Alfred Wegener proposed that the continents were once united into a single supercontinent named Pangaea, meaning all earth in ancient Greek. However, he supported his theory by explaining the earth's geologic history. This apparent fit is due to the fact the continents were once connected and have since moved apart in what has been called continental drift . Mesosaurus are fossils originating from aquatic freshwater reptiles. (No. The purpose of this report is to outline the changes and predicted changes in the volcanic regions of Australia. 4.

Sea floor spreading indicates that since the continents presently move apart, previous continental drift was possible and probable as well. 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. Wegener used fossil evidence to support his continental drift hypothesis. Over time the continents change position relative to one another as they move. Darwins finches from the Galapagos Islands. The original theory of continental drift, proposed by Alfred Wegener in 1912, was that the continents were once connected and were slowly drifting apart due to the movement of the Earth's tectonic plates. What evidence supports the theory of continental drift? Corrections? What evidence supports that the glaciers on the southern continents were once part of a single massive ice sheet? One of the strongest pieces of evidence is Continental break up/fit, this is the idea that the continents were once joined together. He died of an alleged heart attacked when on an expedition to Greenland. Late in the Triassic Period (which lasted from approximately 251 million to 199.6 million years ago), Pangea fragmented, and the parts began to move away from one another. Glossopteris was Fossil from fern. Noting the apparent fit of the bulge of eastern South America into the bight of Africa, the German naturalist Alexander von Humboldt theorized about 1800 that the lands bordering the Atlantic Ocean had once been joined. Which means Antarctica must have had a much warmer climate at one point, supporting Wegners theory of Continental drift. However, the crust is never destroyed when plates move past one another horizontally at transform boundaries. Fossils tell us when and where plants and animals once existed. There are two varieties of tectonic plates: Oceanic plates and Continental plates. Well, this claim was made in the 90s by Alfred Wegener, a German polar researcher, meteorologist and geophysicist who died in 1930. The poster child of scientific theory. A graphic of Gondwana.

The main piece of evidence supporting continental drift was the fit of the continents along their edges. One indication of this possibility is the appearance of the western African and eastern South American coasts, which look like two interlocking jigsaw puzzle pieces. Through the theory of continental drift, humans have been able to figure out how the earths crust moves and the causes of volcanoes, earthquakes, oceanic trenches, formation of mountain ranges and other geological occurrences. To support his theory Wegener pointed to matching rock formations and similar fossils in Brazil and West Africa. The shape of continental coastlines visibly matched up like pieces of the puzzle. At that time, the slabs of rock that carried these present-day continents crawled apart from each other at a rate of a millimeter a year.

The curves for Europe and North America, for example, are reconciled by the assumption that the latter has drifted about 30 westward relative to Europe since the Triassic Period. This is called Ridge Push. Grooves and rock deposits left by ancient glaciers are found today on different continents very close to the equator. This perfect aligning of mountain ranges indicated that the continents were once together.

Fossils of the Mesosaurus, an ancient freshwater reptile found in the southern parts of South America and Africa, also indicate that the two continents could have once been one solid continent that drifted apart, since the reptile could not have swum across the ocean. It is), Is Galvanized Steel Magnetic? Over the course of millions of year ago, this gradual movement caused the once combined supercontinent to separate into 7 continents you witness in the present day. Temperature and pressure both increase with depth. One of the reasons that dark matter has arisen as a theory is the fact that when we observe certain galaxies, they have much more kinetic energy then the masses in them would suggest, therefore, a separate force must be at play.

For example fossils of Mesosaurus a freshwater reptile have been found both in Brazil and western Africa. During the early 1960s, the American geophysicist Harry H. Hess proposed that new oceanic crust is continually generated by igneous activity at the crests of oceanic ridgessubmarine mountains that follow a sinuous course of about 65,000 km (40,000 miles) along the bottom of the major ocean basins. Gondwanaland contained all the masses in the southern hemisphere such as Africa, Antarctica, South America and Australia. Wegener supported his theory by demonstrating the biological and geological similarities between continents. As the plates move away from the flanks of the ridges, they carry the continents with them. Some 50 years later, Antonio Snider-Pellegrini, a French scientist, argued that the presence of identical fossil plants in both North American and European coal deposits could be explained if the two continents had formerly been connected, a relationship otherwise difficult to account for. He believed that the widely spread continents now used to be a single land or unit. . 2. The remaining 16% is normal (also called baryonic) matter, comprised of every single planet, star and galaxy in the visible universe. Wegener also provided evidence of continental drift by looking at the physical shape of continental coastlines. Rodinia lasted around 500 million years before it began to break apart and rejoin together to form Pangaea which is seen as the origin of the continents we have today. They based their idea of continental drift on several lines of evidence: fit of the continents, paleoclimate indicators, truncated geologic features, and fossils. Answer 5: Fossils are formed when living organisms (plants or animals) die and become buried in dirt, sand or mud. As magma rises it forces the crust to rise at the ridge. .

The Theory of Continental Drift was proposed by Alfred Wegener in 1912. Theory of Plate Tectonics was established by Alfred Wegener. Despite Wegeners effort to try to prove his theory of continental drift, it was never accepted. Wegner also noticed that rocks and mountain ranges across continents looked similar and were similar ages, the belt of ancient rocks of 2,000 million years ago from the Brazilian coast matches with those from western Africa he also noticed that there were similar geological sequences in eastern Canada and Scotland. If these continents were once united around the south polar region, this glaciation would become explicable as a unified sequence of events in time and space. Other examples of Fold Mountains are: The Andes, The Alps and The Rockies. What are the effects of light pollution on animals?

In this essay I will describe more in-depth about the Earths dynamic structure and how plate tectonics affected biotas. The present continents appear to fit together as pieces of a larger landmass. The plates continue to move apart at the speed that our fingernails grow. Molten rock material from Earths mantle rises upward to the crests, cools, and is later pushed aside by new intrusions. Fossils and Mountain ranges were his evidences. Government programs to settle the land Which is an example of geological fit evidence? The idea of a large-scale displacement of continents has a long history. Which two pieces of fossil evidence supports the idea of continental drift? Women authors in the 19th and early 20th centuries did lots of critical groundwork in revising Darwins theories to uncover and challenge the stereotypes that subordinated women, which gained validation under the EduBirdie considers academic integrity to be the essential part of the learning process and does not support any violation of the academic standards.

While making this claim, he had a collection of evidence to support it. Many people didn't believe him at first. What are the 5 evidences of continental drift? Fossils of creatures and plants discovered on different continents helped to him push his case that the continents were once locked together before breaking up and drifting away. Oceanic ridges occur along some of the plate margins. Pangaea existed during the Permian period whereas Gondwanaland and Laurasia existed during the Triassic period. Lystrosaurus is Fossil from land reptiles. Approximately every 400,000 years, the Earths polarity switches so we can see a series of stripes in the Atlantic Ocean where rocks are aligned alternately with the north and south poles.

The Mesosaurs would not have been able to swim across the ocean due to the fact they are freshwater creatures (and the vast distance between continents), so the mesosaurs at some point must have been able to walk across the continents. Fossil records are strong evidence that the continents do drift. Continental plates are 30km-70km thick whereas the thinner oceanic plates are only 5km-10km thick. We can also see that the basaltic rock gets older the further we travel from the mid Atlantic ridge, showing that new basaltic rock is made as the magma rises from the diverging plates. His ideas attracted much attention in the 1920s and generated much controversy. Privacy Policy So, the fact that these organisms could not swim through the vast water bodies helps to substantiate the fact that the continents were once together to allow distribution of these organisms in various continents where their fossils were found on.
