Oct 19, 2023 · Vocabulary. Continental drift describes one of the earliest ways geologists thought continents moved over time. Today, the theory of continental drift has been replaced by the science of plate tectonics. The theory of continental drift is most associated with the scientist Alfred Wegener. In the early 20th century, Wegener published a paper ...
One piece of evidence Wegener provided was paleoclimatic indicators that linked South America and Africa (Plate Tectonics: Continental Drift). He noted that glacial, tropical rain forests, and desert deposits were aligned when the continents were placed together (Plate Tectonics: Continental Drift).
Apr 5, 2024 · continental drift, large-scale horizontal movements of continents relative to one another and to the ocean basins during one or more episodes of geologic time. This concept was an important precursor to the development of the theory of plate tectonics, which incorporates it. The idea of a large-scale displacement of continents has a long history.

Wegener said that continents move around on Earth’s surface and that they were once joined together as a single supercontinent. While Wegener was alive, scientists did not believe that the continents could move.Find a map of the continents and cut each one out. Better yet, use a map where the edges of the continents show the continental shelf.
After reviewing the scientific literature, he published a hypothesis stating the continents were originally connected and then drifted apart. While he did not have the precise mechanism worked out, his hypothesis was backed up by a long list of evidence. Figure 2.1.1 2.1. 1: Wegener later in his life, ca. 1924-1930.
Feb 19, 2022 · The occurrence of glacial features (Figure 15.1.7 15.1. 7) in the geologic record of South America, Africa, India ,and Australia provides further evidence for the notion of continental drift. Glaciers affected all or part of these continents at the same time in Earth history.
What is the evidence for continental drift? Wegener’s evidence for continental drift was that: the same types of fossilised plants and animals are found in South America and Africa; the west coast of South America fits the east coast of Africa like a jigsaw puzzle; rock formations and mountain chains match in South America and Africa;
