Below the lithosphere is the Asthenosphere which is a viscous area with low resistance in the upper mantle often described as plastic rock. One of the strongest pieces of evidence is Continental break up/fit, this is the idea that the continents were once joined together. Genetics. Finding identical or similar fossils in areas separated by vast distances were some of the first clues that scientists used to reconstruct past plate movement. Do now: Draw a convection current and explain why this happens? In addition, South America and Africa looked like they could fit together like puzzle pieces. On top of that, Lystrosaurus is situated in Antarctica, India, and Africa according to the modern map. This was based on the evidence of fossils that he gathered. A graphic of Gondwana. According to the latter hypothesis, Earths surface, or lithosphere, is composed of a number of large, rigid plates that float on a soft (presumably partially molten) layer of the mantle known as the asthenosphere. Some of the fossil evidence discovered on the continents includes mesosaurus, lystosaurus, cygnognathus and glossopteris. 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.

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. Subsequent plate movements averaging about 2 cm (0.8 inch) per year have taken the continents to their present position. The fact that the seeds would have been unable to be blown or floated to these continents proves that these continents were once together. 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). Blackett, and others. 4 What are 5 pieces of evidence of continental drift? Answer (1 of 3): Continental drift is not a theory, it is a measured fact. (It doesnt.) An example of this is the earliest known reptile, the mesosaurus. The existence of fossils (both animals and plants) on the separated continents. As the plates move away from the flanks of the ridges, they carry the continents with them.

If you take a look at a map of the earth today, you will see the current locations of broken land masses that constitute the earth. As the divergent plates move apart and new magma rises from the mantle it will record the current alignment of the North Pole. Over time, the landmass broke and drifted away and is still drifting to this day. 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.

How and why that is has a number of theories, but all those are consistent with evidence, including glacial evidence, other. Fossil records are strong evidence that the continents do drift. As the plates pulled apart from each other millions of years ago it caused earthquakes which led to magma rising from the mantle and erupting through the crust forming the Mid Atlantic Ridge as it solidified, this is called sea floor spreading as it is an example of two oceanic plates pulling away from each other. In 1908 Frank B. Taylor of the United States invoked the notion of continental collision to explain the formation of some of the worlds mountain ranges.

Some Southern Hemisphere geologists, particularly in South Africa, responded with enthusiasm. . Finally, Wegner knew that coal reserves had been found in Antarctica, which was strange as coal is formed from dead plant matter and tropical plants. On the basis of all these factors, it may be assumed that the Americas were joined with Europe and Africa until approximately 190 million years ago, when a rift split them apart along what is now the crest of the Mid-Atlantic Ridge. The shores of Red Sea exhibits evidence of having undergone lateral displacement /Sea flow spreading 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. How to Market Your Business with Webinars? Destruction happens when one plate moves below the other at convergent boundaries. Biogeography. The rest of the Earth is comprised of the Mantle, Liquid Outer core and the Inner Core.
