In what continents do Glossopteris fossils were found?

In what continents do Glossopteris fossils were found?

The Glossopteris fossil is found in Australia, Antarctica, India, South Africa, and South America—all the southern continents.

On which continent were fossils of Glossopteris and Lystrosaurus?

Fossils of Lystrosaurus are only found in Antarctica, India and South Africa. Glossopteris was a woody, seed-bearing shrub or tree, named after the Greek descripton of ‘tongue’ – a description of the shape of the leaves.

How did the discovery of Glossopteris support Wegener’s continental drift theory?

How did the discovery of Glossopteris support Wegener’s continental drift hypothesis? It shows its was spread around in all different continents whose climates are all different now. They found more rock, fossils and climate evidence because of today’s technology.

What does the Glossopteris fossils tell us about the positions of continents?

Answer: The Glossopteris fossils are the most abundant resources which tells more about the super continent. Explanation: It is believed that this woody plants fossils could be found in every continent as the research records claims that once they used to live on the entire Pangea before continental drift.

What do the Glossopteris fossils tell us about?

Glossopteris fossils tell us that the continents especially Southern Africa, Australia, India and Antarctica which are now separated by wide oceans were once connected because the large seeds of this plant could not possibly travel a long journey by the wind or survive a rough ride through ocean waves.

What does the presence of Mesosaurus fossil?

The Mesosaurus fossils tell us that South America, Africa and Antarctica were once connected because it is impossible for these reptiles to swim over the vast oceans and move from one continent to another.

Does the case by itself prove the theory?

Does the case by itself prove the theory? No, because it was only one reptile.

How can fossils be used as evidence 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.

Why is Continental Drift accepted now?

Pangaea existed about 240 million years ago. By about 200 million years ago, this supercontinent began breaking up. Over millions of years, Pangaea separated into pieces that moved away from one another. These pieces slowly assumed their positions as the continent we recognize today.

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 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 the theory of seafloor spreading?

Seafloor spreading, theory that oceanic crust forms along submarine mountain zones, known collectively as the mid-ocean ridge system, and spreads out laterally away from them. …

What is the continental drift theory What are the evidence supporting the same Upsc?

According to the theory, all the continents formed a single continental mass- Pangea and mega ocean- Panthalassa surrounded it. Around 200 million years ago Pangaea started splitting and broke down into two large continental masses as Laurasia and Gondwanaland forming the northern and southern components respectively.

Which two pieces of fossil evidence support the idea of 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 the similarities and differences of plate tectonics and continental drift?

The difference between continental drift and plate tectonics is that the theory of continental drift states that the world was made up of a single continent. The theory of plate-tectonics, on the other hand, states that earth’s surface is broken into numbers of shifting plates or slabs.

How did Pangea split?

During the Triassic Period, the immense Pangea landmass began breaking apart as a result of continental rifting. A rift zone running the width of the supercontinent began to open up an ocean that would eventually separate the landmass into two enormous continents.

What is the relationship 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.

What are 3 possible causes of plate tectonics?

In this lesson, we explore the causes of plate movement, including thermal convection, ridge push and slab pull.

What is the major difference between continental drift and plate tectonics quizlet?

Terms in this set (11) What are the differences between Continental Drift and Plate Tectonics? Continental drift believes that the continents moved because the magnetism of the sea floor. Plate tectonics believes that the lithosphere & the asthenosphere of the continents caused them to move.

What is the major difference in the role of the ocean floor between the continental drift hypothesis to the theory of plate tectonics?

What is the major difference in the role of the ocean floor between the continental hypothesis and the theory of plate tectonics? In the theory of plate tectonics, the ocean floor produces earthquakes, volcanoes, mountains, etc. But, in the continental hypothesis, the ocean floor causes the movements of the continents.
