The theory of continental drift was proposed at the beginning of the last century by German scientist Alfred Wegener. Before Wegener developed his theory, it was thought that mountains formed. CONTINENTAL DRIFT THEORY Continental drift is the hypothesis that all the continents had once been joined together in a single landmass. Alfred Wegener named this supercontinent Pangaea. Pangaea existed about 300 million years ago. This was the time when reptiles and winged insects first appeared The theory of continental drift is most associated with the scientist Alfred Wegener. In the early 20th century, Wegener published a paper explaining his theory that the continental landmasses were drifting across the Earth, sometimes plowing through oceans and into each other. He called this movement continental drift While in Europe and North America Wegener's ideas were being attacked, in the southern hemisphere some of his staunchest supporters were collecting data to support the theory of continental drift. One, a South African named Alexander duToit traveled to Brazil, Uruguay, and Argentina where he found remarkable similarities in fossils and strata.

Mesosaurus - small fresh water reptile. Glossopteris - plant remains found in South America, Australia, Asia and Africa
  3. Continental drift was a theory that explained how continents shift position on Earth's surface. Set forth in 1912 by Alfred Wegener, a geophysicist and meteorologist, continental drift also explained why look-alike animal and plant fossils, and similar rock formations, are found on different continents and why many of the continents appear to fit together like puzzle pieces into one super.
  4. The idea of continental drift was not accepted easily by the scientific establishment. Even though Wegener assembled many interlocking pieces of evidence to support his ideas, they were so radical that he was often ridiculed. Eventually, however, scientists made more observations, assembling the modern theory of plate tectonics

Continental Drift. Alfred Wegener, in the first three decades of this century, and DuToit in the 1920s and 1930s gathered evidence that the continents had moved. They based their idea of continental drift on several lines of evidence: fit of the continents, paleoclimate indicators, truncated geologic features, and fossils Continental drift was a theory that explained how continents shift position on Earth's surface. Set forth in 1912 by Alfred Wegener, a geophysicist and meteorologist, continental drift also. Continental drift was a revolutionary scientific theory developed in the years 1908-1912 by Alfred Wegener (1880-1930), a German meteorologist, climatologist, and geophysicist, that put forth the hypothesis that the continents had all originally been a part of one enormous landmass or supercontinent about 240 million years ago before breaking apart and drifting to their current locations Rock clues support Wegners theory of continental drift and Pangaea because when India hit Eurasia the Himalayas formed and that is where Mt Everest is today

The Continental Drift theory is a theory because there is no evidence to support it. Alfred Wegener developed the Continental Drift theory in the 1800's. Why did most scientist reject Wegener. 1. Explain how Wegener used climate clues to support his hypothesis of continental drift. 2. Describe how rock clues were used to support the hypothesis of continental drift. 3. Summarize the ways that fossils helped support the hypothesis of continental drift. 4. Think Critically SECTION 1 Continental Drift The actual connection between the continental fit (the idea that continents fit together like the pieces of a jigsaw puzzle) was first proposed in 1858 by Antonio Snider-Pellegrini (1802-1885), Other scientists mentioned this idea for years afterward, but it was not until 1912 that German meteorologist and geologist Alfred Wegener (1880-1930) expanded the theory, suggesting that the continents. The diagram shows the break-up of the super-continent Pangaea, which figured prominently in the theory of continental drift — the forerunner to the theory of plate tectonics. Wegener also noticed a link between the rock types and geological structures that were seen to be similar on the two sides of the Atlantic

  1. The idea that continental drift has taken place came up primarily because of study of fossils discovered from different corners of earth. The word 'fossil' was coined more than 500 years ago, by German scientist Georgius Agricola, though records describing fossils are much older. It actually means 'having been dug up' in its original latin form

  4. 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. One indication of this possibility is the appearance of the western African and eastern South American coasts, which look like two interlocking jigsaw.
  5. Evidence to Prove That Pangaea had Existed / Evidence of Continental Drift. Alfred Wegener brought together several lines of evidence to support his theory of continental drift. One is quite simple i.e. the continents look like they could fit together much like a puzzle pieces that have been drifted apart
  6. Wegener's theory Wegener used geologic, fossil, and glacial evidence from opposite sides of the Atlantic Ocean to support his theory of continental drift. For example, he said that there were geological similarities between the Appalachian Mountains in North America, and the Scottish Highlands

Evidence for continental drift. answer choices. warm temperature fossils found in areas that are now cold. continents move on conveyor belts. animals swim to other continents. glaciers are only found in cold areas Rock Clues Some of the evidence used by Wegener to support his idea of continental drift came from rock formations on different continents. The rock formations and mountain ranges seemed to have formed in the same way at the same time. Today geologists know that there were large-scale volcanic eruption

Kennedy Clan Science: Clues for continental Drif

Wegener used fossil evidence to support his continental drift hypothesis. Grooves and rock deposits left by ancient glaciers are found today on different continents very close to the equator. This would indicate that the glaciers either formed in the middle of the ocean and/or covered most of the Earth Theory Not Proven: Although all of the continents could fit together like a puzzle, this is simply not enough evidence for such a large theory of science. Wegener's theory of continental drift could not be taken seriously because he did not present it as a proven theory, nor did he have factual evidence that clearly stated why his theory could be true

From the mid-19th century, fossils were used as evidence for continental drift - but mainstream scientists didn't buy it until the 1950s. Fossil finds pointed the way towards the theory of. Ungraded. 30 seconds. Report an issue. Q. Most geologists rejected Wegener's idea of Continental Drift because _________. answer choices. He used too many pieces of evidence to support the idea. He wanted to know what Earth looked like millions of years ago, which is impossible Cynognathus and Lystrosaurus were land reptiles and were unable to swim; Figure 3. Wegener used fossil evidence to support his continental drift hypothesis. The fossils of these organisms are found on lands that are now far apart. Grooves and rock deposits left by ancient glaciers are found today on different continents very close to the equator Much of the resistance to Wegener's continental drift theory came about because of how he suggested the continents once fit together. Wegener used fossil patterns to help shape the map of Pangaea as he saw it. This meant that Antarctica would be used as the root continent and the others would be formed around it

The relative movement of the continents is explained by modern theories of plate tectonics.These theories describe the processes by which lithospheric plates — of which the visible continents are a part — move over the asthenosphere (the molten, ductile, upper. The name Pangea comes from an ancient Greek word meaning all lands. This term was first used in the early 20th century when Alfred Wegener noticed that the Earth's continents seemed to fit together like a jigsaw puzzle. He later developed the theory of continental drift to explain the shapes and positions of continents and coined the title Pangea at a symposium in 1927 on the topic The second puzzle will have clues on each piece that will help the students. These clues relate to how Wegener discovered the possibility of a super-continent. WATCH IT! At this station, students will be watching a short SciShow video explaining who Alfred Wegener was and what his continental drift theory is Clues to Earth's Past 1.

Wegener's idea was thought to be true right away. False True 3. Which of these did not support Wegener's theory of continental drift

Alfred Wegener gave many facts that help prove his Continental Drift theory. Wegener's supporting facts include fossil evidence, land features, climate evidence, and sea floor spreading. In the beginning of Wegener's research to prove his Continental Drift theory, he found clues from fossil evidence from millions of years ago Plate Tectonics and Continental Drift (Infographic) In the 20th century, researchers realized that the Earth's crust is not one piece, but is made up of many huge tectonic plates upon which the.

This hypothesis is similar to Ortelius. He proved this theory by using fossil clues, climate clues, and rock clues. But even with evidence, the science community did not accept his findings as Wegener's theory had flaws. This included the failure to answer the mechanisms and forces in order for the continents to go through the ocean A handful promoted the notion that the continents had moved (continental drift), but they were accused by the majority of indulging in pseudo-scientific fantasy. Today, that opinion has reversed—plate tectonics, incorporating continental drift, is the ruling theory. Interestingly, it was a creationist, Antonio Snider, who in 1859 first. OVERVIEW Continental drift, in the context of the modern theory of plate tectonics, is explained by the movement of lithospheric plates over the asthenosphere (the molten, ductile, upper portion of the Earth's mantle). Precisely used, the term continental drift is actually rooted in antiquated concepts regarding the structure of the Earth

Why is Continental Drift important? 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 Theory of Plate Tectonics. When the concept of seafloor spreading came along, scientists recognized that it was the mechanism to explain how continents could move around Earth's surface. Like the scientists before us, we will now merge the ideas of continental drift and seafloor spreading into the theory of plate tectonics Continental drift is an observation of the theory of plate tectonics. So the answer is, it is considered a theory. Plate tectonics - Wikipedia Plate tectonics (from the Late Latin tectonicus, from the Greek: τεκτονικός pertaining to building) [1.. What were Wegener's ideas about continental drift initially rejected? How did Wegener use climate clues to support his hypothesis? What rock clues did Wegener use to support his hypothesis? In what ways do fossils help support the hypothesis? Why would you see similar rocks and rock structures on two landmasses that were connected at one time

The presence of the same rock types is another form of evidence. Ask students if they can think of other types of evidence to search for that might be useful in solving their puzzle. Have students use Wegner's Evidence for Continental Drift to write a paragraph to explain what their map shows about the Earth 290 million years ago However, in the 1950s, evidence started to trickle in that made continental drift a more viable idea. 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 Essay On Wegener's Theory Of Continental Drift. Survey, I think that you should accept Alfred Wegener's Theory of Continental Drift. There is a large amount of realistic evidence to prove that this theory did occur. Wegener's theory is that all seven continents were once joined into a supercontinent called Pangaea 8th Grade Integrated Science Chapter 14 Lesson 1 on the Continental Drift Hypothesis. This is a short introduction to Alfred Weger and the current evidence used to support his theory. There is a short explanation of the fossil and rock evidence found. *This outline follows the Chapter 14.1 presentation slides..

Theory of Continental Drift: Causes and Evidence Earth

Continental Drift and Plate Tectonics Continental Drift. Today, most people know that landmasses on Earth move around, but people haven't always believed this. It wasn't until the early 20th century that German scientist Alfred Wegener put forth the idea that the Earth's continents were drifting. He called this movement Continental Drift. of his theory. However, since that time researchers have enough proof that Wegener's theory is now widely accepted as accurate. Among the pieces of evidence supporting the theory of continental drift are the puzzle-like fit of the continents, fossil clues, climate clues, and rock clues. Fossils of the same animal,

The other answers are wrong because those were not the reasons why the scientific establishment rejected continental drift. Become a member and unlock all Study Answers Try it risk-free for 30 day Together, these observations were consistent with a new theory proposed by researchers who built on Wegener's original idea of continental drift—the theory of plate tectonics. According to this theory, Earth's crust is broken into roughly 20 sections called tectonic plates on which the continents ride Questions; science. the continental drift theory was first brought to attention by Alfred Wegener, And some of the theories that he had was that the edges of the continents perfectly matches with one another, supporting that the continents were once all together. because there were fossils such as glossopteris and marsupials were found in the continents that indicate that the continents were. Wegener's Continental Drift Hypothesis. Figure 1. Alfred Wegener suggested that continental drift occurred as continents cut through the ocean floor, in the same way as this icebreaker plows through sea ice. Wegener put his idea and his evidence together in his book The Origin of Continents and Oceans, first published in 1915

The theory of plate tectonics explains many earth features, like ocean floor trenches and sediment-free mid-ocean ridges made of hardened magma. The popular theory holds that continents drift slowly across earth's surface atop deeply buried molten rock, and that plate movements creep along at leisurely paces. But new research by Yale University geologists calls that into question Question and answer. Which of the following was not a geological clue used to support the theory of continental drift? Samples of ocean water tested off the coast of South America contained the same salt content as oceans near Africa. [ -was not a geological clue used to support the theory of continental drift. However, there were several people who rejected the theory of Wegener because of lack of mechanism. Here are other interesting facts about continental drift below: Facts about Continental Drift 1: how the continents move. How the continents move is explained by the theory of plate tectonics using the continental drift idea (C) Wegener's theory of continental drift was an important step towards discovering plate tectonics, but it misunderstood the exact nature of the crust's movement. Clue 27(C)[!ines 48-49] his theory of continental drift,* the primary forerunner of plate tectonics [lines 55-58] Critics emphasized the failure of Wegener's theory to. Hypothesis --> Theory The difference between continental drift and plate tectonics is that the theory of continental drift states that the world was made up of a single continent.The theory of plate-tectonics, on the other hand, states that earth's surface is broken into numbers of shifting plates or slabs

Chapter 12, Section 1: Continental Drift - ProProfs Qui

In 1965, a Canadian geophysicist, J. Tuzo Wilson, combined the continental drift and seafloor spreading hypotheses to propose the theory of plate tectonics. Tuzo said that Earth's crust, or lithosphere, was divided into large, rigid pieces called plates. These plates float atop an underlying rock layer called the asthenosphere What Five Factors Did Wegener Use to Support His Theory? In proposing the theory of continental drift, Alfred Wegener relied on evidence from the shape of the continents, the distribution of plants and animals, similarities between landscapes, contiguous veins of ore that ran between continents, and the distribution of glacial deposits What two theories were combined to make the modern theory of plate tectonics? Continental drift theory and the seafloor spreading theory. 2. Why is plate tectonics now considered to be the dominant theory in Earth science Because it explains the nature of different natural disasters that happen such as earthquakes, volcanoes, and mountain.

Theory of Continental Drift Physical Geograph

Alfred Wegener's contemporaries rejected his theory of continental drift because it challenged many established scientific theories at the time, and he lacked a compelling explanation for the cause of continental drift. Wegener believed that continental drift was the result of centrifugal force and tidal attraction, but the scientific community. Scientists have long noticed the similarity between the two coastlines, but it was not until the 20th century that evidence could support a theory that the continents were once connected. In 1912 a German meteorologist named Alfred Wegener introduced the first detailed and comprehensive theory of continental drift The continental drift theory. Explain how the following pieces of evidence supported the continental drift theory. a) matching continental margins b) similar animal fossils in South America and Africa c) similar rock types and structures in North America and . Science. 2 In geologic terms, a plate is a large, rigid slab of solid rock. The word tectonics comes from the Greek root to build. Putting these two words together, we get the term plate tectonics, which refers to how the Earth's surface is built of plates. The theory of plate tectonics states that the Earth's outermost layer is fragmented into a dozen or more large and small plates that are moving. Continental drift met with a reception even cooler than usual, perhaps because its author was not a member of the geologists' circles. Although there were solid bits of evidence to support the theory, it was proved mathematically that the earth's crust is too strong to allow any lateral movement of the continents

What are the four pieces of evidence for continental drift

Based on the fit of the coastlines, fossil evidence, rock types, and mountain ranges found on separate continents, Alfred Wegener developed a new theory he called 'continental drift' The theory of continental drift But geologists soundly denounced Wegener's theory of continental drift after he published the details in a 1915 book called The Origin of Continents and Oceans. Part of the opposition was because Wegener didn't have a good model to explain how the continents moved apart

to support his theory. EXPLORE Working in small groups, students will piece together the supercontinent Pangea based on fossil and rock evidence found on present day continents. • Introduce the Pangea Map Symbols. Identify the symbols and discuss that these animals and plants once lived on Earth. •Give each group the landmass pieces and. Alfred Wegener. Wegener began by demolishing the theory that large land bridges had once connected the continents and had since sunk into the sea as part of a general cooling and contraction of the Earth. He pointed out that the continents are made of a different, less dense rock (granite) than the volcanic basalt that makes up the deep-sea. Plate tectonics is the scientific theory explaining the movement of the earth's crust. It is widely accepted by scientists today. Recall that both continental landmasses and the ocean floor are part of the earth's crust, and that the crust is broken into individual pieces called tectonic plates (Fig. 7.14) The Continental Drift Idea. Figure 1. The continents fit together like pieces of a puzzle. This is how they looked 250 million years ago. 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. That's the true size and shape of a continent Continental drift is the hypothesis that states the continents were once formed in a single landmass and then drifted apart to there present locations. Some pieces of evidence Wegener used to support his hypothesis are 1) through his observations, the continents seem to fit together
