No mechanism for his theory
Many geologist did not accept Wegener's theory because there was no mechanism to explain his observations.
Alfred Wegener proposed the theory of continental drift from which he explained the land masses on earth were once joined together.
He used evidences of;Similar fossils found in different places today. Tropical plant fossils found in polar regions. Similar mountains found on different continents today.
His theory was rebuffed because there was no sound mechanism to explain for why the continents drifted.
The theory of seafloor spreading and plate tectonics later explained Wegener's claims.
the answer is:
a. Wegener could not explain how similar fossils could be found on different continents.
The correct answer is C. No one coud provide a good explanation for how huge continents could have moved across the earth's surface.
The continental drift theory is a geological theory developed by Alfred Wegener in the early twentieth century. In it, this German geologist proposed that the shape of the continents could fit together like pieces of a puzzle and formed a single continent, indicating that over time they moved to form the continents as we know. Additionally, he found that some fossils from the northern continents were equal and came from the same geological ages. However, many geologists of the time rejected this theory because Wegener did not propose a mechanism to explain this movement of the continents, and therefore it was difficult to believe these huge masses could move. So, the correct answer is C. No one coud provide a good explanation for how huge continents could have moved across the earth's surface.
Wegener could not explain how similar fossils could be found on different continents.
