjoined one time in the past. Hope this helps :)
Alfred Wegener did not develop the theory of climatic regions. He is, however, known for proposing the theory of continental drift, suggesting that Earth's continents were once joined together as a single landmass called Pangaea. This idea laid the foundation for the modern theory of plate tectonics.
About a century ago, Alfred Wegener noticed that some of the world's continents actually looked like they could fit together like puzzle pieces, even though they were hundreds or even thousands of miles apart. Additionally, fossils found in these "matching" areas seemed to be very similar. This led Wegener to develop his theory of continental drift, which most scientists today accept.
