The puzzle-like fit of the continents identical fossils found on continents.
. The latitudes implied by the magnetization of late Paleozoic age rocks from the various continents are consistent with the latitude that Wegener place them at in. 1the continents seemed to fit. It is important to know that the following specific fossil evidence was not brought up by Wegener to support his theory.
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. For example when Wegener piece d together maps of Africa and South America he noticed that mountain ranges on both continents line up. Lack of evidence for it.
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. Plate tectonics model describes the large scale motions of Earth s lithosphere. The tectonic fit 5.
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. 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.
SOLUTION- Question1 Alfred Wegener described the movement of continent to their present position through some evidences. Glossopteris Wegener also cited the distribution of the fossil seed fern Glossopterisas evidence for Pangaeas existence see Figure 24. Wegener also used continental drift to explain evidence.
Plate tectonics has been rigorously tested from numerous sub disciplines in geology. The misconception that Alfred Wegener used the modern-day coastlines for his reconstruction of Pangea has been propagated from his day to the present. Fossils and geologic evidence show that most of the continents used to have startlingly different climates than they do today.
The name Pangaea is derived from Ancient Greek pan πᾶν all entire whole and Gaia or Gaea Γαῖα Mother Earth land. He was German scientist. Wegener himself did not collect the fossils but he called attention to the idea of using these scientific doc uments stating there.
Fossils glacial deposits shapes of the continents and mountain ranges in their explanations. Up to 24 cash back Key to Wegeners Puzzling Evidence Fossils. 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.
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. 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. About 100 years ago a German scientist named Alfred Wegener made the observation that continents fit together.
The concept that the continents once formed a contiguous land mass was hypothesised with corroborating evidence by Alfred Wegener the originator of the scientific theory of. Listexplain the 4 lines of evidence Alfred Wegener used to support his continental drift hypothesis. 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.
The jigsaw fit 4. It split apart millions of years ago and the continents moved to their present position. Describe The process of ocean floor spreading and how scientist prove it.
Evidences are - 1. The continents are surrounded by the continental shelfstippled pattern which extends beyond the continent until there is a large change in slope. Then he noticed that when you put the continental puzzle pieces back together.
Given the locations of fossils glacial deposits and. The Pangaea is known as supercontinent. World map of Pangaea created by Alfred Wegener to illustrate his concept.
Seafloor spreading occurs at divergent plate boundaries. 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. Describe the evidence Wegener used to reconstruct Pangaea-The European Flora -Glossopteris Plant-Cynognathus Reptile-Lystrosauthus Reptile.
Most geologists accept these tests as verification of plate tectonics. The fossil evidence 2. For example fossils of warm-weather plants were found on the island of Spitsbergen in the Arctic Ocean.
The continents look like they could fit together much like a puzzle pieces that have been drifted apart. The theory encompasses the concepts of continental drift developed by Alfred Wegener and seafloor spreading. Which of the following did Wegener conclude about the continents.
When the theory was first described there was no known mechanism that could explain how the earth could be old enough for the theory to be true. This led him to suggest a new idea that the continents were once part of a single piece of land called Pangea. He believed that millions of years ago the continents were joined into a single land mass.
Some of the evidence he collected included the following. Up to 24 cash back In the early 1900s Alfred Wegener collected a lot of evidence to support his theory about the supercontinent Pangaea. He concluded with a sweeping observation.
There was no mechanism for causing. 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 fitting the continents at. Alfred Wegener brought together several lines of evidence to support his theory of continental drift.
To explain this Wegener hypothesized that Spitsbergen drifted from tropical regions to the arctic. The glacial deposits 3. Climate CluesWegener used continental drift to explain evidence of changing climates.
