Finding fossils of the Mesosaurus on the southern hemispheres of both continents is a further indication that the two continents were once together and later drifted apart. 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. What evidence did Alfred Wegener use for his hypothesis? Continental drift is a theory originally proposed by Alfred Wegener, who believed the continents were once one large continent known as Pangaea that later separated into several continents. Fossil records are strong evidence that the continents do drift. When plates drift away from each other, there is formation of new crust at divergent boundaries. Interest in continental drift increased in the 1950s as knowledge of Earths geomagnetic field during the geologic past developed from the studies of the British geophysicists Stanley K. Runcorn, Patrick M.S. What types of fossils were used as evidence for continental drift? Glossopteris - plant remains found in South America, Australia, Asia and Africa.

Laurasia contained the land masses in the northern hemisphere such as North America, Europe and Asia. Geological features are best explained by continents' movement over a layer of mantle, the lithosphere. The rest of the earth was covered with one huge ocean. 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. 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. The following piece of evidence represents matching geologic provinces in Africa and South America. There is variety of evidence that supports the claims that plate tectonics accounts for (1) the distribution of fossils on different continents, (2) the occurrence of earthquakes, and (3) continental and ocean floor features including mountains, volcanoes, faults, and trenches.

Molten rock material from Earths mantle rises upward to the crests, cools, and is later pushed aside by new intrusions. 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 . The four pieces of evidence for the continental drift include continents fitting together like a puzzle, scattering ancient fossils, rocks, mountain ranges, and the old climatic zones' locations. Evidence supporting the continental drift theory. Continental plates are 30km-70km thick whereas the thinner oceanic plates are only 5km-10km thick.

What are the effects of light pollution on animals? Studies by Runcorn of the remanent magnetism in suitable rocks of different ages from Europe produced a polar wandering curve indicating that the magnetic poles were in different places at different times. Wegener also provided evidence of continental drift by looking at the physical shape of continental coastlines. 6 pieces of evidence for continental drift. Wegeners theory of continental drift states that the existing continents of the earth were once glued together forming a super landmass. Wegener, in his expedition, discovered glacier grooves in all the continents. 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. Terms of Use, Evidence in Support of the Continental Drift: Analytical Essay., Evidence in Support of the Continental Drift: Analytical Essay [Internet]. 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).

Several types of evidence supported Hess's theory of sea-floor spreading: eruptions of molten material, magnetic stripes in the rock of the ocean floor, and the ages of the rocks themselves. He proposed that the continents were not stationary, but actually moving or drifting away from one another. He was limited by the technology of his time and more evidence to support his claim wasnt available till scientific technology improved and evidence was found of plate tectonics. Continents fit like a puzzle, climate clues, fossil clues, and rock layers or formations. Today we know that the continents rest on massive slabs of rock called tectonic plates. The theory of continental drift was supported by the theory of plate tectonics, which has been explained elaborately in Section 6. 4 What are 5 pieces of evidence of continental drift?
