Alfred Wegener proposed the theory of continental drift in 1912, suggesting that continents were once joined together in a single landmass called Pangaea. He suggested that the continents moved horizontally over time due to the process of continental drift, driven by forces such as seafloor spreading and mantle convection.
What else can I help you with?
Why did wegener believe that the continents were just one big landmass before?
Wegener believed in the theory of continental drift because he noticed that the coastlines of continents seemed to fit together like pieces of a puzzle. He also found similarities in rock formations and fossils across different continents, suggesting they were once connected. These observations led him to propose that the continents were once part of a single supercontinent called Pangaea.
What did Alfren Wegener present as evidence that the continents move?
Alfred Wegener presented several lines of evidence to support his theory of continental drift, including the fit of the continents like a jigsaw puzzle, similarities in rock formations and mountain ranges across continents, and the distribution of fossils of the same species on different continents separated by oceans.
Why the continents could not possibly move the way wegnener is describing?
During Wegener's time, the mechanism for how continents could move was not understood. Without knowing about plate tectonics, scientists found it hard to believe that continents could plow through the dense oceanic crust. Additionally, Wegener lacked concrete evidence to support his theory, making it challenging for others to accept his ideas.
What are the arguments against the wegener continents theory?
Some arguments against Alfred Wegener's theory of continental drift include lack of a plausible mechanism to explain how continents could move, insufficient evidence to support the idea of continents drifting over time, and skepticism from the scientific community at the time due to the lack of detailed data and research. Additionally, Wegener's theory faced opposition because it challenged the widely accepted theory of fixed continents.
What made Alfred wegener think the continents move?
Alfred Wegener proposed the theory of continental drift in the early 20th century because he observed similar plant and animal fossils on continents that are now far apart, as well as matching geological formations and evidence of ancient climates that suggest the continents were once joined together and have since drifted apart.
What did Alfred Wegener propose in 1912?
Alfred Wegener proposed the theory of continental drift in 1912, suggesting that the Earth's continents were once joined together in a single supercontinent called Pangaea and have since drifted apart to their current positions. He argued that the continents move slowly over time due to tectonic plate movement.
Who is Albert wegener?
Albert Wegener is a scientist who discovered that the continents move, to form a super continent pangea. His findings weren't proven until after his death.
Why did wegener believe that the continents were just one big landmass before?
Wegener believed in the theory of continental drift because he noticed that the coastlines of continents seemed to fit together like pieces of a puzzle. He also found similarities in rock formations and fossils across different continents, suggesting they were once connected. These observations led him to propose that the continents were once part of a single supercontinent called Pangaea.
What was one question that Alfred wegener could not answer?
One question Alfred Wegener could not answer was the mechanism that caused the movement of continents, as he proposed the theory of continental drift before the discovery of plate tectonics. He could not explain how or why continents would be able to move through solid oceanic crust.
Why didn't people believe Alfred wegener theory?
because they had no way of explaing how the continents could move
Why did Wegener's idea get rejected by scientists?
Scientist rejected Wegners hypothesis of continental drift at first because he did not have enogh evidence to support his theory. He failed to provide a suitable mechanism that could cause the continents to move.

What information did Wegener not have?
Alfred Wegener did not have a mechanism to explain how continents could move across the Earth's surface. He proposed the theory of continental drift in the early 20th century, but it wasn't until the development of plate tectonics in the 1960s that a satisfactory explanation for the movement of continents was provided.
What are the arguments against the wegener continents theory?
Some arguments against Alfred Wegener's theory of continental drift include lack of a plausible mechanism to explain how continents could move, insufficient evidence to support the idea of continents drifting over time, and skepticism from the scientific community at the time due to the lack of detailed data and research. Additionally, Wegener's theory faced opposition because it challenged the widely accepted theory of fixed continents.
What did Alfred Wegener fail to do?
Alfred Wegener's theory of continental drift was initially met with skepticism because he was unable to provide a mechanism for how continents could move. Additionally, his hypothesis lacked strong geological evidence to support the movement of continents being driven by tectonic forces. Ultimately, Wegener's failure to address these concerns resulted in his theory being widely rejected during his lifetime.
What was the weakness in Alfred Wegener's theory of continental drift?
The theory was dismissed by the scientific community because there was no mechanism to move continents through what was believed to be solid rock.Here is one of the reasons that the theory was hotly debated when it came out in 1912: Link:http://www.youtube.com/watch?v=94AiYYgtIEw
