  • The Continental Drift Theory: The Aspects Of The Continental Drift Theory

    1593 Words  | 7 Pages

    Because according to the continental drift theory, ages ago, the continents today were a completed one piece and called Pangaea. (Sandner, 506-507) The continental drift theory is a theory first proposed by a German geologist and meteorologist Alfred Wegener in 1915. This theory suggests that parts of the Earth’s crust which are called continents were slowly drifting above a liquid core. He didn’t randomly come up with this idea with whim, there are actually some solid evidence to support this theory

  • Studying Plate Tectonics to Help in the Future

    Studying Plate Tectonics to Help in the Future Prior to World War II, humans were conformed with the idea that the Earth and its continents had been basically unchanged since the beginning of time. A German meteorologist, Alfred Wegener observed that the coastlines of the seven continents could be fitted together almost perfectly like a jigsaw puzzle. If fitted together, the geological dating the land would match as well as other geological features. He believed that this was more than coincidence

    geological issues such as the origin of oceanic crust. Plate Tectonics has a significant effect on all fields of geology because it helps explain many geological phenomenons. Figure1. Earth Plate 2.0 History Way back to 1915, scientist Alfred Wegener proposed his theory of “Continental Drift”, which clarified that the continents plowed through crust of ocean basin s. It helped explain why the outlines of many coast lines, such as South America and Africa looked like a puzzle when they fitted

    closely. Some geologists then suggested that the fit of the coasts was not an accident--that the continents were once joined and had subsequently drifted apart. None of the suggestions were taken seriously. In 1912, however, the German meteorologist Alfred Wegener investigated the fit of the Atlantic coasts more carefully than had his predecessors and grouped all the continents together into one great land mass, which he called Pangaea. He supposed that the mass began to break apart about 200 million years

  • Accepted and Discarded Knowledge

    1067 Words  | 5 Pages

    There have already been some facts or knowledge that people ones believed in, but suddenly someone has discovered a new fact that may contradict the previous fact everybody thought was right. In this essay I will consider some knowledge issues in two different areas of knowledge which I chose to do natural science and religion. The purpose of this essay is to distinguish between different accepted knowledge and try to investigate why some knowledge is discarded after finding something that contradicts

  • How The Importance Of Vaccines

    1262 Words  | 6 Pages

    Vaccines have always been an important pinpoint in medical history. The vaccines were an important factor in medicine, and the evolution of mankind. The vaccines were performed by a country doctor, Edward Jenner. Doctor Jenner inserted cowpox into a young boy, and noticed the boy was unaffected to the exposure of cowpox later on. Next, the doctor experimented with smallpox and realized that once the virus is injected the body is immune to the bacteria or virus. The smallpox was the world’s first

  • The Continental Thrift Theory And Plate Tectonics Theory

    1331 Words  | 6 Pages

    Background The continental drift theory and plate tectonics theory was first put forward by the German geologist and meteorologist Alfred Wegener at the beginning of the 20th century. He proposed that there was a single continental in 200 million years ago, and the Earth’s crust slowly separate to pieces by the centrifugal pseudo force because of the rotation of the Earth. On the basis of plate tectonics theory there are two components in the Earth which are lithosphere and asthenosphere, the upper

    Convergent boundaries, divergent boundaries and convection currents all examples of physical evidence that supports the theory of plate tectonics. Continental drift is the theory contrived by Alfred Wegener in 1912 that states that Earth’s tectonic plates are in slow constant movement. At the time he didn’t know how the continents moved. The theory was soon modernized in the 50’s and the theory of plate tectonics became was born. Plate tectonics

    environment was hot and dry. The environmental conditions were so extreme that the marine and terrestrial life forms were greatly affected. According to research the drastic climate change could have been caused by the formation of Pangaea. In 1912 Alfred Wegener while studying his theory of the continental drift, discovered Pangaea’s very existence. A combination of all of Earth’s landmasses joined together and covered 1/3 of Earth’s surface. Pangaea was f... ... middle of paper ... ...nder, C., Tsai

    depending on the plate boundary. These faults happen on tectonic plate boundaries, also known as fault lines, where two tectonic plates meet. Tectonic plates are what continents stand on, which are in fact slowly drifting apart. A theory proposed by Alfred Wegener, called the Theory of Continental Drift, says that the Earth’s mantle is a semi-solid, and the tectonic plates are floating on the mantle, and since the continents are on the plates, the continents drift with the plates. There are four main types
