What is Alfred Wegener's hypothesis about the continents?
Alfred's hypothesis was that all the continents were a big land mass which he called Pangaea because if you see a world map it is like a jigsaw puzzle and other evidence is that some animal fossils were on other continents. Also the same rock range was found on different continents.

This hypothesis is known as 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.
Why was the wegeners hypothesis o the continental drift not widely accepted at the time it was proposed?
Wegener hypothesized that, on earth, there was only one continent called Pangea, but it split into the continents we have now. Improved Another Answer: Wegener's hypothesis was that long 225 million years ago, there was a supercontinent called Pangaea (All the continents were all together). Wegener saw that South America and Africa looked like they could fit together like puzzle pieces. He then found that there were fossils of animals in a warm climate and…
One of Wegeners theories was based off of evidence from fossils. These fossils were the Glossopteris plant fossil found in nearly every of the seven continents including Antarctica. And the other fossil was the Mesosaurus land reptile fossil found on Africa and South America which are continents now seperated by vast oceans proving Wegeners theory because these reptiles and plants couldnt have swam or drifted across these large oceans.
Wegener attempted to explain how continental drift took place. He suggested that the continents plowed across the ocean floors. Unfortunately, Wegener could not provide a satisfactory explanation for the force that pushes or pulls the continents. Because Wegener could not identify the cause of continental drift, most geologists rejected his idea.
Alfred Wegener was the scientist who championed the Continental Drift Theory through the first few decades of the twentieth century. Simply put, his hypothesis proposed that the continents had once been joined, and over time had drifted apart. The jigsaw fit that the continents make with each other can be seen by looking at any world map. For Example: Continents of Africa and South America joined together.
