Wegener believed all continents had once been joined because of the similar shapes of Coastlines, matching geological formations across continents, and evidence of past glaciation extending from multiple continents, suggesting they were once connected.
What else can I help you with?
Who first noticed how the continents fit together in 1911?
Alfred Wegener first proposed the theory of continental drift in 1912, in which he suggested that the continents had once been joined together in a supercontinent called Pangaea. While his ideas were not widely accepted during his lifetime, they later formed the basis for the theory of plate tectonics.
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.
If you were Wegener what other evidence would you look for to show that the continents had once been joined?
If I were Wegener, I would look for matching geological features on different continents, such as similar rock types, mountain ranges, and fossils. I would also investigate any evidence of past climate change that could support the idea of continents moving. Additionally, I would search for remnants of ancient land bridges or plate boundaries to further support my hypothesis of continental drift.
How did Wegener propose that the continents drifted?
Alfred Wegener proposed the theory of continental drift in 1912, suggesting that the continents had once been part of a single supercontinent called Pangaea. He suggested that the continents slowly drifted apart over millions of years due to the movement of the Earth's tectonic 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.
What did Wegener and hypothesis of continental drift propose?
Alfred Wegener's theory was that once the continents had been joined together, and that somehow, the continents had drifted apart. His theory turned out to be right, and his theory's name was, of course, "Continental Drift."
What did Alfred Wegener propose after looking at the rock sequences on different continents?
Alfred Wegener proposed the theory of continental drift after observing that the rock sequences and fossil assemblages on different continents matched up when they were thought to have been part of a single supercontinent. He suggested that the continents were once connected and had drifted apart over time.
List three puzzling occurrences that wegener's theory helped explain and describe how if explained them?
The distribution of fossils of the same species across continents provided evidence of past connections between continents, supporting Wegener's theory of continental drift. The matching geological features on opposite coastlines of continents suggested they were once connected and later drifted apart, which aligns with Wegener's theory. The jigsaw-like fit of the continents' coastlines, particularly on the Atlantic Ocean, offered a strong visual representation of how continents could have been joined and later separated, supporting Wegener's theory of continental drift.

Did Alfred Wegener believe that Earth's climate had changed?
Yes, Alfred Wegener proposed the theory of continental drift in the early 20th century, which suggested that Earth's continents had once been connected in a single landmass called Pangea. He used evidence from fossils and geological formations to support his theory, indicating that Earth's climate had changed over time as the continents drifted apart.

What information or items did Alfred wegener support his theory?
Alfred Wegener supported his theory of continental drift by comparing the shapes of continents, similarities in rock formations, fossil evidence, and paleoclimatic data across different continents. He also suggested that the continents had once been part of a single supercontinent called Pangea.
What was the name of the supercontinent that was hypothesis to have existed when all continents had been joined?
Pangea
What evidence did wegener gather to support his continental drift hypothesis?
Well it wasn't so much climate as the fossils that have been found. Fossils have been found in Antarctica of plants that only occur in tropical climates so at one point it must have had a tropical climate. That is the most dramatic example but there are more subtle ones that led him to believe that the continents, at one point, must have been in different locations on the Earth and then moved to where they currently are.
