What are 3 pieces of evidence that support continental drift?
What are 3 pieces of evidence that support continental drift?
The four pieces of evidence for the continental drift include continents fitting together like a puzzle, scattering ancient fossils, rocks, mountain ranges, and the old climatic zones’ locations.
In what ways might the concept of continental drift be compared to a jigsaw puzzle?
They cited as evidence fossils of identical animals that had lived in both areas simultaneously hundreds of millions of years ago. The Atlantic coasts of Africa and South America appear to fit together neatly, like the pieces of a jigsaw puzzle.
What is the jigsaw theory of continental drift?
The theory of continental drift simply stated that continents drifted from one location to another over time. Wegener noticed that the coasts of South America and Africa seemed to fit together like a puzzle. Upon further investigation he noticed the following clues that he used to support his hypothesis.
What evidence do we have that the continents used to fit together like a puzzle?
Rock records show matching layers, mountain ranges and ancient basement rocks in continents that were once together. Glacial striations (scratches) and erratics (rocks moved away by glacial ice from original bedrock) correspond between continents.
What are the evidence of continental drift?
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.
How does it provide evidences for Wegener’s theory of continental drift the continental jigsaw?
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.
How is the continental jigsaw an evidence of Pangaea?
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.
What was probably the first evidence that led some to suspect the continents were once connected?
Wegener’s first piece of evidence was that the coastlines of some continents fit together like pieces of a jigsaw puzzle. People noticed the similarities in the coastlines of South America and Africa on the first world maps, and some suggested the continents had been ripped apart [3].
What is the 1st evidence of continental drift?
Early Evidence for Continental Drift Hypothesis. Figure 2.1. 2: Snider-Pellegrini’s map showing the continental fit and separation, 1858. Wegener’s first piece of evidence was that the coastlines of some continents fit together like pieces of a jigsaw puzzle.
What are Alfred Wegener’s four pieces of evidence?
Four fossil examples include: the Mesosaurus, Cynognathus, Lystrosaurus, and Glossopteris. Modern day representation of the Mesosaurus. The Mesosaurus is known to have been a type of reptile, similar to the modern crocodile, which propelled itself through water with its long hind legs and limber tail.
Which piece of evidence would best support the theory of 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.
