    Harry Hess helped with the plate tectonic theory. In 1945, when he was the commander of the USS Cape Johnson, he discovered that the sea-floor was spreading. While he was traveling around, he would leave the sounding equipment on that would take measurements of the sea floor. One of the main things he worked on is proving that the sea-floor is spreading. Harry Hess was born on May 27, 1906. He was born in New York. He got his PH.D. in the 1932 and his degree a year befor. He taught for one year at

  • Alfred Wegener And Continental Drift Essay

    866 Words  | 4 Pages

    Alfred Wegener and Continental drift It was 1912, and one man named Alfred Wegener was studying a map. He believed that the world looked as though it were one big puzzle, and that the continents could fit together. Then he thought that maybe, a very long time ago, they did. He hatched up a hypothesis. Simply put, his hypothesis proposed that the continents had once been joined, and over time had drifted apart. When the continents were together, he called the supercontinent Pangea. In order

  • Hotspot Theory Essay

    linear geography of the Hawaiian Islands is due to the movement of the Pacific plate over a stationary point of great heat from deep within the Earth. The great heat from this localized hotspot melts the Pacific plate above the hotspot and the spreading seafloor along the plate boundary pushed over the rocky crust. Magma was produced from the melting rock of the Pacific plate. The magma rise through the mantle and the crust as a thin thermal plume because magma is less dense than the solid rock of the

    The Cambrian Period is the first geological time period of the Paleozoic Era. This period lasted about 53 million years and marked a dramatic burst of Evolutionary changes in life on Earth, known as the "Cambrian Explosion. Plant and Animal Life • In the Cambrian period life was in the oceans and some of variety of microscopic plants were in the oceans. Many Early Cambrian invertebrates are known only from "small Shelly fossils". • There were a variety of microscopic marine plants like the Margarita

  • Explain Wegner's Theory Of The Continental Drift

    844 Words  | 4 Pages

    According to the textbook, Alfred Wegner proposed the idea that the continents were drifting across the globe. He called this idea the continental drift. He had the idea that the continents were once together forming one big landmass named Pangaea. As Pangaea developed it caused the continent to break apart, and drift to their present locations. To be able to prove this idea however, he had to have evidence to show it was true. If I could travel back in time to help Wegner prove his idea to be true

    rocks are not found on the sea floor that could be attributed to the dynamics of nature. One of them is because the sea floor is constantly changing thanks to seafloor spreading. So, the seafloor now is not the same as it was years ago. Seafloor spreading happens because of the earth’s plates constantly moving meaning the rocks on the seafloor will soon be shifted inward toward the mantel or shifted to another side. 2. The three types of plate convergences are convergent, divergent and transformative

He made important scientific contributions to the recognition of impact structures, particularly of ancient, eroded impact scars on Earth. Dietz was educated at

  • How Does Plate Tectonics Affect The Earth

    1026 Words  | 5 Pages

    Throughout geologic history, tectonic plate boundaries have diverged, converged and transformed the Earth, causing the surface of the Earth to be in a constant state of change. Plate tectonics, at present, is observed only on the Earth and “refers to a particular mode of convection in a planetary mantle, which is made of silicate rocks” (Korenaga 2012, p. 87). The lithosphere of the Earth is divided into plates which move at different velocities over the mantle, with much of the Earth’s seismic and

    The other part of the Earth consists of rigid plates which is called the lithosphere plates. They are moving relatively to each other. The moving of lithosphere plates is called plate tectonics. The idea of plate tectonics begin in 1600. Little significance was given to this notion till 1915 when Alfred Wegener, Germany meteorologist and geophysicist wrote a book entitled The Origins of Continents and Oceans. He had read about the similarities in the American and European fossils and become interested

    up the Earth’s crust (van Dover, 2000; Tivey, 2007; Martin et al., 2008). As the plates are pulled apart by tectonic forces, hot soft rock from the deep Earth emerges to fill the fissure. As the generated ocean crust laterally moves away from the spreading-axis, the age of the crust and the depth of the sediment cover increase systematically (van Dover, 2000). Therefore, different types of hydrothermal vents occur at different areas of the ultramafic sea floor. The simplest of these are the columnar

    to the theory that the earths lithosphere is divided into large rigid blocks that are floating on semi fluid rock and are thus able to interact with each other at their boundaries and to the associated theories of continental drift and sea floor spreading. There are a few handfuls of major plates and dozens of minor plates. Seven of the major plates are named for the continents, such as African, Antarctic, North American, Eurasian, Indo Australian , Pacific and South American. Plate Tectonics explains

    plate tectonics. The movement of Earth's tectonic plates formed Gondwana and broke it apart. The tectonic plates move as a consequence of mid oceanic ridges where adjacent plates are forced apart in different directions. Convection currents, seafloor spreading and rift valleys also drive the movement of the Earth’s plates. When Gondwana drifted apart, Antarctica, South America, Africa and Australia moved into the southern hemisphere and the Arabian Peninsula and the Indian Subcontinent moved into

    John Tuzo Wilson is a crucial importance in advancing the plate tectonics theory. Wilson had known Henry Hess in the late 1930s, when he was studying for his doctorate at Princeton University. Wilson suggested that the Hawaiian and other volcanic island chains may have formed because the movement of a plate over a stationary “hotspot” in the mantle. Another important contribution to the development of the plate tectonics theory was published two years later. Wilson proposed that there must be a third

    Birth of Plate Tectonics Plate tectonics is a scientific theory, coined in the 1950s, to explain the large-scale motion of Earth’s lithosphere (the outermost shell of planet Earth). This theory is based on the idea that Earth’s lithosphere is divided into several “plates” that move across the Earth’s surface, relative to each other, gliding over the mantle. The theory of plate tectonics was developed between the 1950s through the 1970s. It is basically the modern version of the theory of continental

    troposphere, which is the cause of the cooling in the atmosphere. Most of the particles within this dark cloud will fall out of the atmosphere and convert into rain within a few hours. Although, some of the smallest particles travel into the stratosphere, spreading over the earth and cause cooling over large areas for some months. Volcanoes have also made a contribution towards global warming over the last millions of years. This is due to the amount of carbon dioxide and water vapour that is emitted each
