What was the observation that interested Sir Francis Bacon regarding continental drift?
In 1620, Sir Francis Bacon observed similarities of coasts of Africa and South America. In 1799, Alexander Von Humbolt, German explorer and naturalist, observed the similarities in the geology and features of the west coast of Africa and east coast of South America.
What type of reptiles also helped to support the idea of continental drift?
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.
What are the 4 evidence for Pangea?
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 continental theory was first proposed by Sir Francis Bacon?
Francis Bacon played an indirect role in the contribution to plate tectonic theory and solid Earth geophysics, but was influential to all in the scientific community. Francis Bacon created the Scientific Method, also known as the Bacon Method. The Great Instauration was divided into 6 parts: 1.
How did Oceanography play an important role in proving continental drift theory?
In 1915, Wegener proposed his continental drift theory. He said that the continents floated atop the mantle-a heavier, denser layer of rocks deep within the earth. This evidence led early marine geologists to deduce that the mid-ocean ridges were formed by seafloor volcanoes.
What are the two theories that support plate movement?
Like the scientists before us, we will now merge the ideas of continental drift and seafloor spreading into the theory of plate tectonics.
Do the continents fit together?
The shapes of continents fit together like a puzzle. Just look at the east coast of South America and the west coast of Africa—it’s almost a perfect fit! Identical rocks have been found on different continents. These rocks formed millions of years ago, before the continents separated.
Why was the Wegener’s theory forgotten?
Why was Wegener’s theory forgotten? He could not explain how the continents could move. Why is Earth not growing in spite of sea floor spreading? because of subduction the Pacific Ocean.
Why was Alfred Wegener’s hypothesis rejected?
The main reason that Wegener’s hypothesis was not accepted was because he suggested no mechanism for moving the continents. He thought the force of Earth’s spin was sufficient to cause continents to move, but geologists knew that rocks are too strong for this to be true.
What was the main reason why Alfred Wegener’s theory about the movement of the continents was dismissed in 1912?
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.
