Continental Drift - University of Illinois Urbana-Champaign
It was no mystery that Africa and South America appear to fit together like a jigsaw puzzle. This was observed and noted as early as 1596 by Abraham Ortelius (Continental Drift). As time progressed, other forms of evidence emerged supporting that the …
Alfred Wegener - NASA Earth Observatory
The Atlantic coasts of Africa and South America appear to fit together neatly, like the pieces of a jigsaw puzzle. The same shape is also traced out by the Mid-Atlantic Ridge, shown on this map by the light-colored area (representing relatively shallow seas) between the two continents.
Continental Drift - National Geographic Society
2023年10月19日 · The east coast of South America and the west coast of Africa seem to fit together like pieces of a jigsaw puzzle, and Wegener discovered their rock layers “fit” just as clearly. South America and Africa were not the only continents with similar geology.
Piecing together the puzzle of continental drift - Encyclopedia Britannica
Looking at a map of the world, it appears that the eastern edge of South America and the western edge of Africa could fit together like interlocking puzzle pieces. Scientists have long noticed the similarity between the two coastlines, but it was not until the 20th century that evidence could support a theory that the continents were once ...
Pangea Puzzle – For Educators - Florida Museum
2023年11月8日 · Look for all of the pieces with the fossil remains of Cynognathus and put them together first (South America and Africa). Put all of the landmasses with Glossopteris and Lystrosaurus near each other. Notice how two of the continents (Africa and Antarctica) have the end regions of Lystrosaurus.
Discuss with them how Europe, Africa, South America, and North America might fit together as puzzle pieces. Discuss what might explain this fit. Point out that millions of years ago the continents were joined together in one supercontinent called Pangaea.
What is continental drift and how does it work? - Encyclopedia Britannica
NARRATOR: Looking at a map of the world, it appears that the eastern edge of South America and the western edge of Africa could fit together like interlocking puzzle pieces. Scientists think that is because they were once connected. In 1912 a scientist named Alfred Wegener introduced the idea of continental drift.
Wegener's Puzzling Continental Drift* Evidence
Hints for Solving the Puzzle. Have the students look for all the pieces with the fossil remains of Cynognathus and then put them together (South America and Africa). Then look for fossils that extend beyond the plate boundary such as the fern Glossopteris and …
The coastlines of South America and West Africa seem to match up. Scientists have found that rocks on the east coast of South America are the same as rocks found on the west coast of Africa. These rocks are different from rocks found in other places on Earth, suggesting that the continents were once connected.
Alfred Wegener and Continental Drift - Brigham Young University
If one were to place South America next to Africa, not only would the shapes match like two puzzle pieces, but the patterns of rock, minerals, and fossils would match, as well. This encouraged Wegener in his pursuit of the idea he called continental drift. He proposed that the two continents were once a single land mass that had somehow split ...
