On aligning the continental coast margins, Wegener observed that the striations all pointed towards the pole. One of the strongest pieces of evidence is Continental break up/fit, this is the idea that the continents were once joined together. Also, fitting the Americas with the continents across the Atlantic brings together similar kinds of rocks, fossils, and geologic structures. He explained how the continents moved Question 9 30 seconds Q. Pangaea has not been the only supercontinent on Earth. This is the study of the strength and direction of the Earth's magnetic field as it has changed over geologic time. According to National Geographic, sea floor spreading and plate tectonics indicate that the continents do move or shift, which supports continental drift theory. Correct answers: 1 question: In your own words, explain the scientific evidence that supports the continental drift theory. Evidence supporting the continental drift theory. The first truly detailed and comprehensive theory of continental drift was proposed in 1912 by Alfred Wegener, a German meteorologist. answer choices He had no good evidence. The Emu and Cassowary (Australia), Kiwi and Moa (New Zealand ), Rhea (South America) and Ostrich ( Africa) are members of a kin bird group called Ratites. Through the theory of continental drift, humans have been able to figure out how the earths crust moves and the causes of volcanoes, earthquakes, oceanic trenches, formation of mountain ranges and other geological occurrences. Studies by Runcorn of the remanent magnetism in suitable rocks of different ages from Europe produced a polar wandering curve indicating that the magnetic poles were in different places at different times. It was hard for Wegner to back his theory as he was unable to explain how the continents moved. Sea floor spreading further supports the continental drift theory. Despite being dismissed at first, the theory gained steam in the 1950s and 1960s as new data began to support the idea of continental drift. Where the plates collide they form fold mountains e.g. Evidence of glaciers in unexpected places. fossil. Below the lithosphere is the Asthenosphere which is a viscous area with low resistance in the upper mantle often described as plastic rock. Continental drift is a theory originally proposed by Alfred Wegener, who believed the continents were once one large continent known as Pangaea that later separated into several continents.

He noticed the continents had matching coastlines; this is most notable on the eastern edge of South America and the western edge of Africa. As we travel further from the mid Atlantic ridge we can see the alignment changing which proves the continents have been moving away from each other. Where this is the case, the lithospheric plates separate, and the upwelling mantle material forms new ocean floor along the trailing edges. Wegener found coal in Greenland and claimed that this supported his ideas about continental drift. They based their idea of continental drift on several lines of evidence: fit of the continents, paleoclimate indicators, truncated geologic features, and fossils. Wegener suggested that perhaps the rotation of the Earth caused the continents to shift towards and apart from each other. Apparent Fit. Embryos of four different species.

Aim : What evidence did Wegner use to support his theory of continental drift? As the plates move away from the flanks of the ridges, they carry the continents with them. So, his theory is proved by the fact that the freshwater reptiles could not swim across the ocean waters, hence, their distribution on every continent. This was based on the evidence of fossils that he gathered. More evidence was needed, and it came from the Earth's magnetism. Fossils of similar types of plants and animals in rocks of a similar age have been found on the shores of different continents, suggesting that the continents were once joined.

By basing it on evidence, Wegener stated that the mesosaurus can also be found in other continents. He called his hypothesis continental drift. One of the reasons that dark matter has arisen as a theory is the fact that when we observe certain galaxies, they have much more kinetic energy then the masses in them would suggest, therefore, a separate force must be at play.
