What is coastline matching evidence?
Coastline Matching The similarity of coastlines for different continents suggests that they may once have been connected.
But the fact that they were separated by sometimes thousands of miles suggested continental drift or plate tectonics ..
What is the best evidence of plate tectonics?
Modern continents hold clues to their distant past. Evidence from fossils, glaciers, and complementary coastlines helps reveal how the plates once fit together. Fossils tell us when and where plants and animals once existed.
What are 5 pieces of evidence that support continental drift?
In the early part of the 20th century, scientists began to put together evidence that the continents could move around on Earth’s surface. The evidence for continental drift included the fit of the continents; the distribution of ancient fossils, rocks, and mountain ranges; and the locations of ancient climatic zones.
What is the evidence for Pangea?
Evidence of existence Fossil evidence for Pangaea includes the presence of similar and identical species on continents that are now great distances apart.
Why do the continents fit together like a puzzle?
Ever notice that the earth’s continents are somewhat fit each other along continental margins( edges), it is because it was once a supercontinent called PANGEA. Pangaea existed 200 million years ago and completely underwent continental drift 50 million years ago. …
What are the 4 evidence of continental drift?
They based their idea of continental drift on several lines of evidence: fit of the continents, paleoclimate indicators, truncated geologic features, and fossils.
Did the edge of the continents fit together?
If the continental boundaries of North America, Europe, and South America are defined as the edge of the continental shelf, then those continents also fit together very well. … Evidence for “polar wandering” could be better explained with stationary poles and drifting continents.
Which continent moves the fastest Where will it be in 50 000 years?
Australia has tended to move particularly fast due to its unique geology. Corrections have been made to its latitude and longitude four times over the past 50 years, the Times reports. The last adjustment there, in 1994, was about 656 feet.
What are 6 pieces of evidence that support continental drift?
What are six pieces of evidence for the continental drift theory? Reptile Fossils- dinosaurs couldn’t have swam across a vast ocean. Plant Fossils- all these regions were once connected and had similar climates. Tropical plants found in Arctic- tropical plants can’t grow in cold climates.
How can fossil be used as evidence for continental drift?
There are many examples of fossils found on separate continents and nowhere else, suggesting the continents were once joined. If Continental Drift had not occurred, the alternative explanations would be: They swam to the other continent/s in breeding pairs to establish a second population. …
What are the 3 theories of plate tectonics?
Plates interact at three types of plate boundaries: divergent, convergent and transform. Most of the Earth’s geologic activity takes place at plate boundaries. At a divergent boundary, volcanic activity produces a mid ocean ridge and small earthquakes.
Which continents seem to fit together?
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.
