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 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.

Pieces of evidence does NOT support the continental drift theory?
the continents fit together like a puzzle
What evidence did Alfred Wegener have that supported his idea of continental drift?
South America and Africa fit together like puzzle pieces.
What are pieces of evidence that support the idea of Pangaea?
Continental Fit, Fossil Evidence and Sea floor Spreading. I just did this in science a month ago. :)
What did Alfred Weneger try to prove?
Alfred Weneger was trying to prove his theory of Continental Drift. Many other scientists before him had the same theory, but they never could prove it. He had five pieces of evidence.
Which one of the following pieces of evidence did Wegener use to support his theory of continental drift?
the age of the rocks in the sea floor is all the same
What theory did Alfred wegner introduce?
Alfred Wegener's theory was known as the theory of continental drift.
What are 3 pieces of evidence that support the idea of continental drift?
the flora and fauna found in the continents the shape of the Africa continent and the American continent the continued separation of the continents
