Rocks of Same Age Across the Oceans: The belt of ancient rocks of 2,000 million years from Brazil coast matches with those from western Africa. Wegener supported his theory by demonstrating the biological and geological similarities between continents. Particles of magnetized minerals released from their parent igneous rocks by weathering may later realign themselves with the existing magnetic field at the time these particles are incorporated into sedimentary deposits. Destruction happens when one plate moves below the other at convergent boundaries. Laurasia, makes up the northern continents of today. This drifting takes millions of years to complete this process.

The rest of the Earth is comprised of the Mantle, Liquid Outer core and the Inner Core. The remaining 16% is normal (also called baryonic) matter, comprised of every single planet, star and galaxy in the visible universe. Wegener found coal in Greenland and claimed that this supported his ideas about continental drift. What observations about landforms best supports the theory of plate tectonics? 2 What are the 6 pieces of evidence for the theory of continental drift?

The fossils of these organisms are found on lands that are now far apart. Continental drift has impacted the universe in many ways. Magnetic Reversals After molten lava emerges from a volcano, it solidifies to a rock. What pieces of evidence were used to support continental drift? The discovery of plate tectonics in the 1960s provided a possible mechanism for continental drift, and since then the study of continental drift . Evidence from fossils, glaciers, and complementary coastlines helps reveal how the plates once fit together. Scientists agree that continents rest on rocks called tectonic plates, which shift and move. The continents shapes fit well together and some continents have the same fossils. Mesosaurus - small fresh water reptile. However, further work showed that the polar wandering curves are different for the various continents. Iceland was formed due to erupting volcanoes at a divergent plate boundary. 6 How did Alfred Wegener come up with the idea of continental drift? What are the 5 evidences of continental drift? Continental drift is defined as the motion of the earth's continents over a defined period of time.

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. 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.Aug 11 2020, Theblogy.com B. What pieces of evidence were used to support plate tectonics? Which means Antarctica must have had a much warmer climate at one point, supporting Wegners theory of Continental drift. Paleoclimate Data. It is a fern that was discovered in Africa, South America, Antarctica, India, and Australia. Not all events are good ones, especially with the rough terrain that African had to endure, but also the good that came out of it from raw materials, but also involved exploitation. answer choices True A belt of ancient rocks along the Brazilian coast, for example, matches one in West Africa. It suggested that those land areas had in the past been connected. What was probably the first evidence that led some to suspect the continents were once connected? At convergent plates, oceanic and continental plates collide. 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. Rock Correlation. Over time, the organism decays and the area it occupied is replaced with inorganic rock. They based their idea of continental drift on several lines of evidence: fit of the continents, paleoclimate indicators, truncated geologic features, and fossils. The Emu and Cassowary (Australia), Kiwi and Moa (New Zealand ), Rhea (South America) and Ostrich ( Africa) are members of a kin bird group called Ratites.

As the crust rises, gravity forces it away from the margin, driving the crust. 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.

For example fossils of Mesosaurus a freshwater reptile have been found both in Brazil and western Africa. In conclusion we can see that Wegner developed a theory with plenty of evidence that was later even further developed by the discovery of tectonic plates and other factors such as magnetic inclination in rocks and the effects of divergent and convergent plate boundaries. The earths outer shell is composed of plates that move a little bit every year. To provide the best experiences, we use technologies like cookies to store and/or access device information.

Indications of widespread glaciation from 380 to 250 million years ago are evident in Antarctica, southern South America, southern Africa, India, and Australia. Wegener specifically used rock composition and mountain ranges to provide evidence of continental drift. 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. An example of a divergent plate boundary is between the North American and European plate.

South America and Africa contain fossils of animals found only on those two continents, with corresponding geographic ranges. (askinglot.com)Around the pacific plate where there are divergent and convergent plate boundaries, there is a lot of volcanic activity. On the other hand, tectonic movement destroys crust during interaction of the plates. This essay is available online and was probably used by another student. Biogeography. What is the first lines of evidence suggesting the existence of plate tectonics? The hypothesis addresses how the continents and oceans are distributed. As they are the same density, they break when they collide and are forced upwards instead. Not consenting or withdrawing consent, may adversely affect certain features and functions.

Gondwanaland contained all the masses in the southern hemisphere such as Africa, Antarctica, South America and Australia. This is most dramatically seen between North America and Africa during Pangeas initial rift some 240 million years ago. As lava cools on Earths surface it forms a variety of igneous rocks. Around 66 million to 30 million years ago it is believed Laurasia fragmented into the continents in the northern hemisphere we know today. Glacier grooves are the gaping trenches or landmarks carved out by movement of glacier. He provided evidence that mountain ranges occurring on opposite continents matched up pretty well when brought together. They write new content and verify and edit content received from contributors.

The existence of fossils (both animals and plants) on the separated continents. Aside from the congruency of continental shelf margins across the Atlantic, modern proponents of continental drift have amassed impressive geologic evidence to support their views. It has affected the global climate, the worlds geographical positions and the evolution of animals. With the development of modern science and physical proof that the Earths continents are moving, the evidence is overwhelming and it is hard to deny Wegners theory that the continents once formed a single land mass and drifted apart over a long period of geological time.

Corrections? Sedimentary rocks examination showed a change in climates, and the only possible explanations are continental drift or movement of the poles. Wegener, in his expedition, discovered glacier grooves in all the continents. Similar fossils were found on different continents. What are 4 evidences that support continental drift? Another term for subduction is slab pull which suggests that as the denser oceanic plate is subducted at a convergent margin, they become denser than the underlying mantle and pulls the rest of the plate behind it. What evidence supports the theory of ocean floor? Bringing together a large mass of geologic and paleontological data, Wegener postulated that throughout most of geologic time there was only one continent, which he called Pangea. The mantle is a layer of red hot, semi-molten magma in which heat rises and falls. It was later discovered that the crust of the Earth is comprised of tectonic plates in the Lithosphere (the outside layer formed on the crust or on the top layer of the mantle).
