Write a 500- to 750-word explanation regarding the role of plate tectonics in the origin of igneous rocks. To begin‚ igneous rocks come from magma‚ and magma is related to plate tectonics. Magmas differ in composition‚ temperature and viscosity. This is a major identifier of igneous rocks‚ is that they were once molten and magma Plate tectonics are the theory that the Earth’s lithosphere‚ which is the outer rigid shell is composed of several different pieces‚ or “plates” that float on a ductile

Igneous Rock SCI245 July 20‚ 2011 CheckPoint: Igneous Rocks The answer to how igneous rocks are formed is given in their name; Igneous is Latin for “fire”. This basically means igneous rocks are cooled fire rocks from magma or lava‚ depending on where they cooled and formed. There are two categories of igneous rocks that also depend on where each was formed. Intrusive igneous rocks are igneous rocks that form when magma cools slowly and becomes solid underground. Extrusive igneous rocks are igneous

Ironically‚ they were doing the exact opposite. The Harding Administration was an extremely corrupt group of men that became severely diminished once the Teapot Dome Scandal had been discovered. It was one of the most greatest and most sensational scandal’s in the history of American politics before the Watergate Scandal (Cherny). The Teapot Dome Scandal took place in the United States from 1920 to 1923‚ during the administration of President Warren G. Harding. Secretary of the Interior Albert B. Fall

Metamorphic rocks are the transformation of the existing rocks‚ the protolith through the process of metamorphism. The Protoliths can be the igneous rock‚ sedimentary rock or any old metamorphic rock. Due to severe heat and pressure‚ the protolithis get various chemical or physical changes. These rocks create a huge part of the Earth’s crust and these can be classified by the mineral and chemical assemblage and by the textures. Examples of the metamorphic rocks are: slate‚ gneiss‚ schist‚ marble

A Genealogy of Rock Music Today‚ the term Rock Music brings about images of wild hotel parties‚ pyrotechnics‚ drugs‚ plane crashes and iconic frontmen. However‚ in order to form a real understanding of how rock music came to be the legendary style that it is today‚ we must understand its origins. Rock music is rooted deep in America’s most trivial times- in the songs of African American slaves- from the Mississippi Delta right up to the Mason-Dixon line‚ it is a simple musical styling that is

First off you should know what a rock cycle is. The rock cycle is a fundamental concept in geology that describes the dynamic transitions through geologic time among the three main rock types: sedimentary‚ metamorphic‚ and igneous. Rocks make rocks. The cycle begins within the core of the earth. The molten rock in the core of the earth is called magma. Once the rock is forced to the earth’s lithosphere or crust‚ the molten rock becomes lava and thereby begins its long journey of development

Is Peter the Rock? It is a significant position that divides the Christian religion. For nearly five hundred years‚ Catholics and Protestants have quarreled over the meaning behind a verse in the gospel of Matthew‚ "That thou art Peter‚ and upon this rock I will build my church" (Matt. 16:18‚ KJV). This essay will argue that the Apostle Peter is the rock in the sixteenth chapter of Matthew. It is apparent that Christ gave Peter primacy among the other disciples‚ declaring him the rock to which his

A joint is defined as a fracture in a rock between the sides of which there is no observable relative movement. They are present is most consolidated rocks of igneous‚ metamorphic and sedimentary origin. Joints may form as a result of either diastrophism or contraction. Description: (i) A series of parallel joints is called a ’joint set’. (ii) Two or more joint sets intersecting each other produce a ’joint system’. (iii) Two sets of joints nearly at right angles to one another‚ produced by the

Rocks are classified in order to communicate information about them. All classifications of limestones are arbitrary and they frequently overlap or do not fit ones particular needs. Since binocular microscopes or hand lenses are the tools that are commonly available to the explorationist‚ a practical classification should be based on descriptions using them. When these instruments are used‚ it is usually possible to identify the individual grains forming the rock. Thus most classifications require
