A metamorphic Rock can be formed by simply being under the earth’s surface‚ being exposed to extremely high temperatures and a huge amount of pressure from the layers of rock above. These rocks can be formed by tectonic processes‚ some which include‚ continental collisions (this is a process that causes friction‚ distortion and horizontal pressure). These rocks can also be formed when rock becomes heated rapidly by the intrusion of a hot molten rock‚ (called magma) and it comes from the earth’s interior

intrusive rocks harden slowly beneath the surface of the earth‚ and often form large mineral crystals within the rock. Granite is a good example of an intrusive rock.Porphyritic intrusive rocks have large crystals embedded in a matrix of smaller crystals. Pegmatite is the only porphyritic rock on the Science Olympiad list.Extrusive rocks harden quickly during a volcanic eruption and are usually smooth-grained. Basalt is the most common form of extrusive rock. |IgneousName |Classification|Description

Metamorphic rocks are originated within the earths crust. Metamorphic rocks are created when both pressure and heat meet at the right time. During metamorphosis the rocks do not melt the heat and pressure just change the make-up of the rock. There are two types of metamorphosis low grade and high grade. Low grade metamorphosis occurs at 400 degrees C and 400MPa‚ while high grade is anything above 400 degrees c and 400MPa. Once the temperature reaches a little over 600 degrees Celsius and over 600MPa

The rock cycle is very important to us because it explains the way the different types of rocks are formed on earth. The rocks currently visible on the Earth’s surface have moved through transition stages that transformed them from one form into another. The importance of the rock cycle lies in how it forms and recycles the various layers that make up the Earth. To do this‚ the cycle moves through three different stages that produce three different types of rock. Igneous rock makes up the foundation

The History of Punk Rock What comes to your mind when you hear the word “punk?” Do you think of a violent‚ attention-seeking young person‚ or do you think of a rebellious teenager who is trying to go against the mainstream society? “Punk is about being 16 and saying no.” According to Encarta Dictionary: English‚ punk is a youth movement of the late 1970s‚ characterized by loud aggressive rock music‚ confrontational attitudes‚ body piercing‚ and unconventional hairstyles‚ makeup‚ and clothing

in the 1950s‚ half of them would say rock n roll. In fact‚ to this day people still like to jam out on rock n roll. Rock n Roll was viewed in many point back then‚ and possibly a lot more. Some thought of it as a way to get pumped for anything‚ like a game or test. Other saw it as an enjoyable type of music that most people could agree on and talk about it. There were however‚ people who were against the music‚ especially Christians. They thought the

Metamorphic Rocks Axia College of the University of Phoenix Metamorphic rock is the transformation of an existing rock type in a process called metamorphism‚ which means change in form. Metamorphic rocks make up a large part of the Earth ’s crust and are classified by texture and by chemical and mineral assemblage (Murck‚ Skinner‚ & Mackenzie‚ 2008). Metamorphic rocks started out as some other type of rock‚ but have been substantially changed from their original igneous‚ sedimentary‚

The rock cycle involves of a chain of continual progressions through which earth materials change from one form to another over time. Some processes in the rock cycle happen over millions of years and others occur much more quickly. There is no real starting or completion to the rock cycle; however‚ it may be appropriate to begin investigating the rock cycle with magma (Bergman 2005). Magma‚ or molten rock‚ forms only at certain locations within the earth‚ mostly along plate boundaries. Magma crystallizes

The Dome of the Rock stands high above the city of Jerusalem‚ allowing for the sun to reflect off of the gold dome. It is known to most as a shrine in Jerusalem. It is known to most as The Quabbat al’Sakrah mosque. It is known to most that it rests on the Temple Mount. But what most do not know is that The Dome of the Rock is the earliest Islamic monument to have survived in its original form to this day. The Dome of the Rock‚ which has stood the test of time‚ is an important building in world

I Introduction Rock Music‚ group of related music styles that have dominated popular music in the West since about 1955. Rock music began in the United States‚ but it has influenced and in turn been shaped by a broad field of cultures and musical traditions‚ including gospel music‚ the blues‚ country-and-western music‚ classical music (see Music‚ Western)‚ folk music‚ electronic music‚ and the popular music of Asia‚ Africa‚ and Latin America (see Worldbeat). In addition to its use as a broad
