Fossils - certain fossils preserved in rocks of the same age but from different continents. It was first suggested by Abraham Ortelius in 1596, and Alfred Wegener completed its development. Today, the theory of continental drift has been replaced by the science of plate tectonics. This could be explained either by the migration of the magnetic pole itself (that is, polar wandering) or by the migration of Europe relative to a fixed pole (that is, continental drift).

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. ! 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. 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. 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. In this essay I will describe more in-depth about the Earths dynamic structure and how plate tectonics affected biotas. More evidence was needed, and it came from the Earth's magnetism. Continental drift is the suggestion that over long periods of geological time, the continents of the Earth have moved apart from each other and had once formed almost one single land mass known as Pangaea. Government programs to settle the land 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.

Some Southern Hemisphere geologists, particularly in South Africa, responded with enthusiasm. He suggested that Pangaea broke up long ago and that the continents then moved to their current positions. 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. Background on the Ground Alfred Wegener was the developer of a new theory of the earth's surface called continental drift, and he was an adept investigator, but he passed away in 1930 with his. 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. The hypothesis addresses how the continents and oceans are distributed. As molten rock rises from the Earth, it forms new crust between the plates.

What are the 5 evidences of continental drift? 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. An example of a convergent plate boundary is the Pacific Plate and the Eurasian plate. The direction of their magnetization is the same as the direction of Earths magnetic field at the time and place of crystallization. Which statement would best support Wegeners hypothesis?
