Which of the following explains how the map shows evidence for the existence of Pangaea? Some 50 years later, Antonio Snider-Pellegrini, a French scientist, argued that the presence of identical fossil plants in both North American and European coal deposits could be explained if the two continents had formerly been connected, a relationship otherwise difficult to account for. Evidence Alfred Wegener collected diverse pieces of evidence to support his theory, including geological "fit" and fossil evidence. 1 What evidence supports the continental drift theory?

Watch Earth's continents move, from 650 million years ago to 250 million years in the future 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. The technical storage or access that is used exclusively for anonymous statistical purposes. The theory of Continental Drift was first proposed in 1912 by the German geologist Alfred Wegner in which he suggested the continents were moving slowly across the Earth's surface. Fossils tell us when and where plants and animals once existed. As the plates pulled apart from each other millions of years ago it caused earthquakes which led to magma rising from the mantle and erupting through the crust forming the Mid Atlantic Ridge as it solidified, this is called sea floor spreading as it is an example of two oceanic plates pulling away from each other. Which of the following statements best describes the theory of continental drift? Where the plates collide they form fold mountains e.g. However, these different paths are reconciled by joining the continents in the manner proposed by Wegener.

There are two varieties of tectonic plates: Oceanic plates and Continental plates. What are the three pieces of evidence for continental drift? If you take a look at the map before the continents drifted away, you find that Mesosaurus is located in the southern parts of Africa and North America. Geological fit evidence is the matching of large-scale geological features on different continents. The distribution of these reptiles in different continents proves that these separate land masses were once together before splitting. What is continental drift theory explain with evidence?

Destruction happens when one plate moves below the other at convergent boundaries. Wegener specifically used rock composition and mountain ranges to provide evidence of continental drift. Continental drift describes one of the earliest ways geologists thought continents moved over time. They based their idea of continental drift on several lines of evidence: fit of the continents, paleoclimate indicators, truncated geologic features, and fossils. However, this theory of continental drift came to be accepted in the 90s after his death. Fossils of creatures and plants discovered on different continents helped to him push his case that the continents were once locked together before breaking up and drifting away. Wegener suggested that perhaps the rotation of the Earth caused the continents to shift towards and apart from each other. The advancement and knowledge on the plate tectonics theory was a very important asset to biogeography, it provided a foundation for our understanding of our ever-evolving planet.

Despite Wegeners effort to try to prove his theory of continental drift, it was never accepted. 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. Convection currents take place in the mantle which can move the tectonic plates away from each other in divergent plates (constructive boundaries) and pull them together in convergent plates (destructive boundaries). Wegener said that continents move around on Earth's surface and that they were once joined together as a single supercontinent. This perfect aligning of mountain ranges indicated that the continents were once together. Mountains created by colliding continents. Rock Correlation.

Bringing together a large mass of geologic and paleontological data, Wegener postulated that throughout most of geologic time there was only one continent, which he called Pangea. It Doesnt), Is Galvanized Steel Conductive? If these continents were once united around the south polar region, this glaciation would become explicable as a unified sequence of events in time and space.

The fact that the seeds would have been unable to be blown or floated to these continents proves that these continents were once together. Finding identical or similar fossils in areas separated by vast distances were some of the first clues that scientists used to reconstruct past plate movement. 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. South America and Africa contain fossils of animals found only on those two continents, with corresponding geographic ranges.

What evidence did Wegner use to support his theory of continental drift? Plant Fossils- all these regions were once connected and had similar climates. On the other hand, tectonic movement destroys crust during interaction of the plates. Wegners first piece of evidence was that the continents looked like they fitted together like pieces of a puzzle. What did Alfred Wegener discover?
