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 4 pieces of evidence for 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 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. .
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 the evidence for continental drift and plate tectonics?
Modern continents hold clues to their distant past. Evidence from fossils, glaciers, and complementary coastlines helps reveal how the plates once fit together.
What is continental drift theory explain?
Continental drift describes one of the earliest ways geologists thought continents moved over time. … 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.

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? Check the answer of
Who proposed the concept of continental drift quizlet?
In 1915, the German geologist and meteorologist Alfred Wegener first proposed the theory of continental drift, which states that parts of the Earth’s crust slowly drift atop a liquid core.
Did dinosaurs live on Pangea?
Dinosaurs lived on all of the continents. At the beginning of the age of dinosaurs (during the Triassic Period, about 230 million years ago), the continents were arranged together as a single supercontinent called Pangea. During the 165 million years of dinosaur existence this supercontinent slowly broke apart. Read:
What evidence supports the Pangaea theory?
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.
Why was Pangea not accepted?
Despite having this geological and paleontological evidence, Wegener’s theory of continental drift was not accepted by the scientific community, because his explanation of the driving forces behind continental movement (which he said stemmed from the pulling force that created Earth’s equatorial bulge or the …
Why was the continental drift theory 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.
What are the 4 types of plate tectonics?
There are four types of boundaries between tectonic plates that are defined by the movement of the plates: divergent and convergent boundaries, transform fault boundaries, and plate boundary zones.
Why is the continental drift theory important?
continental drift, large-scale horizontal movements of continents relative to one another and to the ocean basins during one or more episodes of geologic time. … This concept was an important precursor to the development of the theory of plate tectonics, which incorporates it.
What is the nickname for continental drift?
What is the nickname for continental drift? Pangea’s existence was first proposed in 1912 by German meteorologist Alfred Wegener as a part of his theory of continental drift. Its name is derived from the Greek pangaia, meaning “all the Earth.”
What is continental drift theory class 11?
The theory of continental drift points out that the Earth’s continents are constantly drifting away from each other. According to this theory: all the continents were one single continental mass (called a Super Continent) – Pangaea. The earth’s crust is m
