What evidence did Alfred Wegener have that all of the continents were once connected together?

Wegener then assembled an impressive amount of evidence to show that Earth’s continents were once connected in a single supercontinent. Wegener knew that fossil plants and animals such as mesosaurs, a freshwater reptile found only South America and Africa during the Permian period, could be found on many continents.

What is the evidence that Alfred Wegener used to make the claim that the continents of Africa and South America were once joined?

There are various examples of fossils found on separate continents and in no other regions. This indicates that these continents had to be once joined together because the extensive oceans between these land masses act as a type of barrier for fossil transfer.

What evidence suggest that continents were once joined?

fossils
There are many examples of fossils found on separate continents and nowhere else, suggesting the continents were once joined. If Continental Drift had not occurred, the alternative explanations would be: The species evolved independently on separate continents – contradicting Darwin’s theory of evolution.

What are the 4 evidences 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 the evidence gathered by Alfred?

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.

How did Alfred Wegener explain the movement of continents?

The theory of continental drift is most associated with the scientist Alfred Wegener. 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.

What 3 pieces of evidence did Alfred Wegener cite to propose his theory?

What did Alfred Wegener suggest?

The theory of continental drift is most associated with the scientist Alfred Wegener. He called this movement continental drift. Pangaea. Wegener was convinced that all of Earth’s continents were once part of an enormous, single landmass called Pangaea.

How did Alfred Wegener discover Continental Drift?

Fossils of similar organisms across widely disparate continents encouraged the revolutionary theory of continental drift. He called this movement continental drift. Pangaea. Wegener was convinced that all of Earth’s continents were once part of an enormous, single landmass called Pangaea.

What is Wegener’s theory of Continental Drift Class 7?

He proposed that millions of years ago, all landmasses were joined together into a super continent, called Pangaea. He suggested that the Pangaea broke and there was a horizontal displacement of the continents. This is called Wegener’s Theory of Continental Drift.
