What two fossils support the theory of Pangaea?

Evidence. Two fossils in particular served as good evidence for the idea that the continents were once joined but have since separated: Glossopteris and Mesosaurus.

What fossil evidence supports the idea of Pangea?

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 two pieces of evidence that support Pangea?

The rock formations of eastern North America, Western Europe, and northwestern Africa were later found to have a common origin, and they overlapped in time with the presence of Gondwanaland. Together, these discoveries supported the existence of Pangea.

What were the two fossils Wegener found that helped support his theory?

Fossils also provided evidence to support Wegener’s theory. A fossil is any trace of an ancient organism preserved in rock. The fossils of the reptiles Mesosaurus and Lystrosaurus and a fernlike plant called Glossopteris have been found on widely separated landmasses.

What are 4 evidences that support the theory of Pangea?

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 Pangea theory?

Pangaea theory, according to National Geographic, suggested that the tectonic plates forming the planet’s outer crust slid over the inner layers until they merged as a landmass surrounded by a massive ocean called Panthalassa.

How were fossils used to prove continents?

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.

How do fossils support the theory of evolution?

Fossils of the simplest organisms are found in the oldest rocks, and fossils of more complex organisms in the newest rocks. This supports Darwin’s theory of evolution, which states that simple life forms gradually evolved into more complex ones. Evidence for early forms of life comes from fossils.

What are trace fossils 2 examples?

Ichnofossils, also known as trace fossils, are geological records of the activities and behaviors of past life. Some examples include rock evidence of nests, burrows, footprints, and scat.

Why did Wegener use fossils to support his 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.

What is Alfred Wegener theory?

The theory of continental drift is most associated with the scientist Alfred Wegener. 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.

How was Alfred Wegener connected to Pangaea?

In 1912 Alfred Wegener (1880-1930) noticed the same thing and proposed that the continents were once compressed into a single protocontinent which he called Pangaea (meaning “all lands”), and over time they have drifted apart into their current distribution.

What is the sea that divides the two major continents in Pangaea?

Atlantic Ocean

Today these two continents are separated by the Atlantic Ocean which is over 2000 miles wide! About 135 million years ago Laurasia was still moving, and as it moved it broke up into the continents of North America, Europe and Asia (Eurasian plate).

Who were the two scientist who proposed the theory of seafloor spreading in the early 1960’s?

The idea that the seafloor itself moves and also carries the continents with it as it spreads from a central rift axis was proposed by Harold Hammond Hess from Princeton University and Robert Dietz of the U.S. Naval Electronics Laboratory in San Diego in the 1960s. The phenomenon is known today as plate tectonics.

Who are the two scientists who proposed the theory of seafloor spreading Charles Darwin and James Hutton Harry Hess and Robert Dieter Arthur smite F Mathews?

Harry Hess and Robert Dietz. C. John Butler and Arthur Smite. D. F. Vine and D.

What two scientists proposed the theory of seafloor spreading in the early 1960s Quizizz?

DURING THE 1960’s Harry Hess and Robert Dietz suggested an explanation for the movement of the continents called Seafloor Spreading Theory.

What evidence supports the theory of ocean floor?

Harry Hess’s hypothesis about seafloor spreading had collected several pieces of evidence to support the theory. This evidence was from the investigations of the molten material, seafloor drilling, radiometric age dating and fossil ages, and the magnetic stripes.

What evidence helped give strong support for the hypothesis of seafloor spreading at mid-ocean ridges?

This hypothesis was supported by several lines of evidence: (1) at or near the crest of the ridge, the rocks are very young, and they become progressively older away from the ridge crest; (2) the youngest rocks at the ridge crest always have present-day (normal) polarity; and (3) stripes of rock parallel to the ridge …

What evidence first supported the theory of seafloor spreading Site 1 Brainly?

The magnetism of mid-ocean ridges helped scientists first identify the process of seafloor spreading in the early 20th century. … Oceanic crust slowly moves away from mid-ocean ridges and sites of seafloor spreading.

Which statement best supports the theory of continental drift?

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 evidence from fossils supported the hypothesis 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.

Which statement best supports the theory that all the continents?

Which statement best supports the theory that all the continents were once a single landmass? Rock and fossil correlation can be made where the continents appear to fit together. Which statement best supports the theory of continental drift? The present continents appear to fit together as pieces of a larger landmass.

What type of evidence support the theory of continental drift group of answer choices?

Alfred Wegener collected diverse pieces of evidence to support his theory, including geological “fit” and fossil evidence.

Which two pieces of fossil evidence support the idea of continental drift quizlet?

How does each fossil support the hypothesis of continental drift? Each fossil supports this idea because they were found on different continents. What three key evidence supports continental drift? Fossil clues, plants, rock clues and climate clues were discovered on the different continents.

What geologic evidence exists to support the theory that southern Africa South America Antarctica and India were once one landmass?

Fossils are found in Australia, South Africa,South America, India and Antarctica. When the continents of the southern hemisphere are re-assembled into the single land mass of Gondwanaland, the distribution of these four fossil types form linear and continuous patterns of distribution across continental boundaries.
