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 does the continental drift have that the continents were once connected?
Evidence for continental drift includes the fit of continents like South America and Africa, similar rock formations and mountain ranges on different continents, and the distribution of fossils that were once found on now widely separated landmasses. These pieces of evidence suggest that the continents were once connected in a single landmass called Pangaea.
What hypothesis by Alfred wegener explains why continents seem to fit togethere?
Alfred Wegener proposed the theory of continental drift, suggesting that continents were once joined together in a single supercontinent called Pangaea. Over time, the supercontinent broke apart and the continents drifted to their current positions, explaining why they seem to fit together like pieces of a puzzle.
What did the continents look like before the continental divide?
Before the continental divide, all the landmasses were connected as one supercontinent called Pangaea. Over time, the movement of tectonic plates caused the landmasses to separate and drift apart to form the continents we have today.
How does the continents moved from being part of pangaea to their current locations?
The movement of continents is known as plate tectonics. Over millions of years, the Earth's outer crust (lithosphere) is divided into large plates that float on the semi-fluid asthenosphere below. These plates drift and interact, leading to the breakup of Pangaea and the shift of continents to their current locations due to processes like seafloor spreading, subduction, and continental drift.
Pieces of evidence does NOT support the continental drift theory?
the continents fit together like a puzzle
Why does the earth not look like Pangaea now?
This is a result of continental drift, which moved the continents apart.
Why doesn't Pangaea look like that today?
Because the continents move because of the continental drift
What does NOT support the continental drift theory?
they couldn't agree on how it separated or what made it separate.
Key ideas of the Theory of Continental Drift?
The continental drift theory is the theory that once all of the continents were joined in a super-continent, which scientists call Pangaea. Over a vast period of time, the continents drifted apart to their current locations.
Why only 7 continents in the world?
Because during the continental drift, they were just well, split like that so...
What scientific evidence supports the continental drift the theory?
A scientist (can't remember his name) took pictures or models of the continents and put them together and they fit like a puzzle, so that's where continental drift came from,
Evidence for continental drift?
The existence in the fossil record of the same land species on several continents. Since these animals are not seafaring then the continents must have been connected at one time. Also continental drift is supported by vast empirical evidence.
What clue supported the continental drift theory?
The idea of continental drift theorizes Earthâ??s continental landmasses have drifted over time across the ocean bed. The initial clue behind this theory was the fact that separate continents seem to fit together like puzzle pieces.
How did Alfred wagener prove the continental drift theory?
Alfred Wagner proved the theory of Continental drift because he found fossils of the same animals and plants on different continents. he also found the same rock patterns on different continents.also if you look at a map of the world then you can fit some the continents together like a jigsaw
How do scientists gather and interpret evidence that earth is continually changing?
Alfred wegener a German geologist had an idea that the continental drift had happened. He said that the continents fitted like a puzzle piece. The name of the big he put is Pangea. This is evidence that scientists had from the continental drift.
What is the Alfred wegener known for?
he thought that the continents used to be one big continent and the plates underground broke and mad our continents todayAnother of his theories was that the continents are moving. He was ridiculed by the scientific community because they thought that the continents were always like this. Wegener's evidence for this was that matching fossils were in south America and also in Africa Other scientist reckoned it was a land bridge connecting the two continents even though there was no evidence for a land bridge. Also was the jigsaw-fit of the continentsWegener's theory is Continental drift- The Earth once had a single landmass that broke up into large pieces, which have since drifted apart.
