In what two ways is the plate tectonics theory different from the ideas of continental drift?
k
What is the plate tectonics theory?
The theory of plate tectonics says that the Earth's lithosphere is divided into "plates" that are determined by overall movement.The theory combines ideas on seafloor spreading and continental drift
Which was an idea used to dispute the theory of plate technonics?
One of the ideas that was used to dispute the theory of plate tectonics was the concept of "fixism" or "fixist theory." Fixism proposed that the positions of continents and landforms on Earth were permanent and unchanging. According to fixism, the continents were believed to be stationary, and there was no mechanism for their movement or shifting. Fixism was prevalent in the early 20th century and before, with many geologists and scientists rejecting the idea of continental drift, which eventually led to the development of plate tectonics theory. However, as more evidence accumulated, particularly in the mid-20th century, supporting the movement of continents and the presence of large-scale tectonic plates, the theory of fixism was gradually abandoned in favor of the more widely accepted theory of plate tectonics.
What convinced scientists that Wegener's theory of continental drift was true?
While Wegner's theory of continental drift assumed that continents plowed through and over oceanic crust, his basic ideas are still upheld today. As a result of submarines and radar technology used in WWII, scientists were better able to map the seafloor. In doing so they discovered the seafloor's topography, age, magnetism, and the Mid-Atlantic Ridge. After discovering that the seafloor did spread apart and that continents moved, Wegner's theory gradually became accepted.
Was the theory of a 'super continent' originally accepted by scientists?
When German meteorologist Alfred Wegener first published his theory on Pangea (super continent) he was widely ridiculed for it. Some of the reaction to his theory on continental shift and a super continent was actually quite hostile. The idea was first put forward in 1912 but it wasn't until the 1950's that his idea was really rethought. By then evidence of continental drift was starting to support his ideas.

It isnt its the same thing-plate tectonics create the idea of continental drift.

What two ideas did plate tectonics combine?
Plate tectonics combines continental drift and seafloor spreading theories, presenting the latter as a reason for the former.
Key ideas of the Theory of Continental Drift?
The continental drift theory is the theory that once all of the continents were joined in a super-continent, which scientists call Pangaea. Over a vast period of time, the continents drifted apart to their current locations.
Who is Alfred wegler?
Alfred Wegener was a German meteorologist and geophysicist who proposed the theory of continental drift in the early 20th century. He suggested that the continents were once joined together in a single landmass called Pangaea and have since drifted apart. Wegener's ideas laid the foundation for the modern theory of plate tectonics.
Who is considered the father of plate tectonic theory?
Alfred Wegener is considered the father of plate tectonic theory. He proposed the theory of continental drift in the early 20th century, suggesting that continents were once connected in a supercontinent called Pangaea and have since moved apart. While his ideas were initially met with skepticism, his work paved the way for the development of the modern theory of plate tectonics.
Hypothesis that the continents have moved slowly to their current locations?
The theories of continental drift and plate tectonics. These are relatively new ideas; when I was young, they were still fairly controversial. But as the evidence has accumulated, most people have become convinced that these are valid explanations of how things came to be as they are. Just remember that the next time somebody says that something is "settled science"; the science of any discipline is NEVER settled.
What scientist proposed the first formal theory of continental drift?
Continental Drift was put forward by Alfred Wegener.(1880-1930). One piece of evidence on which he based his ideas was the similarity of shapes of the South American and African coastlines. Another was the fact that the same types of fossil are found in both places.
What difficulties do scientists experience as they attempt to introduce breakthrough ideas?
Having their ideas accepted by other scientists, their sponsors, and the public. Louis Pasteur was vilified for his ideas on germs and germ theory; it took a generation for his ideas to catch on. Simillarly, the idea of continental drift was long rejected, but eventually caught on.
