Oceanic plates are thinner and found under the ocean, they are denser (3.0kgm) than continental plates and consist of basaltic rock. 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. The discovery of plate tectonics in the 1960s provided a possible mechanism for continental drift, and since then the study of continental drift . What is the Best Piece of Evidence for Plate Tectonics? One evidence of this is the existence of the same animals and plants on the different continents. First, they theorized that separate species developed identically across the far-flung continents, a notion that was highly unlikely. Continental drift theory was given by Alfred Wegener in 1915.

Glossopteris ferns had very heavy seeds that could not move by wind or drift on ocean currents. Continental drift is defined as the motion of the earth's continents over a defined period of time. By the late 1960s, several American investigators, among them Jack E. Oliver and Bryan L. Isacks, had integrated this notion of seafloor spreading with that of drifting continents and formulated the basis of plate tectonic theory.

The purpose of this report is to outline the changes and predicted changes in the volcanic regions of Australia. Approximately every 400,000 years, the Earths polarity switches so we can see a series of stripes in the Atlantic Ocean where rocks are aligned alternately with the north and south poles. Sedimentary rocks examination showed a change in climates, and the only possible explanations are continental drift or movement of the poles. Wegener suggested that when the organisms were alive the lands were joined and the organisms were living side-by-side. This cookie is set by GDPR Cookie Consent plugin.

For example, the continents of South America and Africa fit perfectly when brought together. identical rocks, mountains and structures. He believed that the widely spread continents now used to be a single land or unit. Contact Us . 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. Alfred Wegener proposed the Continental Drift Theory in 1912. Glacier grooves are the gaping trenches or landmarks carved out by movement of glacier. could scientists produce the hard evidence to support Holmes's fundamental concept. A graphic of Gondwana.

They remained in this slow phase for about 40 million years. It does not store any personal data. However, he supported his theory by explaining the earth's geologic history. What are some of the major pieces of evidence for the theory of plate tectonics? The four pieces of evidence for the continental drift include continents fitting together like a puzzle, scattering ancient fossils, rocks, mountain ranges, and the old climatic zones' locations. Sea floor spreading indicates that since the continents presently move apart, previous continental drift was possible and probable as well. 1 What evidence supports the continental drift theory? Oceanic ridges occur along some of the plate margins. 4. The possibility that they might reflect true wander of the poles was discarded, because it implies separate wanderings of many magnetic poles over the same period. What types of fossils were used as evidence for continental drift? South America and Africa contain fossils of animals found only on those two continents, with corresponding geographic ranges. Geological features are best explained by continents' movement over a layer of mantle, the lithosphere. What evidence did Wegner use to support his theory of continental drift?

Alfred Wegener proposed that the continents were once united into a single supercontinent named Pangaea, meaning all earth in ancient Greek. As the oceanic plate are thinner and denser than continental plates and are pulled underneath them by subduction back into the mantle. Glacial deposits, specifically till, of the same age and structure are found on many separate continents that would have been together in the continent of Pangaea. They based their idea of continental drift on several lines of evidence: fit of the continents, paleoclimate indicators, truncated geologic features, and fossils. 3 Which is evidence supporting the theory of continental drift? Continental drift also comes along with grave effects such as Volcanoes, Earthquakes, and Tsunamis. Impact craters have been found both on dry land and on the ocean floor. Fossil evidence for Pangaea includes the presence of similar and identical species on continents that are now great distances apart. In terms of rock composition, at locations where continents match up, the kinds of rocks on the opposite sides of the continents were of the same kind. Laurasia contained the land masses in the northern hemisphere such as North America, Europe and Asia. Subsequent plate movements averaging about 2 cm (0.8 inch) per year have taken the continents to their present position. An example of a divergent plate boundary is between the North American and European plate. According to the modern day map, these continents are far apart. What evidence did Wegener not support his hypothesis of continental drift? Theory of Plate Tectonics was established by Alfred Wegener. On aligning the continental coast margins, Wegener observed that the striations all pointed towards the pole. Not consenting or withdrawing consent, may adversely affect certain features and functions. Almost all plate movement occurs in boundaries which lie between different plates. 2.

The curves for Europe and North America, for example, are reconciled by the assumption that the latter has drifted about 30 westward relative to Europe since the Triassic Period. To support his theory Wegener pointed to matching rock formations and similar fossils in Brazil and West Africa. What fossil evidence supports the belief that all of these continents were once joined and known as Pangea? Aside from the congruency of continental shelf margins across the Atlantic, modern proponents of continental drift have amassed impressive geologic evidence to support their views. Which example is another piece of evidence? Which statement best supports the theory of continental drift? 3. For millions of years, all the land of Earth was joined together in a supercontinent, which is known as Pangaea. He provided evidence that mountain ranges occurring on opposite continents matched up pretty well when brought together. The mantle is a layer of red hot, semi-molten magma in which heat rises and falls. One of the first lines of evidence suggesting the existence of plate tectonics was the discovery of very similar fossils in rock masses separated by vast distances and by ocean expanses. The technical storage or access is necessary for the legitimate purpose of storing preferences that are not requested by the subscriber or user. Government programs to settle the land This drifting takes millions of years to complete this process. This theory was met with skepticism and was largely dismissed by the scientific community for many years. Continental drift is the suggestion that over long periods of geological time, the continents of the Earth have moved apart from each other and had once formed almost one single land mass known as Pangaea. . (Yes. Today, the theory of continental drift has been replaced by the science of plate tectonics. Molten rock material from Earths mantle rises upward to the crests, cools, and is later pushed aside by new intrusions. The shores of Red Sea exhibits evidence of having undergone lateral displacement /Sea flow spreading The remaining 16% is normal (also called baryonic) matter, comprised of every single planet, star and galaxy in the visible universe. Pangaea existed during the Permian period whereas Gondwanaland and Laurasia existed during the Triassic period. This perfect aligning of mountain ranges indicated that the continents were once together. Other examples of Fold Mountains are: The Andes, The Alps and The Rockies. Well, this claim was made in the 90s by Alfred Wegener, a German polar researcher, meteorologist and geophysicist who died in 1930. The geomorphology textbooks focusses on the detailed processes which takes places in the weathering of rocks and the transport of debris as landforms are created and destroyed. This was based on the evidence of fossils that he gathered. What does it mean that the Bible was divinely inspired? It is important to know that the following specific fossil evidence was not brought up by Wegener to support his theory. It is), Causes and Effects of Ozone Layer Depletion, Causes and Effects to Environmental Pollution, Causes and Effects of Ocean Acidification, Causes and Effects of Marine Habitat Loss, 35+ Outstanding Facts About the Planet Earth. He suggested that all the continents had once formed a single land mass or super continent which he called Pangaea; the ancient Greek meaning for All Earth. These reptiles lived in freshwater bodies such as lakes and rivers. Out of these, the cookies that are categorized as necessary are stored on your browser as they are essential for the working of basic functionalities of the website. Forces behind the drifting of continents, according to Wegener Evidence in support of Continental Drift Drawbacks of Continental Drift Theory Tectonics During WW II, it was discovered that the ocean floor had some unique relief features like ridges, trenches, seamounts, shoals etc. During the early 1960s, the American geophysicist Harry H. Hess proposed that new oceanic crust is continually generated by igneous activity at the crests of oceanic ridgessubmarine mountains that follow a sinuous course of about 65,000 km (40,000 miles) along the bottom of the major ocean basins. 2 What are the 6 pieces of evidence for the theory of continental drift? 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. Many people didn't believe him at first. Despite Wegeners effort to try to prove his theory of continental drift, it was never accepted. Scientists did not accept Wegeners theory of continental drift. Which means Antarctica must have had a much warmer climate at one point, supporting Wegners theory of Continental drift. 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. They based their idea of continental drift on several lines of evidence: fit of the continents, paleoclimate indicators, truncated geologic features, and fossils. As the divergent plates move apart and new magma rises from the mantle it will record the current alignment of the North Pole. continents look like puzzle pieces and seem to fit together. The continents shapes fit well together and some continents have the same fossils. In this essay I will describe more in-depth about the Earths dynamic structure and how plate tectonics affected biotas. In support of the continental drift theory, it was established that South Africa, India, Australia and South America all experienced glaciations at the same time. Corrections? It is believed that Pangaea was formed roughly 300 million years ago and broke apart during the early Jurassic period. He knew that plant and animal fossils as well as rock layers matched up in South America and Africa. They write new content and verify and edit content received from contributors. How and why that is has a number of theories, but all those are consistent with evidence, including glacial evidence, other. Some of the fossil evidence discovered on the continents includes mesosaurus, lystosaurus, cygnognathus and glossopteris. When this occurs, the sea floor grows wider, pushing the two continents apart. Lystrosaurus, on the other hand, was located in Africa, India, and Antarctica. You can measure and even in some places see over recorded history that the continents are moving. Many evidence supports the theory of continental drift. There are also several smaller plates such as the Scotia, Nazca and Cocos. Over time, the landmass broke and drifted away and is still drifting to this day. As they collide, the pacific plate is subducted under the continental Eurasian plate.

Another piece of evidence is that fossils of plants, animals and invertebrates have been found on separate continents. Consenting to these technologies will allow us to process data such as browsing behavior or unique IDs on this site. 3. What evidence supports the theory of ocean floor? Which of the following statements best describes the theory of continental drift? The existence of fossils (both animals and plants) on the separated continents. Wegener said that continents move around on Earth's surface and that they were once joined together as a single supercontinent. 2023 EduBirdie.com. Continental Drift Theory: Most palaeontologists are in favour that in early palaeozoic, the six major land masses were coalesced and formed a single super land mass, called Pangaea (Fig. What are the 4 pieces of evidence that support plate tectonics? Fossils are the stongest evidences of plate tectonics. Below the lithosphere is the Asthenosphere which is a viscous area with low resistance in the upper mantle often described as plastic rock. The rock formations of eastern North America Western Europe and northwestern Africa were later found to have a common origin and they overlapped in time with the presence of Gondwanaland. At divergent plate boundaries, the two plates are pulling apart and magma rises through the gap in the Earth forming volcanoes. Evidence for Continental Drift. The Fossil Record. By basing it on evidence, Wegener stated that the mesosaurus can also be found in other continents. The fossils of these organisms are found on lands that are now far apart. 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. The Himalayas. What are six pieces of evidence for the continental drift theory? In the early part of the 20th century scientists began to put together evidence that the continents could move around on Earths surface. For example fossils of Mesosaurus a freshwater reptile have been found both in Brazil and western Africa. Another indication of continental drift is tectonic activity and seafloor spreading. Westward drift of the Americas opened the Atlantic Ocean, and the Indian block drifted across the Equator to merge with Asia. What does Pangaea mean in Greek? .

If you look at the map before the continents drifted away, you find that Cygnognathus was situated in South America and Africa. Observable evolution on small timescales. Laurasia, makes up the northern continents of today. To support his theory, Wegener pointed to matching rock formations and similar fossils in Brazil and West Africa. 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. He suggested that Pangaea broke up long ago and that the continents then moved to their current positions. A. However we now know that it is not just the continents that move so a more correct term is plate tectonics . However, this theory of continental drift came to be accepted in the 90s after his death. The following piece of evidence represents matching geologic provinces in Africa and South America. One of the clues he used was the glacier. Over time the continents change position relative to one another as they move. When he brought these continents together, the glacier grooves perfectly matched up. There is variety of evidence that supports the claims that plate tectonics accounts for (1) the distribution of fossils on different continents, (2) the occurrence of earthquakes, and (3) continental and ocean floor features including mountains, volcanoes, faults, and trenches.
