When one scientist did calculations that assumed that these forces were strong enough to move continents, his result was that if Earth had such strong forces the planet would stop rotating in less than one year. Students will visit 6 stations, each describing a different piece of evidence. Which one among the continental drift pieces of evidences mainly proves that the Cape Mountains of South America and Africa line up perfectly before? Today, scientists think that several supercontinents like Pangaea have formed and broken up over the course of the Earths lifespan. Another important piece of evidence in the Continental Drift theory is the fossil relevance. See also how was society organized. Its fossils are found only in South Africa and South America. Holmes thought this could be like a conveyor belt. This indicates that these continents had to be once joined together because the extensive oceans between these land masses act as a type of barrier for fossil transfer. But a hypothesis is rarely accepted without a mechanism to drive it. Another indication of continental drift is tectonic activity and seafloor spreading. Some of the most dynamic sites of tectonic activity are seafloor spreading zones and giant rift valleys. Way the continents had remained fixed and the continents then moved to their positions!

In 1964, Bullard created a map using a computer program to find the right fit of the Atlantic margin and it proved to be quiet. The earths outer shell is composed of plates that move a little bit every year. Pangaea Wegener was convinced that all of Earths continents were once part of an enormous, single landmass called Pangaea. According to National Geographic, sea floor spreading and plate tectonics indicate that the continents do move or shift, which supports continental drift theory. The gold-bearing veins are in Brazil and it is obvious that the gold deposits of Ghana are derived from the Brazil plateau when the two continents lay side by side. The Hawaiian Islands were created by the Pacific Plate, which is the worlds largest plate at 39,768,522 square miles.

Continental drift describes one of the earliest ways geologists thought continents moved over time. Evidence from fossils glaciers and complementary coastlines helps reveal how the plates once fit together. This indicates that these continents had to be once joined together because the extensive oceans between these land masses act as a type of barrier for fossil transfer. What are six pieces of evidence for the continental drift theory? The theory he believed was that there was a super continent called Pangaea. There are four types of boundaries between tectonic plates that are defined by the movement of the plates: divergent and convergent boundaries, transform fault boundaries, and plate boundary zones. Continental drift is the hypothesis that the Earth's continents have moved over geologic time relative to each other, thus appearing to have "drifted" across the ocean bed.

In the process of seafloor spreading, molten rock rises from within the Earth and adds new seafloor (oceanic crust) to the edges of the old. Set forth in 1912 by Alfred Wegener, a geophysicist and meteorologist, continental drift also explained why look-alike animal and plant fossils, and similar rock formations, are found on different continents.

The east coast of South America and the west coast of Africa seem to fit together like pieces of a jigsaw puzzle, and Wegener discovered their rock layers fit just as clearly. Scientists have long noticed the similarity between the two coastlines, but it was not until the 20th century that evidence could support a theory that the continents were once connected. Therefore, the continents must have been joined at least one point in time in order to maintain the Glossopteris wide range across the southern continents. Alfred Wegener published his idea that the continents had been joined as a single landmass, which he called Pangaea, about 300 million years ago.
