What Supports Wegener’s Theory Of Continental Drift?

Wegener supported his theory by demonstrating the biological and geological similarities between continents. South America and Africa contain fossils of animals found only on those two continents with corresponding geographic ranges.

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.

What evidence best supports the theory of continental drift?

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 supports Wegener’s theory of plate tectonics?

Theory of Plate Tectonics was established by Alfred Wegener. Fossils and Mountain ranges were his evidences. Alfred Wegener created the idea of continental drift and wrote ‘The Origin of Continents and Oceans’ to support his idea. … Fossils are the stongest evidences of plate tectonics.

Which land feature supports the theory of continental drift?

Canyon supports the theory of continental drift.

How do the continental coastlines support the theory of continental drift?

Continental Coastlines appearing to fit together Fossil Distrubution … By having matching patterns it indicates that the two continents and their rocks were at one time one continent. How does coal distribution support the Theory of Continental Drift? Coal normally forms in warm wet climates.

What evidence did Wegener rely on in the formulation of his theory of continental drift What evidence did he lack?

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.

How did Alfred Wegener come up with the continental drift theory?

Fossils of similar organisms across widely disparate continents encouraged the revolutionary theory of continental drift. … He called this movement continental drift. Pangaea. Wegener was convinced that all of Earth’s continents were once part of an enormous single landmass called Pangaea.

What are 6 pieces of evidence that support 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.

What are 5 pieces of evidence that support continental drift?

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 were the facts that support the theory of Wegener?

Evidence for continental drift

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. He also matched up rocks on either side of the Atlantic Ocean like puzzle pieces.

Which land feature supports the theory of continental drift quizlet?

the land features that provided evidence for Wegener’s hypothesis is that mountain ranges in South America and Africa line -up coal fields in North America and Europe are the same and the east coast of South America fits into the west coast of Africa or vice versa.

Which statement describes one of Wegener’s ideas that contributed to theory of continental drift?

Which statement describes one of Wegener’s ideas that contributed to the theory of continental drift? The continents drifted apart due to repeated meteor impacts.

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.

How does coal deposits support continental drift?

The coal deposits only mean that Antarctica might have been positioned in a part of the Earth where it once supported large quantities of life. … This leads to the idea that Antarctica once experienced a tropical climate thus it might have been closer to the equator.

How do convection currents cause continental drift?

Geologists have hypothesized that the movement of tectonic plates is related to convection currents in the earth’s mantle. … Tremendous heat and pressure within the earth cause the hot magma to flow in convection currents. These currents cause the movement of the tectonic plates that make up the earth’s crust.

What drives continental drift?

The causes of continental drift are perfectly explained by the plate tectonic theory. The earth’s outer shell is composed of plates that move a little bit every year. Heat coming from the interior of the earth triggers this movement to occur through convection currents inside the mantle.

Why did scientists reject Wegener’s idea of continental drift?

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.

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 evidence supports the idea that all the continents were once joined together?

In the early part of the 20th century scientists began to put together evidence that the continents could move around on Earth’s surface. 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 did Alfred Wegener discover?

Lived 1880 – 1930.

Alfred Wegener proposed the theory of continental drift – the idea that Earth’s continents move. Despite publishing a large body of compelling fossil and rock evidence for his theory between 1912 and 1929 it was rejected by most other scientists.

When did Alfred Wegener propose his theory?

1912

Wegener first presented his theory in lectures in 1912 and published it in full in 1915 in his most important work Die Entstehung der Kontinente und Ozeane (The Origin of Continents and Oceans).

What other contributions did Alfred Wegener make towards science?

Wegener was a German meteorologist geophysicist and polar researcher. In 1915 he published ‘The Origin of Continents and Oceans’ which outlined his theory of Continental Drift. Wegener was a member of four expeditions to Greenland.

How did Dr Alfred Wegener use both fossils and present day plants and animals to support continental drift theory?

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.
