What Is N For The Following Equation In Relating Kc To Kp? Evidence Alfred Wegener collected diverse pieces of evidence to support his theory, including geological "fit" and fossil evidence. Some of the fossil evidence discovered on the continents includes mesosaurus, lystosaurus, cygnognathus and glossopteris. Fossils of Mesosoaurs (freshwater aquatic reptiles) have been found on the continents of Africa and South America along with fossils of plant life providing more evidence that the continents were once joined and moved apart over time. If you take a look at the map before the continents drifted away, you find that Mesosaurus is located in the southern parts of Africa and North America. Another fossil that supports the hypothesis of continental drift is Glossopteris (glahs AHP tur us). This concept was an important precursor to the development of the theory of plate tectonics, which incorporates it. 2 What are some of the major pieces of evidence for the theory of plate tectonics? 2.

Which type of evidence was NOT used by Alfred Wegener to support his continental drift hypothesis? EVIDENCE FOR CONTINENTAL DRIFT Fossils of similar types of plants and animals in rocks of a similar age have been found on the shores of different continents, suggesting that the continents were once joined. 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. Almost all plate movement occurs in boundaries which lie between different plates. 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.

Despite being dismissed at first, the theory gained steam in the 1950s and 1960s as new data began to support the idea of continental drift. First samples of the deep ocean floor show that basaltic oceanic crust and overlying sediment become progressively younger as the mid-ocean ridge is approached and the sediment cover is thinner near the ridge. At convergent plates, oceanic and continental plates collide. Fossils and Mountain ranges were his evidences. The direction of their magnetization is the same as the direction of Earths magnetic field at the time and place of crystallization. This means it does not absorb, emit or reflect visible light, gamma rays, ultra-violet rays etc. continents look like puzzle pieces and seem to fit together.
