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 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 the evidences of 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 are the four pieces of evidence for continental drift quizlet?
List four pieces of evidence for Wegener’s hypothesis of continental drift?
Continents fit like a puzzle, climate clues, fossil clues, and rock layers or formations
. What was the name of the reptile that Wegners found in both South America and Africa?
What are the four pieces of evidence for Pangaea?
- Fossil Correlation. unique remains in distant places.
- Rock Correlation. identical rocks, mountains and structures.
- Apparent Fit. continents look like puzzle pieces and seem to fit together.
- Paleoclimate Data. coal found in cold regions, glacial evidence found in warm regions.
What are the 5 evidences of continental drift theory?
They based their idea of continental drift on several lines of evidence:
fit of the continents, paleoclimate indicators, truncated geologic features, and fossils
.
What observations led to the proposal of continental drift?
What observations led to the proposal of continental drift?
The matching coastlines of continents of opposite sides of the Atlantic Ocean suggest that the continents were once joined
.
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 evidence supports the theory of continental drift quizlet?
Fossils of same creature have been found on different continents that are separated today but were once joined
. For example. a 20 cm Mesosaurus reptile could not have swam 3000 miles across and ocean. It’s more likely the continents were together and over 40 million years it walked.
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 are the evidences of plate movements?
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 are the four types of plate boundaries?
- Convergent boundaries: where two plates are colliding. Subduction zones occur when one or both of the tectonic plates are composed of oceanic crust. …
- Divergent boundaries – where two plates are moving apart. …
- Transform boundaries – where plates slide passed each other.
Is the continental drift?
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 Alfred Wegener theory?
Alfred Wegener in Greenland. Plate tectonics is
the theory that Earth’s land masses are in constant motion
. The realization that Earth’s land masses move was first proposed by Alfred Wegener, which he called continental drift. … But the continents actually are shifting, very slowly, relative to one another.
What are evidence of seafloor spreading?
The study of the repeated reversal of the Earth’s magnetic poles over time
has provided convincing evidence of seafloor spreading. Objective: To explore how magnetic studies and age information provide evidence for seafloor spreading that explains why oceanic crust is younger than continental crust.
What is the second evidence of continental drift theory?
Alfred Wegener collected diverse pieces of evidence to support his theory, including geological “fit” and fossil evidence. … Another important piece of evidence in the Continental Drift theory is
the fossil relevance
. There are various examples of fossils found on separate continents and in no other regions.
