Alfred Wegener, a German meteorologist and geophysicist, first proposed the theory of continental drift in the early 20th century. He noticed the puzzle-like fit of the continents, suggesting that they were once joined together in a single landmass he called "Pangaea."

What were the three things that Alfred wegener used to prove the theory of continental drift?
Alfred Wegener used the fit of the continents, fossil evidence, and rock formations to support his theory of continental drift. He noticed how the continents seemed to fit together like a jigsaw puzzle, found similar fossils on different continents, and discovered matching rock layers across continents. These pieces of evidence led him to propose the idea of Pangaea and the movement of continents over time.
How did fossils provide evidence for continents drifts?
because if the same fossils were found in the same spot but on two different continents and if you put the continents together like a puzzle and the fossils were in the same spot, it would mean the continents drifted apart.
Alfred wegener noticed that the cost of south America fit like a jigsaw puzzle?
Alfred Wegener observed the apparent fit of the coastlines of South America and Africa, suggesting they were once joined. This observation helped support his theory of continental drift, which proposed that continents were once connected in a single landmass called Pangaea and drifted apart over time. This theory laid the foundation for the modern theory of plate tectonics.
Alfred wegener noticed that the coast of south America seemed to fit into the coast of the continent just like a jigsaw puzzle?
Yes, Alfred Wegener observed that the coastlines of South America and Africa appeared to fit together like puzzle pieces. This observation was a key piece of evidence in support of his theory of continental drift, which proposed that the continents were once connected as a single landmass before drifting apart over time.
When was it noticed that continents fit together?
The first observation that continents seemed to fit together like puzzle pieces was made in the late 16th century by Abraham Ortelius, a Flemish cartographer. However, the theory of continental drift, proposing that continents were once part of a single supercontinent, was popularized by Alfred Wegener in the early 20th century.
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.
Why did Wegener think that the continents might once have been joined?
Wegener noticed that the coastlines of continents seemed to fit together like puzzle pieces, and that similar fossils and rock formations were found on opposite sides of the Atlantic Ocean. He proposed the theory of continental drift, suggesting that the continents were once connected in a supercontinent called Pangaea and had since drifted apart.
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.
What did Alfred wegner notice about the outlines of the continents?
Alfred Wegener noticed that the outlines of the continents seemed to fit together like pieces of a jigsaw puzzle, particularly the coastlines of South America and Africa. This observation led him to develop the theory of continental drift.
How are the continents like a jigsaw puzzle?
they are like jigsaw puzzle because scientist don't know where places fit
What did mapmakers notice about the shape of the continents?
Mapmakers noticed that the shapes of continents appeared to fit together like pieces of a jigsaw puzzle, suggesting they were once joined together. This observation contributed to the development of the theory of continental drift and later the theory of plate tectonics.

Edges of some continents look as if they would?
The edges of some continents look as if they would fit together like pieces of a puzzle.
What did wegener notice about the continents?
Wegener noticed that the continents appeared to fit together like a jigsaw puzzle, especially when looking at the coastlines of South America and Africa. He also observed similarities in rock formations, fossils, and mountain ranges across continents that suggested they were once connected. This led Wegener to propose the theory of continental drift.
What evidence supports wegener's hypothesis?
All of the continents fit together like a puzzle.
How did Alfred Wegener knew that the 7 continents were once a supercontinent and how did he develop the Continental Drift Theory?
Alfred Wegener noticed that the coastlines of continents appeared to fit together like a jigsaw puzzle and found similar rock formations and fossils on different continents. He proposed the Continental Drift Theory by suggesting that all continents were once part of a single supercontinent called Pangaea, which later broke apart and drifted to their current positions over millions of years.
What do you see that could have lead observers such as Alfred Wegener to hypothesize that the continents have moved?
Alfred Wegener and others noticed that the shapes of continents seemed to fit together like pieces of a jigsaw puzzle, similar fossils and rock formations appeared on different continents, and evidence of past climates that were not possible in current locations. These observations led them to hypothesize that the continents had moved over time, which eventually became the theory of plate tectonics.
