What three arguments did geologists use to diprove Alfred Wegeners theory?

These were (1) the fact that the coastlines of Europe, Africa, and the Americas fit together like a jigsaw puzzle, (2) the fact that some geological formation (mainly in Africa) seemed to continue across into the Americas, (3) the fact that some fossil species seemed to be found in corresponding places on both sides of ...

What were the three 3 pieces of evidence in support of Wegener's theory?

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 evidence supports the theory of Alfred Wegener?

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 is Alfred Wegener theory?

In the early 20th century, Wegener published a paper explaining his theory that the continental landmasses were “drifting” across the Earth, sometimes plowing through oceans and into each other. He called this movement continental drift.

What are the 4 pieces 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 evidence did Wegener rely on in the formulation of his theory of continental drift What evidence did he lack?

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.

Who were the two scientists that brought forth supporting evidence to Wegener's theory and what was their evidence?

(A: Author Holmes and Harry Hess were the two scientists that brought forth evidence. They had a theory that the Earths mantle moved the continents.

What was the main reason Wegener's continental drift hypothesis was 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.

How did Alfred Wegener contribute to the theory of plate tectonics?

Plate tectonic theory had its beginnings in 1915 when Alfred Wegener proposed his theory of "continental drift." Wegener proposed that the continents plowed through crust of ocean basins, which would explain why the outlines of many coastlines (like South America and Africa) look like they fit together like a puzzle.

What are 3 types of evidence for seafloor spreading?

Several types of evidence from the oceans supported Hess's theory of sea-floor spreading-evidence from molten material, magnetic stripes, and drilling samples.

Why was mosasaurus a significant piece of evidence that supports plate movement?

Mesosaurus was significant in providing evidence for the theory of continental drift, because its remains were found in southern Africa, Whitehill Formation, and eastern South America (Melo Formation, Uruguay and Irati Formation, Brazil), two widely separated regions.

What does plate tectonic theory predict about the distribution of earthquakes and volcanoes?

What does plate tectonic theory predict about the distribution of volcanoes and earthquakes? They should be evenly distributed throughout the earth. They should occur primarily along plate boundaries.

What geological evidence supports the idea of continental drift quizlet?

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. .

When did Alfred Wegener make his theory?

Wegener first presented his theory in lectures in 1912 and published it in full in 1915 in his most important work, Die Entstehung der Kontinente und Ozeane (The Origin of Continents and Oceans).

What are the 3 causes of plate movement?

Lesson Summary

Additional mechanisms that may aid in plates moving involve ridge push, slab pull and trench suction. In ridge push and slab pull, gravity is acting on the plate to cause the movement.

How did scientists prove the theory of seafloor spreading?

The age, density, and thickness of oceanic crust increases with distance from the mid-ocean ridge. The magnetism of mid-ocean ridges helped scientists first identify the process of seafloor spreading in the early 20th century.

What theory unified the theories of continental drift and seafloor spreading?

Tuzo Wilson, combined the continental drift and seafloor spreading hypotheses to propose the theory of plate tectonics. Tuzo said that Earth's crust, or lithosphere, was divided into large, rigid pieces called plates.
