What are the evidence 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.
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.
Why did scientists reject Wegener’s idea of continental drift?
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.
Why did scientists reject Wegener’s theory?
Wegener believed that continental drift explained fossils of tropical plants found in places that today have a polar climate. Most scientists rejected Wegener’s theory because he could not explain the force that pushes or pulls the continents.
What did Alfred Wegener believe?
His widely accepted theory of land displacement holds that Earth’s continents have been in motion throughout geologic time. Wegener believe that there was once a single supercontinent, which he called Pangea (or Pangaea). He said that Pangea broke apart millions of years ago to form two large continents.
How does continental drift affect climate?
This drift also had an impact on the climate because it changed the physical features of the landmass, their position and the position of water bodies. The separation of the landmasses changed the flow of ocean currents and winds, which affected the climate.
