What are the 3 evidence of continental drift?
What are the 3 evidence of 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.
What are some examples of evidence that suggest that some continents were once joined and have since separated?
Fossils of similar types of plants and animals in rocks of a similar age have been found on the shores of different continents, suggesting that the continents were once joined. For example, fossils of Mesosaurus, a freshwater reptile, have been found both in Brazil and western Africa.
Why was Alfred Wegener’s theory of continental drift rejected?
Wegener’s inability to provide an adequate explanation of the forces responsible for continental drift and the prevailing belief that the earth was solid and immovable resulted in the scientific dismissal of his theories.
What supports Wegener’s theory of plate tectonics?
Wegener supported his theory by demonstrating the biological and geological similarities between continents. South America and Africa contain fossils of animals found only on those two continents, with corresponding geographic ranges.
What are the 5 evidences of continental drift theory?
They based their idea of continental drift on several lines of evidence: fit of the continents, paleoclimate indicators, truncated geologic features, and fossils.
Was all the continents connected?
About 200 million years ago, all the continents on Earth were actually one huge “supercontinent” surrounded by one enormous ocean. This gigantic continent, called Pangaea , slowly broke apart and spread out to form the continents we know today. All Earth’s continents were once combined in one supercontinent, Pangaea.
How did Wegener explain why fossils of land animals were found on continents that are across oceans from one?
How did Wegener explain why fossils of land animals were found on continents that are across oceans from one another? – Animals evolved separately on each continent.
When did people begin to notice that coastlines of continents fit together like puzzle pieces?
The theory is not a new one. As early as the1500s map makers were beginning to notice that the individual continents fit together like pieces of a jigsaw puzzle. It wasn’t until 1912 that Alfred Wegener first proposed an acceptable hypothesis (continental drift) as an explanation.
Which observations supported Alfred Wegener’s theory of continental drift during his lifetime?
What are two observations that supported the theory 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.
