Alfred Wegener proposed the theory of continental drift, suggesting that the continents were once joined together in a single landmass called Pangea and have since drifted apart to their current positions on Earth's surface. He believed that the continents moved slowly over time due to the process of plate tectonics.

How did Wegener explain the way the continents moved?
Wegener proposed the theory of continental drift, suggesting that the continents were once connected in a single landmass called Pangaea. He proposed that the continents drifted apart over time due to the movement of the Earth's crustal plates.
What did Alfred Wegener study about Pangaea?
Alfred Wegener was the first to propose the concept of Pangaea, that all the continents were once one super continent. He noticed mountain ranges that seemed to continue past the ocean. He noticed that there were the same species of fossils on two different continents, of animals that would have had no way to travel over oceans. With these and other facts, he concluded that the continents must have at one time been connected to each other, and had moved away from each other, by a process he called Plate Tectonics.
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 two continents?
The contry that has two continents is Russia. The two continents in Russia are Europe and Asia. By the way you could have googled "The seven continents of the world" in images it would have been much quicker.
What two continents coastlines led to early suggestion that they were joined at one time?
The coastlines of South America and Africa led to the early suggestion that they were joined at one time due to their similar shape, geological features, and the way certain plant and animal species were distributed across both continents. This idea eventually became known as the theory of continental drift, proposed by Alfred Wegener in the early 20th century.

Why didn't people believe Alfred wegener theory?
because they had no way of explaing how the continents could move

What are the four forms of evidence Alfred wegener used to support his hypothesis he called continental drift?
Alfred Wegener used fossil evidence (matching plant and animal species across continents), geological evidence (similar rock formations and mountain ranges on different continents), climate evidence (glacial deposits and ancient climate patterns that suggested continents were once connected), and fit of continents (the way the continents seem to fit together like a puzzle) to support his hypothesis of continental drift.
What evidence did wegener have to prove his hypothesis?
Alfred Wegener used several pieces of evidence to support his theory of continental drift, including the fit of continents like South America and Africa, similarities in rock formations and fossils across continents, and the matching of ancient climate indicators like glaciation patterns. Despite facing initial skepticism, Wegener's evidence paved the way for the development of the theory of plate tectonics.
What time does ice ages continental drift starts?
The theory of continental drift, which later led to the development of the theory of plate tectonics, was first proposed by Alfred Wegener in 1912. Wegener's ideas about the movement of continents and the concept of Pangea eventually paved the way for understanding how Earth's continents have shifted over time.
Why do you think our plants continents look the way they do today?
The shape of the continents is mainly due to water erosion.
Whose ideas later assisted in the recognition if Wegener's theory?
Arthur Holmes's ideas in the 1920s about mantle convection and radioactive heating helped support Alfred Wegener's theory of continental drift by providing a mechanism for how the continents could move. This helped pave the way for the eventual acceptance of Wegener's ideas as the theory of plate tectonics.
Give an example of evidence from land features that supported wegeners idea of continental drift?
An example of evidence from land features that supported Wegener's idea of continental drift might include the piecing together of map layouts which show the way that the continents fit together. Wegener is famous for sharing this example.
What do all continents have in common that paleontologists notice?
All paleontologists,(and other people), notice that on every continent, there were similar fossils. Obviously, not all prehistoric/Precambrian organisms could swim all the way across oceans, so the continents had to have moved. This proved Wegener's hypothesis(some really old scientist i learned about in science class)which was continental drift.
What did people think about Alfred wegener's theory?
Wegener's theory of continental drift was met with skepticism when first proposed in the early 20th century. Many scientists rejected it because he lacked a plausible mechanism for how continents could move. It wasn't until the discovery of plate tectonics in the 1960s that Wegener's ideas gained widespread acceptance.
