continental drift
Alfred Wegener proposed the hypothesis of continental drift in 1912, suggesting that the continents were once joined in a supercontinent he called Pangaea. His idea laid the groundwork for the development of the theory of plate tectonics.
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.
this supercontinent is called PANGEA. it is the greek word for "all lands".
Alfred Wegener used geological and paleontological evidence to propose the theory of continental drift. He observed similarities in rock formations, fossils, and mountain ranges on different continents that suggested they were once connected. Additionally, Wegener developed a hypothesis known as Pangaea, suggesting a supercontinent that gradually broke apart over millions of years to form the continents we see today.
The hypothesis is called continental drift, proposed by Alfred Wegener in the early 20th century. It suggests that a supercontinent called Pangaea broke apart over millions of years to form the continents as we know them today. This theory was later developed into the theory of plate tectonics to explain the movement of the Earth's lithosphere.
Alfred Wegener's hypothesis of continental drift explains that continents were once part of a single supercontinent called Pangea, which over time drifted apart to their current positions. This theory is supported by geological evidence such as the matching shapes of continents on opposite sides of the Atlantic Ocean.
The main objection to Wegener's hypothesis of continental drift was the lack of a plausible mechanism to explain how continents could move. Wegener's idea of continents plowing through solid oceanic crust was not supported by scientific knowledge at that time, leading many scientists to reject his hypothesis.

All of the continents fit together like a puzzle.
the continents were once joined together in a single landmass
Alfred Wegener proposed the continental drift hypothesis in 1912, suggesting that continents were once connected in a supercontinent called Pangaea and drifted to their current positions. Despite facing skepticism initially, his ideas laid the foundation for the theory of plate tectonics, which explains the movement of Earth's lithosphere.
He could not explain how or why the continents moved.
Major rivers on different continents match
because he didn't know how the tectonic plates/continents moved
Alfred Wegener's hypothesis of continental drift proposed that the Earth's continents were once joined together in a single supercontinent called Pangaea. He suggested that over time, Pangaea broke apart and the continents drifted to their current positions. Wegener supported this theory with evidence like matching coastlines, similar rock formations, and fossil distribution across continents.
They all fit together like a puzzle.
provide a plausible mechanism for how the continents could move. Additionally, his idea was met with skepticism because it contradicted the widely accepted belief at the time that the continents were fixed in place. The lack of supporting geological and geophysical evidence also contributed to the rejection of Wegener's hypothesis.
