Plate tectonics are one the most intense forces that form Earth and can cause cataclysmic events earthquakes, volcanoes and tsunamis.The Earth’s surface isn’t a solitary mass but is instead comprised of numerous plates, each one sliding over the planet’s mantle. Despite the fact that, most of the time these plates move steadily and only create changes over a span of millions of years, occasionally, however, two plates will suddenly move with respect to each other, making the Earth’s surface subject to cataclysmic events. Proof suggesting the presence of plates tectonics are the location of fossils, the shape of the continents and the age of rocks at mid-ocean range.There are numerous cases of fossils found on isolated land masses and nowhere else, implying the continents were once joined. If Continental Drift had not occurred, the only other possible conclusions would be that the species evolved independently on separate continents, conflicting with Darwin’s theory of evolution or they swam to continents near by and produced a second population. One example is an extinct reptile called Mesosaurus, which thrived 275 million years ago. This fossil can be found in both southern Africa and near the southern tip of South America. Today, these territories are isolated by almost 5,000 miles of Atlantic Ocean. Although Mesosaurus was a ocean abiding animal, it occupied shallow coastal waters and was unlikely to have crossed such an immense sea.People began perceiving how continents would be able to fit together, dating back to when maps were first created. For instance, people noticed that South America precisely fits into Africa. It’s known that most continental masses can fit together almost like a jigsaw puzzle. Truth be told, we also know that the continents were all previously combined as one land mass, the supercontinent of Pangea. Alfred Wegener, a geophysicist and meteorologist, was the first to propose the idea of continental drift and plate tectonics. He trusted that Pangea had existed in the past, broke up about 200 millions years prior, and had moved into the position its in now. This theory was controversial all the way up to the 1960s, when it started to become broadly acknowledged. Seafloor spreading is a process in which the sea floor spreads apart along both sides of a mid-ocean ridge as new crust is added. Subsequently, the sea depths move like conveyor belts, carrying the continents along with them. Seafloor spreading was introduced by a geophysicist named Harry H. Hess in 1960. By the utilization of sonar, Hess could map sea depths and discovered the mid-Atlantic ridge. He likewise discovered that the temperature close to the mid-Atlantic ridge was hotter than the surface far from it. He trusted that the high temperature was due to the magma that spilled from the ridge. The Continental Drift Theory is upheld by this speculation on the shift position of the world’s surface.Plate tectonics are vital to comprehend the manner by which our planet advances. They are in charge of a significant number of the structures and features that exists in our planet. Whenever sea floors spread, volcanoes detonate, or mountains ascend, plate tectonics are the driving force. Evidence such as the location of fossils, the shape of the continents and the age of rocks at mid-ocean range is the reason why this theory has reached such a high level of scientific acceptance.
