What 3 pieces of evidence did Wegener use to prove continental drift?

What 3 pieces of evidence did Wegener use to prove continental drift?

Alfred Wegener, in the first three decades of this century, and DuToit in the 1920s and 1930s gathered evidence that the continents had moved. They based their idea of continental drift on several lines of evidence: fit of the continents, paleoclimate indicators, truncated geologic features, and fossils.

What are three pieces of evidence that Alfred Wegener used to support his continental drift hypothesis quizlet?

Terms in this set (5) The Theory of Continental Drift was proposed by Alfred Wegener in 1912. He used several pieces of evidence to support his theory including fossils, rocks, glacial markings, coal deposits and the fact that the continents fit together like a jigsaw puzzle. .

What evidence did Alfred Wegener use for his hypothesis?

Wegener found similar evidence when he discovered tropical plant fossils in the frozen region of the Arctic Circle. As Wegener collected more data, he realized the explanation that best fit all the climate, rock, and fossil observations involved moving continents.

What two pieces of evidence did Wegener discover that supported the idea of Pangaea?

Wegener concluded that South America and Africa (as well as others) had been connected to one another, possibly through land bridges, some 250 million years ago. He also believed that Pangea had lasted through most of Earth’s history.

What are 4 lines of evidence for 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 evidences 5 did Alfred Wegener support the theory of continental drift?

Wegener used fossil evidence to support his continental drift hypothesis. The fossils of these organisms are found on lands that are now far apart. Grooves and rock deposits left by ancient glaciers are found today on different continents very close to the equator. Today glaciers only form on land and nearer the poles.

Why did Alfred Wegener believe in continental drift?

Alfred Wegener first supported continental drift. Wegener’s explanation of continental drift in 1912 was that drifting occurred because of the earth’s rotation. This explanation and his theory were not widely accepted. Prior to Wegener, however, many had noted that the shapes of the continents seem to fit together,…

What was the problem with Wegeners theory of continental drift?

The main problem with Wegener’s hypothesis of Continental Drift was the lack of a mechanism. He did not have an explanation for how the continents moved. His attempt to explain it using tides only made things worse. But both Galileo and Darwin had serious flaws in their theories when they were first presented.

What did Wegener and hypothesis of continental drift propose?

Alfred Wegener proposed the theory of continental drift – the idea that the Earth’s continents move over hundreds of millions of years of geologic time – long before the idea was commonly accepted.

Is Alfred Wegener’s hypothesis true about continental drift?

Alfred Wegener’s Continental Drift Hypothesis. He analyzed either side of the Atlantic Ocean for rock type, geological structures and fossils . He noticed that there was a significant similarity between matching sides of the continents, especially in fossil plants. His hypothesis was thus strongly supported by the physical evidence, and was a pioneering attempt at a rational explanation.
