What Supports Wegener’s Hypothesis Of Continental Drift?
Wegener used fossil evidence to support his continental drift hypothesis. The fossils of these organisms are found on lands that are now far apart. … Wegener suggested that these creatures were alive in warm climate zones and that the fossils and coal later had drifted to new locations on the continents.Aug 11 2020
What facts support Wegener’s theory of continental drift?
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.
What are 5 pieces of evidence that support 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.
What best supports the theory of continental drift hypothesis?
Fossil Evidence
One type of evidence that strongly supported the Theory of Continental Drift is the fossil record. 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.
What are the 4 evidences of continental drift?
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.
Which land feature supports the theory of continental drift?
Canyon supports the theory of continental drift.
Which statement does not support Wegener’s theory of continental drift?
Wegener’s continental drift hypothesis was not supported by evidence. Wegener’s continental drift hypothesis did not give a plausible explanation for how continents move. Wegener’s continental drift hypothesis did not state that the continents were arranged into a supercontinent many millions of years ago.
What was the response to Wegener’s hypothesis?
The main problem with Wegener’s hypothesis of Continental Drift was the lack of a mechanism. He did not have an explanation for how the continents moved. His attempt to explain it using tides only made things worse. But both Galileo and Darwin had serious flaws in their theories when they were first presented.
What evidence supports the theory of continental drift quizlet?
The Theory of Continental Drift was proposed by Alfred Wegener in 1912. He used several pieces of evidence to support his theory including fossils rocks glacial markings coal deposits and the fact that the continents fit together like a jigsaw puzzle. .
Why was Wegener’s idea of continental drift rejected?
The main reason that Wegener’s hypothesis was not accepted was because he suggested no mechanism for moving the continents. He thought the force of Earth’s spin was sufficient to cause continents to move but geologists knew that rocks are too strong for this to be true.
Who supported continental drift?
scientist Alfred Wegener
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.Jun 1 2015
What is Wegener’s theory of continental drift Class 7?
He proposed that millions of years ago all landmasses were joined together into a super continent called Pangaea. He suggested that the Pangaea broke and there was a horizontal displacement of the continents. This is called Wegener’s Theory of Continental Drift.
What evidence did Alfred Wegener provide to support his continental drift hypothesis check all that apply?
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.
What evidence supports the theory of continental drift check all that apply?
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.
What evidence supports the idea that all the continents were once joined together gizmo?
Scientists have found that rocks on the east coast of South America are the same as rocks found on the west coast of Africa. These rocks are different from rocks found in other places on Earth suggesting that the continents were once connected. Plant and animal fossils also reveal evidence.
Which statement would best support Wegener’s hypothesis?
The continents we see today are fragments of that supercontinent. To support his theory Wegener pointed to matching rock formations and similar fossils in Brazil and West Africa. In addition South America and Africa looked like they could fit together like puzzle pieces.
What evidence best supports the plate tectonic theory?
Which statement describes one of Wegener’s ideas that contributed to the theory of continental drift quizlet?
Which statement describes one of Wegener’s ideas that contributed to the theory of continental drift? The continents were once connected as one landmass. When were Earth’s landmasses first recognizable as the continents we know today?
Why was continental drift so controversial during Alfred Wegener’s time what explanation was necessary to support his hypothesis?
What explanation was necessary to support his hypothesis? Continental drift is not easily observable because tectonic plates move very slowly. When Wegener proposed the continental drift hypothesis he was unable to identify a force that could move continents.
What two pieces of evidence did Wegener discover that supported the idea of Pangaea quizlet?
what two pieces of evidence did wegener discover that supported the idea of Pangaea? 2. Mountain ranges and the location of ancient climatic zones. What does Pangaea mean in Greek?
Why was Wegener’s continental drift hypothesis rejected when it was proposed quizlet?
Why was Wegener’s hypothesis rejected? Because Wegener could not identify the cause of continental drift most geologists rejected his idea. Continental drift was what Wegener invented. Wegener’s hypothesis was rejected from geologists because he couldn’t identify the cause of continental drift.
Who is Wegener and what did he do?
What are the evidence in support of the continental drift theory Class 11 geography?
Evidence in Support of Continental Drift Theory: Matching of Continents: The shorelines of Africa and South America facing each other have a remarkable and unmistakable match. A computer simulations also matched these continents. The match was tried at 1 000 fathom line instead of present shoreline.
Which observations supported Alfred Wegener’s theory of continental drift during his lifetime choose more than one answer?
What evidence did Wegener gather and study to support his hypothesis? He studied land features. Wegener examined land features such as the margins of the continents mountain belts rock layers and mineral deposits and matched these features with similar features found on other continents.
What evidence supports the idea that all the continents were together?
Wegener then assembled an impressive amount of evidence to show that Earth’s continents were once connected in a single supercontinent. Wegener knew that fossil plants and animals such as mesosaurs a freshwater reptile found only South America and Africa during the Permian period could be found on many continents.
What evidence exists to support the existence of Pangea 3 points?
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. Together these discoveries supported the existence of Pangea.
What evidence exists to support the existence of Pangea quizlet?
Fossils of identical organisms were found on several continents indicating the continents were once joined. Late Paleozoic sedimentary rocks often contain extensive coal seams that were used to support the existence of Pangaea.
What helped scientists develop the theory of plate tectonics?
Evidence that led to the development of plate tectonic theory in the 1960s came primarily from new data from the sea floor including topography and the magnetism of rocks.
Which of the following observations about landforms best supports the theory of plate tectonics?
Which of the following observations about landforms best supports the theory of plate tectonics? Impact craters have been found both on dry land and on the ocean floor. As lava cools on Earth’s surface it forms a variety of igneous rocks. Volcanoes are distributed randomly on every continent.
How is plate tectonics supported by the apparent fit of the continental coastline?
This apparent fit is due to the fact the continents were once connected and have since moved apart in what has been called continental drift . However we now know that it is not just the continents that move so a more correct term is plate tectonics .
Which source of evidence did Wegener use to support his theory of continental drift fossils magnetic fields satellite mapping warm equatorial climates?
Wegener used fossil evidence to support his continental drift hypothesis. The fossils of these organisms are found on lands that are now far apart. Wegener suggested that when the organisms were alive the lands were joined and the organisms were living side-by-side.
Which indicates how evidence of climate change supports the theory of continental drift ??
The ‘same animal fossils’ found on different continents provide evidence climatic change on continent supporting the theory of ‘continental drift’. Explanation: The continental drift is actually a theory that has been made how the continents are shifted their position on the surface of the earth.
Which two pieces of fossil evidence supports the idea of continental drift quizlet?
How does each fossil support the hypothesis of continental drift? Each fossil supports this idea because they were found on different continents. What three key evidence supports continental drift? Fossil clues plants rock clues and climate clues were discovered on the different continents.
What was Wegener’s hypothesis of continental drift quizlet?
Wegeners hypothesis was that all the continents were once joined together in a single landmass and have since drifted apart. Wegener gathered evidence from different scientific fields to support his ideas about continental drift. He studied land features fossils and evidence of climate change.
