Continental drift | Definition, Evidence, Diagram, & Facts
2024年10月24日 · Continental drift, large-scale horizontal movement 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.
Theory of Continental Drift: Causes and Evidence - Earth Eclipse
Wegener's theory of continental drift states that the existing continents of the earth were once glued together forming a super landmass. Over time, the landmass broke and drifted away and is still drifting to this day.
Continental drift - Wikipedia
The widespread distribution of Permo-Carboniferous glacial sediments in South America, Africa, Madagascar, Arabia, India, Antarctica and Australia was one of the major pieces of evidence for the theory of continental drift.
Continental Drift - National Geographic Society
2023年10月19日 · 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 Today, the theory of continental drift has been replaced by the science of plate tectonics.
2.1: Alfred Wegener’s Continental Drift Hypothesis
By the 1960s, scientists had amassed enough evidence to support the missing mechanism—namely, seafloor spreading—for Wegener’s hypothesis of continental drift to be accepted as the theory of plate tectonics.
5.1: Alfred Wegener’s Continental Drift Hypothesis
2024年8月24日 · Early Evidence for Continental Drift Hypothesis. Wegener’s first evidence was that some continents’ coastlines fit together like pieces of a jigsaw puzzle. People noticed the similarities in the coastlines of South America and Africa on the first world maps, and some suggested the continents had been ripped apart.
Continental Drift: The groundbreaking theory of moving continents
2021年12月14日 · Continental drift was a revolutionary theory explaining that continents shift position on Earth's surface. The theory was proposed by geophysicist and meteorologist Alfred Wegener in 1912, but...
5.5: Continental Drift - Geosciences LibreTexts
In the early part of the 20th century, scientists began to put together evidence that the continents could move around on Earth’s surface. 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.
Plate tectonics | Definition, Theory, Facts, & Evidence | Britannica
2024年11月20日 · Wegener presented the idea of continental drift and some of the supporting evidence in a lecture in 1912, followed by his major published work, The Origin of Continents and Oceans (1915). What is the cause of plate tectonics?
Wegener's Puzzling Continental Drift* Evidence
This lesson explores the evidence of continental drift* presented by Alfred Wegener and provides students the opportunity to complete a continental drift* puzzle exercise. *Continental drift is the term that Wegener used in 1912; today we use the term plate tectonics.
