Plate Tectonics And Its Effects On The World - 1718 Words

Maybe the most ideal approach to see how Pinnacles started is to envision that you are viewing a video shot somewhere in the range of 60 million years prior completion at the present time. Not wishing to see something that is milleniums-long, you accelerate the activity by keeping your finger on the quick forward catch. Regardless. At last regardless you know the story all around ok to rehash it. Plate Tectonics At the point when the video starts, the mainlands have the structure we know today; the vast majority of the world s extraordinary mountain reaches are set up, and the Pacific Ocean is so far inland that a large portion of California s beach front mountains don t exist. Yet, they are going to be conceived - on account of something many refer to as plate tectonics. Geologists trust that the world s hull is isolated into huge plates that fit together like the bits of a mammoth jigsaw riddle. These plates are thought to move persistently, for the most part on a level plane. As per geologic hypothesis, the plates meet in no less than three ways, and two of these are imperative to our story: subduction zones (where one plate moves underneath the other), and change limits (where the two plates grind past each other). At some point around sixty million years prior, when our video starts, the lighter-weight North American Plate started abrogating or subducting the denser Farallon plate, and as it did, its external edge went about as a bulldozer, gathering upShow MoreRelatedThe Theory Of Plate Tectonics1487 Words   |  6 PagesThe theory of plate tectonics says the lithosphere is split into different plates that move around on top of the surface of the Earth. Though it is just a theory geologic time, ocean trenches, seafloor spreading, mountains, vol canoes, and earthquakes are all examples of evidence that support the theory of plate tectonics. Geologic time shows sediment patterns in different layers of the Earth. Geologic time is separated in three main periods called the Cenozoic Era, the Paleozoic Era, and the MesozoicRead MoreEffects on Motion and Plate Techtonics Essay examples776 Words   |  4 PagesUniversity of Phoenix Material Effects of the Motions of Tectonic Plates Worksheet From Visualizing Earth Science, by Merali, Z., and Skinner, B.

The purpose of this paper is to identify plate boundaries. Compare and contrast ideas behind plate tectonics and the theory of the continental drift. There are many types of plate boundaries. Each one is unique in its own way. Below three of the primary types are described in detail. There are several natural events that occur as a direct result of plate boundary interaction.

These massive plates move underneath the surfaces of the oceans and the continents, producing earthquakes, volcanoes and uplifts. This paper will discuss the composition, movement and history of tectonic plates, the theory of plate tectonics and its history, and tectonic plates affect theRead MoreTectonic Plates and Their Movement655 Words   |  3 PagesThe world as we know it today is the result of a process that has taken million of years and is still ongoing today. The movement of the earth is considered to be one of the most interesting and at the same time debated subjects science deals with particularly because there have been numerous attempts to try to explain the creation of the earth, its morphology, and current evolution. The tectonic plates and their movement are the basis of seismology which tries to explain the way in which the mountainsRead MoreInc1 Science Rint Task 11255 Words   |  6 PagesScientific Concepts and the Natural World RINT Task 1 Western Governors University Free Powerpoint Templates Page 1 The Earth’s Plate Tectonics James Hutton was the first scientist to address the Earth was millions of years old, as well as alive and is continuously being formed. Charles Lyell popularized uniformitarianism, and believed the Earth was being shaped by slow moving forces. Alfred Wegener introduced the foundation for the theory of continental drift. Wegener was one of theRead MoreThe Theory Of Plate Tectonics And Continental Drift950 Words   |  4 PagesThe concept of plate tectonics is that the lithosphere, which is the higher layers of the Earth’s surface, is separated into a number of plates that float independently over the mantle and along the boundaries that initiate the development of new crust, the building of mountains, and the seismic movement that triggers earthquakes (Geosystems 340). Scientists have discovered that the landforms and geographic regions we know and live on today were formed when plate tectonics shift and create movementRead MoreEssay on Plate Tectonics Explained1398 Words   |  6 Pagesdensity of a fluid is related to its temperature. Hot rocks lower in the mantle are less dense than the cooler rocks above. The hot rocks rise and the cooler rocks sink because of gravity. Convection currents are thought to be the driving mechanism of plate movement. Convection currents cause convergent and divergent movements. When the rising part of the convection current rises it causes the upper mantle to move upward and in a lateral direction. This causes the mantle to split and new material to riseRead MoreThe East African Rift Valley1424 Words   |  6 PagesSeafloor spreading when new oceanic crust is being created where two tectonic plates are diverging from one another. One of the largest examples of this is the East African Rift Valley. â€Å"In simple terms, a rift can be thought of as a fracture in the earth s surface that widens over time, or more technically, as an elongate basin bounded by opposed steeply dipping normal faults† (geology.com). The East African Rift is a 3000 km long feature that began developing millions of years ago. The rift travels
