Plate Tectonics Essay

...INTRODUCTION Plate tectonics The large scale motions of the earth’s lithosphere are describe by a scientific theory called plate tectonics which explains that Earth's outer layer is made up of plates, which have moved throughout Earth's history. The theory was developed during first decade of 20th century (by a famous advocate Alfred Wegener) on the older concept of continental drift and was accepted by many geoscientific communities. There are currently seven major and many minor plates are present in the case of earth. These plates move in relation to one another at one of three types of plate boundaries: convergent or collisional boundaries; divergent boundaries, also called spreading centres; and conservative transform boundaries. Activities like earthquakes, volcanic activity, mountain building and oceanic trench formation occur along these plate boundaries and the lateral relative movement of the plates varies 0-100 mm annually. Relation between plate tectonics and mountains: Mountain formation processes are associated with large scale movements of tectonic plates. The formation of mountain ranges occurs by means of lateral movements as opposed to vertical ones. Mountain formation is related to plate...

plate tectonics Essay

...Plate Tectonics Ever since the beginning on time, Humans believed the ground is solid and immobile. But this is not true whatsoever. The Earth is every-changing and continually in motion. The stability of the Earth is not at all what we think it is. Thinking about the rotational axis of the Earth, and possibly of what the Earth may become at a certain point in time, has a great influence on understanding all aspects of living things, either in the past, present, or future. The study of Plate tectonics is accredited to most of the creations of Mountain Ranges, the drifting of continents, earthquakes, and volcanic activity. Plate tectonics and mountains also play a big part in the geological features of our planet or any planet for that matter. Geophysics, which studies the physics of the Earth, has led to many important findings about the Earth and how it is made. Seismologic studies of planet Earth have revealed new information about the inside of the Earth that has helped to give new openings in understanding plate tectonics. The Earth is made of several significant layers. Each one of these layers has its own properties. The crust is the outermost layer of the Earth. The crust is made up of the oceans and continents. The crust has a fluctuating thickness, being thirty to seventy-five kilometres thick in the continents and ten to fifteen kilometres thick...

Plate Tectonics and Pacific Plate Essay

...below) Tectonic plates of the world. The Pacific Ring of Fire (or just The Ring of Fire) is an area where a large number of earthquakes and volcanic eruptions occur in the basin of the Pacific Ocean. In a 40,000 km (25,000 mi) horseshoe shape, it is associated with a nearly continuous series of oceanic trenches, volcanic arcs, and volcanic belts and plate movements. The Ring of Fire has 452 volcanoes and is home to over 75% of the world's active and dormant volcanoes.[1] It is sometimes called the circum-Pacific belt or the circum-Pacific seismic belt. Eruption of Mount St. Helens on July 22, 1980. About 90%[2] of the world's earthquakes and 81%[3] of the world's largest earthquakes occur along the Ring of Fire. The next most seismic region (5–6% of earthquakes and 17% of the world's largest earthquakes) is the Alpide belt, which extends from Java to Sumatra through the Himalayas, the Mediterranean, and out into the Atlantic. The Mid-Atlantic Ridge is the third most prominent earthquake belt.[4][5] The Ring of Fire is a direct result of plate tectonics and the movement and collisions of lithospheric plates.[6] The eastern section of the ring is the result of the Nazca Plate and the Cocos Plate being subducted beneath the westward moving South American Plate. The Cocos Plate is being subducted beneath the Caribbean...

Plate Tectonics Essay

...Plate tectonics (from the Late Latin tectonicus, from the Greek: τεκτονικός "pertaining to building")[1] is a scientific theory that describes the large-scale motions of Earth's lithosphere. The model builds on the concepts of continental drift, developed during the first few decades of the 20th century. The geoscientific community accepted the theory after the concepts of seafloor spreading were developed in the late 1950s and early 1960s. The lithosphere is broken up into tectonic plates. On Earth, there are seven or eight major plates (depending on how they are defined) and many minor plates. Where plates meet, their relative motion determines the type of boundary: convergent, divergent, or transform. Earthquakes, volcanic activity, mountain-building, and oceanic trench formation occur along these plate boundaries. The lateral relative movement of the plates typically varies from zero to 100 mm annually.[2] Tectonic plates are composed of oceanic lithosphere and thicker continental lithosphere, each topped by its own kind of crust. Along convergent boundaries, subduction carries plates into the mantle; the material lost is roughly balanced by the formation of new (oceanic) crust along divergent margins by seafloor spreading. In this way, the total surface of the globe remains the same. This...

The Impact of Plate Tectonics on the Caribbean Essay

...The Impact Of Plate Tectonics on the Caribbean * The Caribbean Plate is a mostly oceanic tectonic plate underlying Central America and the Caribbean Sea off the north coast of South America. * Volcanic activity in the Caribbean itself, as distinct from Central America, is largely limited to the eastern Caribbean. Here, the Caribbean plate, moving approximately west to east, meets the North American plate, which is moving approximately east to west. This creates what is known as a seductions zone, where the North American plate is driven below the Caribbean plate. The rock of the North American plate melts, but as it is less dense than the molten rock of the earth's mantle, it rises, forcing its way through weaknesses in the earth's crust. The points where this molten rock appears on the Earth's surface are volcanoes. * Roughly 3.2 million square kilometers (1.2 million square miles) in area, the Caribbean Plate borders the North American Plate, the South American Plate, the Nazca Plate and the Cocos Plate. These borders are regions of intense seismic activity, including frequent earthquakes, occasional tsunamis and volcanic eruptions. * Plate tectonics give rise to fold mountains, earthquakes, volcanoes, island arcs...

...Discuss the view that the impact of earthquake hazards depends primarily on human factors (40 marks) Earthquakes are an example of seismic activity caused by the build-up of tension at the three types of plate boundaries: destructive, constructive and conservative. The pressure is suddenly released as the plates jerk past each other, sending out seismic waves from the focus that travel through different parts of the earth. The movement of convection currents within the Earth’s mantle causing the crust to become mobile which creates the different types plate margins, makes the cause due to physical factors. However human activity is suggested to be the cause of some minor earthquakes, for instance the building of large reservoirs where the water stresses the surface rocks or the subsidence of deep mine workings. The seismic waves cause the initial effect of ground shaking. The severity of this will depend upon the nature of the event such as the magnitude of the earthquake, the depth of the focus and the local geological conditions. The scale of these conditions will determine the risk to the hazards present, so the larger the event the greater the impacts. Physical factors such as the location of the epicentre and the presence of land can also determine the different impacts, but I feel that human factors play a further critical decider in the type of effects, as each earthquake happens in a different environment which has...

plate tectonic press release Essay

... Plate Tectonics Press Release GLG/101 July-27, 2014 Kathy Howard Plate Tectonics Press Release How can the families of Los Angeles be prepared for an earthquake? This is a very important question that haunts us every day, because we don’t always know when they are coming and how bad they will be. I am Donte Lindsey and I am the director of Earth Preparedness of Los Angeles. With any type of danger the first thing you need to be prepared with is knowledge. Today we will discuss the hazards that are associated with earthquakes here in the city of Los Angeles, the causes and the plate tectonics and faults. For many years people always called southern California Americas Promised Land because of its beautiful weather, beaches and its film industry. Now with 13 million habitants it’s been looked at as hazard city. “Not only does the San Andreas Fault, marking the conservative margin between the Pacific and North American plates, cross Southern California, but LA was built across a myriad of transform faults” ("Case Study For Multiple Hazards; Los Angeles, California, Usa.", 1999). These include the Santa Monica fault, the San Fernando fault, and the Northridge/Santa Barbara fault. Although the most violent earthquakes are predicted to occur along the San Andreas Fault, earth movements frequently occur along most of the lesser known faults....
