What is the theory called for the continents joined together?
The theory is called plate tectonics, which explains how the Earth's lithosphere is divided into large plates that move and interact with each other, leading to phenomena such as continental drift and the formation of mountains and ocean basins.
Where did wegener look for proof that would support his theory of continental drift?
Alfred Wegener looked for several lines of evidence to support his theory of continental drift, including the fit of the continents like puzzle pieces, matching geological formations across continents, similarities in fossils and plants, and evidence from paleoclimate data such as glacial deposits.
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 would wegener have considered the presence of coal in Pennsylvania evidence of continental drift?
Wegener would have considered the presence of coal in Pennsylvania as evidence of continental drift because coal forms from the remains of ancient plants, which typically grow in swampy environments. The presence of coal in Pennsylvania suggests that the region was once located in a different climate zone, which aligns with the idea of continents moving over time. This supports Wegener's theory of continental drift, which proposed that the continents were once connected and have since moved apart.
How was the theory of continental drift strengthened by discoveries of closely related earthworms on widely separated continents?
The continental drift theory was strengthened by several discoveries of similar species on widely separated continents. The basic idea was that if Continent A, say, Africa, had a fossil of a certain worm on its west coast, while Continent B, South America, had a fossil of the same worm on its eastern coast, it would only make sense that at one time these continents had to be joined to allow for this species to flourish in both areas at once. The only other possible explanation would be that the worms swam across the ocean...which isn't exactly feasible considering that they are, in fact, worms.
Idea that contineents have moved horizontally through the seafloor to their current locations?
the theory would be called Continental drift.
Who first stated the theory of continental drift?
That would be Alfred Wegener.yah! it's true ALFRED L. WEGENER [1880-1930] who first proposed the CONTINENTAL DRIFT IN 1912. obejerojamjam@yahoo.com :))

Why did most scientists originally reject the theory of continental drift?
Most scientists originally reject the theory of continental drift since it did clearly explain continents would move. This is a theory that has been established by Wegener and did not get good support initially.
Is there any other theory that would disprove bohr's atomic theory?
yes

What is the weakness in Wegener's continental drift hypothesis?
A weakness in Wegener's continental drift hypothesis was the lack of a mechanism explaining how the continents moved. Additionally, he was unable to provide evidence supporting the force that would be strong enough to move continents across the Earth's surface. Lastly, Wegener's theory faced skepticism from the scientific community at the time due to a lack of detailed data and observations supporting his idea of continental drift.
What is Archie Carr's contribution to continental drift?
Archie Carr's proposing theory that as Brazil spread away from the Mid-Atlantic ridge and Ascension Island, the green turtle returned to the island year after year to lay eggs. The hatchlings would have to swim back further each time 2cm/yr until today when they swim back 1200 miles. I believe this to support Wegener's theory.

What is the evidence missing from Alfred Wegener's continental drift theory?
The only evidence that Alfred Wegener did not have was the mechanism that drove the Continental Drift, he had evidence to support that the continents were once joined together, but did not have the means to postulate how the continents had actually moved to their present positions. He did however postulate the theory of a "layered Earth" consisting of a rigid surface (continents) upon a liquid/plastic like substance (mantle) and that if pressure was exerted on the surface layer, it would move thus, and if the pressure was removed the surface would return to its original state. It was only until c. 1890, when the Geophysicist Arthur Holmes came up with the theory of convection currents in the mantle being responsible for Continental Drift.
How fossils support the theory of continental drift?
We find matching types of ancient fossils separated on coinciding land masses across the Atlantic Ocean, where Brazil would abut Africa.
Why is the theory of the continental drift important?
The theory of continental drift is important because it revolutionized our understanding of Earth's geological processes and how continents have shifted over time. It provided a framework for explaining the distribution of fossils and rock formations across continents and led to the development of plate tectonics theory, which has further advanced our understanding of earthquakes, volcanoes, and mountain formation. This theory also helps us understand past climates, ocean currents, and the evolution of life on Earth.
