Describe the Evidence Wegener Used to Reconstruct Pangaea

With tongue-shaped leaves and seeds too large to be carried by the wind this plant was known to be widely dispersed thoughtout Africa Australia India and South America. Up to 24 cash back Key to Wegeners Puzzling Evidence Fossils.

Solved Pangea Reconstruction Describe The Process You Chegg Com

Evidence from fossilized organisms and mountain chains can be used to reconstruct the positions of todays continents and landmasses to form the supercontinent Pangea.

. The misconception that Alfred Wegener used the modern-day coastlines for his reconstruction of Pangea has been propagated from his day to the present. The Pangaea is known as supercontinent. Seafloor spreading occurs at divergent plate boundaries.

Evidence for Continental Drift Pangaea Evidence From Land FeaturesAs shown in Figure 12 mountains and other features on the continents provided evi- dence for continental drift. Fossils and geologic evidence show that most of the continents used to have startlingly different climates than they do today. For example fossils of warm-weather plants were found on the island of Spitsbergen in the Arctic Ocean.

To explain this Wegener hypothesized that Spitsbergen drifted from tropical regions to the arctic. Up to 24 cash back Climate CluesWegener used continental drift to explain evidence of changing climates. For example fossils of warm-weather plants were found on the island of Spitsbergen in the Arctic Ocean.

The theory encompasses the concepts of continental drift developed by Alfred Wegener and seafloor spreading. Plate tectonics model describes the large scale motions of Earth s lithosphere. Wegener thought continental drift was the key to these climatic puzzles so he and Vladimir Koppen plotted ancient deserts jungles and ice sheets on paleogeographic maps based on Wegeners theory.

Listexplain the 4 lines of evidence Alfred Wegener used to support his continental drift hypothesis. Wegener also used continental drift to explain evidence. SOLUTION- Question1 Alfred Wegener described the movement of continent to their present position through some evidences.

One is quite simple ie. The glacial deposits 3. Some of the evidence he collected included the following.

The puzzle-like fit of the continents identical fossils found on continents. He was German scientist. Describe the evidence Wegener used to reconstruct Pangaea-The European Flora -Glossopteris Plant-Cynognathus Reptile-Lystrosauthus Reptile.

Alfred Wegener brought together several lines of evidence to support his theory of continental drift. The continents look like they could fit together much like a puzzle pieces that have been drifted apart. The tectonic fit 5.

The lands as we knew them had been arranged by continental drift a process by which all the continents had begun their existence fused into one gigantic. Then he noticed that when you put the continental puzzle pieces back together. What pieces of evidence did Wegener use to reconstruct Pangaea.

Glossopteris Wegener also cited the distribution of the fossil seed fern Glossopterisas evidence for Pangaeas existence see Figure 24. 1the continents seemed to fit 2matching geologic units rock types structure 3fossil evidence mesosour a freshwater reptile. Alfred Wegener collected diverse pieces of evidence to support his theory including geological fit and fossil evidence.

By about 300 million years ago a unique community of plants had evolved known as the European flora. The fossil evidence 2. To explain this Wegener hypothesized that Spitsbergen drifted from tropical regions to the arctic.

German meteorologist Alfred Wegener first presented the concept of Pangea meaning all lands along with the first comprehensive theory of continental drift the idea that Earths continents slowly move relative to one another at a conference in 1912 and later in his book The Origin of Continents and Oceans 1915. He believed that millions of years ago the continents were joined into a single land mass. For example when Wegener piece d together maps of Africa and South America he noticed that mountain ranges on both continents line up.

A letter written by Wegener to his wife in 1911 demonstrates unequivocally that even before he first began to formulate the hypothesis of continental drift Wegener did not consider. Wegener also used continental drift to explain evidence. Climate CluesWegener used continental drift to explain evidence of changing climates.

Glossopteris ferns had very heavy seeds that could not move by wind or drift on ocean currents. The researchers in this study used biological and physical data from the Moradi Formation a region of layered paleosols fossil soils in northern Niger to reconstruct the ecosystem and climate. Up to 24 cash back In the early 1900s Alfred Wegener collected a lot of evidence to support his theory about the supercontinent Pangaea.

Given the locations of fossils glacial deposits and. Most geologists accept these tests as verification of plate tectonics. Fossils glacial deposits shapes of the continents and mountain ranges in their explanations.

Jigsaw fit- If we notice we see that View the full answer. He concluded with a sweeping observation. The jigsaw fit 4.

Describe The process of ocean floor spreading and how scientist prove it. Plate tectonics has been rigorously tested from numerous sub disciplines in geology. The existence of the supercontinent Pangaea was first evidenced by the fit of continents namely Africa and South America which led to the hypothesis of continental drift Alfred Wegeners.

Evidence to Prove That Pangaea had Existed Evidence of Continental Drift. The true polar wander component is identical for all samples and can be removed leaving geologists with the portion of this motion that shows continental drift and can be used to help reconstruct earlier continental positions. The continuity of mountain chains provides further evidence for Pangaea.

The continents are surrounded by the continental shelfstippled pattern which extends beyond the continent until there is a large change in slope. Fossils have been found on all the southern continents Australia Antarctica India. Evidences are - 1.

Which of the following did Wegener conclude about the continents. Wegener himself did not collect the fossils but he called attention to the idea of using these scientific doc uments stating there. It is important to know that the following specific fossil evidence was not brought up by Wegener to support his theory.

Mountain chains on cut-out pieces of the continent the student should be able to reconstruct a model of the supercontinent Pangaea by placing five of the seven.
