In addition South America and Africa looked like they could fit together like puzzle pieces. The Earth is broken into lithospheric plates that move due to convection currents. The supercontinent was surrounded by water bodies, mainly oceans, and seas. However, he supported his theory by explaining the earth's geologic history. One of the first lines of evidence suggesting the existence of plate tectonics was the discovery of very similar fossils in rock masses separated by vast distances and by ocean expanses. Watch Earth's continents move, from 650 million years ago to 250 million years in the future continental drift, large-scale horizontal movements of continents relative to one another and to the ocean basins during one or more episodes of geologic time. Continental drift is defined as the motion of the earth's continents over a defined period of time. He discovered glacier groves in continents that were not cold enough to support snow formation in the present day. It will explore the theory of continental drift by Alfred Wagener and the more advanced and developed theory of plate tectonics and how it has affected the volcanic hotspots and also provides several predictions for the future of Australias volcanos. 1 What evidence supports the continental drift theory?

Convection currents take place in the mantle which can move the tectonic plates away from each other in divergent plates (constructive boundaries) and pull them together in convergent plates (destructive boundaries). Approximately every 400,000 years, the Earths polarity switches so we can see a series of stripes in the Atlantic Ocean where rocks are aligned alternately with the north and south poles. 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.
