What are 4 pieces of evidence that support the theory 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 are the evidence of continental drift?
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 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.
Which evidence best supports 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 are 3 pieces of evidence for Pangea?
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 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.
Why was the continental drift theory rejected?
This idea was quickly rejected by the scientific community primarily because
the actual forces generated by the rotation of the earth were calculated to be insufficient to move continents
.
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.
Which of these did not provide evidence for continental drift?
Which of these did NOT provide evidence for continental drift?
oceanic plate theory
.
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
.
Which of the following answers is evidence for continental drift except?
Wegener used all the following to provide evidence for continental drift except :
age of selected continental rocks
.
What can you say about the continental drift and what does this mean about our origins?
Continental drift
describes one of the earliest ways geologists thought continents moved over time
. This map displays an early “supercontinent,” Gondwana, which eventually moved to form the continents we know today. … The theory of continental drift is most associated with the scientist Alfred Wegener.
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.
What is the difference between continental drift and plate tectonics?
The theory of continental drift suggests that
all the land masses on earth were once part of one supercontinent
. Plate tectonics is the ability to measure the movement of land masses.
Is continental drift the same as plate tectonics?
Plate tectonics explains why Earth’s continents are moving; the theory of continental drift did not provide an explanation. Therefore, the theory of plate tectonics is
more complete
.
