Alfred Wegener Noticed:
1. Landforms like coal saturations or mountain ranges on either side of the ocean.
2. Fossil record. Fossils of identical plants and animals found in Africa and south america.
3. Aincient striations (grooves and scratches made by ice ages) identical on either side of the ocean.

What are three kinds of evidence that support wegener's theory?
The pieces of evidence Alfred Wegener used to support his theory about continental drift were; Puzzle Fit, Fossil evidence from animals that were once on the same continent, geologic evidence like mountain chains that were connected and now split apart, and ice sheets. Thank you for reading this article and I hoped it answered your question!
Who proposed the theory of continental drift when?
Alfred Wegener proposed it. He noticed similarities in fossils in places like Western Africa and Eastern South America. Then, he noted that those two continents could fit together, like puzzle pieces. He proposed that they used to be joined, and although his theory was not taken seriously at first, we now know he was correct.
Does sediment build up at the continental shelf?
The continental shelves were formed millions of years ago, when most of the land on the Earth was compacted into one huge landmass. After some time, this landmass began to break into smaller pieces, which became the continental shelves. Then they drifted farther and farther apart and appear where they are today.
What three pieces of evidence for Wegener's theory came from the sea floor?
seafloor spreading, age of the sea floor and ocean trenches.
What evidence did wegner have for continental drift theory?
Actually there is a lot of evidence that supported his evidence the big one was fossils of animals on distant continents and plants for example Glossopteris was one the strange reasons that Alfred was more than ever to prove his point.Edit:Alfred Wegener proposed that, using 19th century longitude determinations, Greenland had moved 1 mile away from Europe. However, this conclusion ended up being false due to false calculations. Still, Wegener discovered that every year San Diego moved 6 feet closer to Shanghai while Washington D.C. and Paris got 15 feet closer. In addition, Alfred Wegener discovered that related species, too small to swim across the ocean, were found on different continental plates, as well as similar fossils.Alfred Wegener's theory was rejected at first, however, because he was unable to explain the reason why the plates moved. Later, Arthur Holmes published his theory of thermal convection being the the thing that drove the plates apart. He also noted that the continents didn't "move" but were "carried" by larger pieces of the Earth's crust. Discoveries of the Mid-Ocean Ridge in addition to Harry Hess's work adds onto this theory of Wegener's.As this theory is the most complete theory concerning global dynamics, the roots of such lie in the curiosity and work of Alfred Wegener.
What were the 3 types of evidence the Alfred Wegener used to support his theory of Continental Drift?
Alfred Wegener used fossil evidence, geological evidence, and paleoclimatic evidence to support his theory of Continental Drift. Fossils of the same species found on different continents, similar rock formations and mountain ranges across continents, and matching ancient climate patterns were key pieces of evidence that he presented.
What evidence of land feautures did Alfred wegener use?
Alfred Wegener used various pieces of evidence to support his theory of continental drift, including the fit of the continents, rock and fossil similarities across continents, glacial evidence, and similar geological features on different continents.
What are 4 pieces of evidence4 alferd wegner used to support this theory?
Four pieces of evidence used by Alfred Wegener to support his theory of continental drift were the fit of the continents, matching geological formations across continents, similar fossil distributions, and glacial evidence in tropical regions.
What 3 pieces of evidence did Alfred Wegener use to support his theory of continental drift?
he used fossils, glacial indentations, and different types of rock.
What evidence did Wenger gather to support his continental drift hypothosis?
Alfred Wegener gathered several pieces of evidence to support his continental drift hypothesis, including the fit of the continents, matching geological formations across different continents, similarities in fossil distributions, and paleoclimatic evidence such as glacial deposits and coal seams in regions that are now separated by oceans. These pieces of evidence suggested that the continents were once connected and have since drifted apart.
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.
What evidence was used to support continental drift?
Evidence supporting continental drift includes the fit of the continents like pieces of a giant jigsaw puzzle, matching geological features across different continents, similarities in rock formations and mountain chains, distribution of fossils across continents, and the pattern of magnetic stripes on the ocean floor that support seafloor spreading. These pieces of evidence collectively support the theory of continental drift proposed by Alfred Wegener.
What evidence did Alfred wanger use to support his theory of contnetal drift?
Alfred Wegener used several lines of evidence to support his theory of continental drift. This included the fit of the continents like a jigsaw puzzle, similarities in rock formations and mountain ranges across different continents, matching fossils on separate continents, and paleoclimatic evidence such as glacial striations in tropical regions. These pieces of evidence led Wegener to propose the theory of continental drift in the early 20th century.
What evidence did Alfred Wegener have that supported his idea of continental drift?
South America and Africa fit together like puzzle pieces.
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.
True or false wegener knew that continental drift explained fossils of tropical plants?
True. Alfred Wegener, the scientist who proposed the theory of continental drift, used the distribution of fossils of tropical plants across continents as evidence to support his idea that the continents were once connected. This was one of the key pieces of evidence Wegener used to support his theory.
What other evidence is there to support Alfred Wegener's theory of continental drift?
Other evidence to support Alfred Wegener's theory of continental drift includes matching geological formations and rock types on different continents, similar fossil collections on continents that are now separated by oceans, and the fit of the continents' coastlines like pieces of a jigsaw puzzle. Additionally, the discovery of mid-ocean ridges and the study of paleomagnetism has further bolstered the theory.
