Alfred Wegener used four main lines of evidence to support his theory of continental drift: the geometric fit of the continents, matching geological formations across continents, matching fossil distributions across continents, and evidence of past climates from glacial deposits. These pieces of evidence suggested to Wegener that the continents were once joined together in a supercontinent called Pangaea and had since drifted apart.
What else can I help you with?
How did wegener deduce what pangaea looked like?
Wegener deduced what Pangaea looked like by identifying matching geological formations, fossils, and rock types across continents. He noticed that the coastlines of continents fit together like a jigsaw puzzle and suggested that they were once connected as a single supercontinent, which he named Pangaea. By analyzing these pieces of evidence, Wegener proposed that Pangaea existed around 300 million years ago.
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 did Alfred Wegener use for evidence?
Alfred Wegener used several pieces of evidence to support his theory of continental drift, including the fit of continents like South America and Africa, similar rock formations and mountain ranges across continents, and the distribution of plants and animals. He also looked at evidence from fossils and ancient climate data to support his hypothesis.
Explain Wegener's theory of continental drift?
Wegeners theory was that the tectonic plates in the earth were moving and colliding with each other due to temperature changes and convection currents at the core of the earth. Due to these plates moving, he thought that continents were drifting apart from each other, he then looked at a map of the earth and concluded that certain continents such as Africa and South America looked as if they had been joined previously as they seemed to fit together like peices of a jigsaw puzzle.
What is the hypothesis that states that the continents were once one large mass that broke apart?
Pangea. Alfred Wegener proposed the theory of continental drift, that the landmasses of the Earth were connected and slowly drifted apart, in 1912. His justifications for his theory included how the various continents looked like they could fit together and proposed that either centrifugal force of the Earth's rotation or astronomical precession were the forces behind the drift.
What did Wegener see?
Wegener looked at a piece of cork under a microscope and saw box like objects inside the cork.
What two continents did Alfred Wegener think looked like they fitted together like puzzle pieces?
Alfred Wegener proposed that Africa and South America looked like they could fit together like puzzle pieces, supporting his theory of continental drift.
How did wegener deduce what pangaea looked like?

Which two continents did Alfred Wegener think looked like they fitted together like puzzle pieces?
Alfred Wegener proposed that South America and Africa looked like they could fit together like puzzle pieces, supporting his theory of continental drift.
What observations led to Alfred wegener to develop the hypothesis of continental drift?
The observation that led Alfred Wegener to develop the hypothesis of continental drift was that the continents looked like a puzzle that could fit together and then found out that fossils of similar kind and whats left of similar plants were found on opposite sides of the world.
Why did wegener think the continents moved?
Wegener proposed the theory of continental drift because he noticed how coastlines of continents seemed to fit together like pieces of a puzzle. He also observed similarities in rock formations, fossils, and climate across continents that suggested they were once connected. These observations led him to suggest that the continents had moved over time.
Wegener first began to think about his continental drift hypothesis when he noticed a similarity in on different continents?
Alfred Wegener noticed that the continents looked like they could fit together like a puzzle, particularly along their coastlines. This observation led him to propose the theory of continental drift, suggesting that the continents were once joined together in a supercontinent called Pangaea.

What evidence provides for continental drift?
About a century ago, Alfred Wegener noticed that some of the world's continents actually looked like they could fit together like puzzle pieces, even though they were hundreds or even thousands of miles apart. Additionally, fossils found in these "matching" areas seemed to be very similar. This led Wegener to develop his theory of continental drift, which most scientists today accept.
What evidence did Alfred Wegener use to support his theory of continental drift?
Deep-sea mountain ranges had caught his attention. Alfred Wegener's fully developed theory of continental drift attempted to point out evidences that the continents were once joined into a single continent he called Pangaea. Wegener's theory hypothesized that the continents were able to push through the rock of the seafloor to their present positions. As evidence, he noted (as had others before him), of the geographic correlation in coastline perimeters of South America and Africa. This was the feature that led Wegener to investigate other clues. His investigations revealed that mountain ranges in South America and Africa, and strata and composition of coal fields in Europe and North America matched or lined up. Additionally, matching reptilian fossils were found on either side of the ocean, indicating that the continents were once joined together. Although he was unable to find a mechanism for his proposed continental drift theory, he also observed that the more shallow an ocean, the younger its geologic age. It wasn't until the 1950's and 1960's, with the discovery of the Mid-Atlantic Ridge (and other sea floor mapping discoveries) that Wegener's hypothesis started to become more accepted. The newer science of plate tectonics owes much to Wegener's scientific groundwork. sdhtshehdtubt6yhsx ryjut7iyldrtysvefgb 6u fyu6uerjthe5tjkj jgyuftyk
Albert wegener theory is true?
yes because i looked at a map and tried to put the continents back together with my brain and they fit perfect and Albert Wagner had clues there was the same climates the same land formations and the same fossils that is why i think his theory is correct
