In 1937 Alexander L. Du Toit, a South African geologist, modified Wegeners hypothesis by suggesting two primordial continents: Laurasia in the north and Gondwana in the south. Another piece of evidence is that fossils of plants, animals and invertebrates have been found on separate continents. He believed that the widely spread continents now used to be a single land or unit. 2.

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. What evidence supports the theory of continental drift? Evidence for Continental Drift It has been noted that the coastlines of South America and West Africa seem to match up, however more particularly the terrains of separate continents conform as well. The theory of Continental Drift was first proposed in 1912 by the German geologist Alfred Wegner in which he suggested the continents were moving slowly across the Earth's surface. Rock Correlation. Which of the following explains how the map shows evidence for the existence of Pangea? First, they theorized that separate species developed identically across the far-flung continents, a notion that was highly unlikely. 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. 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. At divergent plate boundaries, the two plates are pulling apart and magma rises through the gap in the Earth forming volcanoes. The first truly detailed and comprehensive theory of continental drift was proposed in 1912 by Alfred Wegener, a German meteorologist.

They based their idea of continental drift on several lines of evidence: fit of the continents paleoclimate indicators truncated geologic features and fossils. As the plates move away from the flanks of the ridges, they carry the continents with them. It seems likely, though it is still unproven, that this breakup of a single landmass and the drifting of its fragments is merely the latest in a series of similar occurrences throughout geologic time.

It suggested that those land areas had in the past been connected. Fossil records are strong evidence that the continents do drift. Late Paleozoic sedimentary rocks often contain extensive coal seams that were used to support the existence of Pangaea. 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. 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.

Evidence for Continental Drift. It is important to know that the following specific fossil evidence was not brought up by Wegener to support his theory. By basing it on evidence, Wegener stated that the mesosaurus can also be found in other continents. However, these different paths are reconciled by joining the continents in the manner proposed by Wegener. 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. It has affected the global climate, the worlds geographical positions and the evolution of animals. EVIDENCE FOR CONTINENTAL DRIFT There are various examples of fossils found on separate continents and in no other regions. He provided evidence that mountain ranges occurring on opposite continents matched up pretty well when brought together. It was hard for Wegner to back his theory as he was unable to explain how the continents moved. Volcanoes are distributed randomly on every continent. He suggested that Pangaea broke up long ago and that the continents then moved to their current positions.
