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 are the 6 pieces of evidence for the theory of continental drift?
What are six pieces of evidence for the continental drift theory?
Reptile Fossils
– dinosaurs couldn’t have swam across a vast ocean. Plant Fossils- all these regions were once connected and had similar climates. Tropical plants found in Arctic- tropical plants can’t grow in cold climates.
What are 3 lines of evidence used to support the drifting of the continent?
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
.
Which of the following are pieces of evidence that Wegener used to support his idea of continental drift?
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.
What was Alfred Wegener’s theory of continental drift?
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.
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 does Pangaea mean in Greek?
Pangea was surrounded by a global ocean called Panthalassa, and it was fully assembled by the Early Permian Epoch (some 299 million to 273 million years ago). … Its name is derived from the Greek pangaia, meaning
“all the Earth
.”
What are the 4 pieces of evidence 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 is the evidence for Pangea?
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. Fossil evidence for Pangaea includes
the presence of similar and identical species on continents that are now great distances apart
.
What is believed to cause the plates to move?
The heat from radioactive processes within the planet’s interior
causes the plates to move, sometimes toward and sometimes away from each other. This movement is called plate motion, or tectonic shift.
What are two pieces of evidence for seafloor spreading?
Several types of evidence from the oceans supported Hess’s theory of sea-floor spreading-
evidence from molten material, magnetic stripes, and drilling samples
. This evidence also led sci- entists to look again at Wegener’s theory of continental drift.
What was the response to Wegener’s hypothesis?
“That was always his response:
Just assert it again, even more strongly
.” By the time Wegener published the final version of his theory, in 1929, he was certain it would sweep other theories aside and pull together all the accumulating evidence into a unifying vision of the earth’s history.
What is continental drift theory explain?
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.
Which piece of evidence did Alfred Wegener’s original theory of continental drift have access to?
Wegener’s first piece of evidence was that
the coastlines of some continents fit together like pieces of a jigsaw puzzle
. People noticed the similarities in the coastlines of South America and Africa on the first world maps, and some suggested the continents had been ripped apart [3].
What are the 3 theories of plate tectonics?
The three types of plate boundaries are
divergent, convergent, and transform
. They are described in the following three concepts. Most geological activity takes place at plate boundaries.
What is the best piece of evidence for plate tectonics?
Evidence from
fossils, glaciers, and complementary coastlines
helps reveal how the plates once fit together. Fossils tell us when and where plants and animals once existed. Some life “rode” on diverging plates, became isolated, and evolved into new species.
