...History of Rocks As explained in Visualizing Geology, rocks are the words that tell the story of Earth’s long history and minerals are the letters that form the words. While this report will not be discussing minerals, it will introduce the history of rocks and how they are affected by plate tectonics. The focus of this report is on two of the three types of rocks, igneous and metamorphic rocks. Plate tectonics plays a key role in the life of these types of rocks. So let’s get started by first explaining igneous rocks. Next metamorphic rocks will be explained. Lastly, plate tectonics and the affect this theory has on both types of rock. Igneous rocks are rocks that form from magma that has been cooled and solidified. Igneous rocks have a structure that is made up of crystals. Igneous rocks are placed into to categories. As stated before, rocks are created by minerals. The process of a liquid forming into a solid is known as crystallization. The first category is extrusive or volcanic. These rocks are cooled on the top of the Earth’s surface. Extrusive rocks have microscopic crystals because it cools relatively quickly and the crystals do not have a chance to become as large as they could be. Extrusive rocks are formed by lava cooling. The second category is intrusive or plutonic. These rocks are cooled below the Earth’s surface. Intrusive rock is formed by the cooling of magma. Intrusive rocks have crystals that can be seen with the naked eye because the cooling process is relatively...

...Level Material History of Rock Worksheet Leah Bechtel 12/09/2012 SCI/245 Robert Dillon Write a 500- to 750-word explanation regarding the role of plate tectonics in the origin of igneous rocks. The role of plate tectonics in the origin of igneous rock is extremely important. Igneous rock is formed from magma that reaches the continental and oceanic crust or through hot spots that are around the world. There are three different places where igneous rocks can form; where the lithospheric plates pull apart at mid ocean ridges, where plates come together at seduction zones, and where continental crust is pushed together making the crust thicker and allowing it to heat to a melting point. The word igneous comes from the Latin word for fire, igneous rocks start off as a hot, fluid material which is usually erupted from the Earth’s surface as lava, or magma at shallow depths or deep depths. Magma is a mush like material that can carry a load of minerals, but people often think of lava and magma as a liquid like material of molten metals. The three types of igneous rocks are extrusive, intrusive and platonic rocks. Extrusive rocks are rocks that form and cool on the crust of the Earth whether it is on the continental crust or the oceanic crust. Extrusive rocks cool quickly, within a few seconds to months and they have invisible or very small grains; extrusive rocks have an aphanitic texture. Intrusive rocks are rocks that form within already existing rocks causing sills and...

...THE HISTORY OF ROCK AND POP "POP" is short for "popular" and there has always been popular music. But until the 1950s there wasn't a style of music just for young people. That all changed when rock and roll began. Since then, hundreds of styles and stars have come and gone. Musical technology has changed a lot too. Here, we look at the highlights of rock and pop's forty-year history. The '50s Rock and roll began in America. Some of its first big stars were black - for example Chuck Berry, Fats Domino and Little Richard. They brought traditional "rhythm and blues" to a big new TV audience. Then, white singers began to copy them. One of the first was Bill Haley. He and his band, The Comets, recorded an early rock and roll classic, "Rock Around The Clock". There were other white "rockers", too, like Jerry Lee Lewis and Buddy Holly. But the most popular of them all was Elvis Aaron Presley. Elvis wasn't like the American singers of the '40s and early '50s. He wasn't neat, sweet and safe. He was rough, tough and dangerous. His music was dangerous, too. He called himself "The King of Rock and Roll" and played an electric guitar. Teenagers all over the world fell in love with this new style. They bought millions of his records. Suddenly the younger generation didn't just have money, cars and televisions - they had a hero, too. The '60s Pop exploded in the '60s. After Elvis, hundreds of new groups and singers appeared. In Britain, two groups quickly became more...

...Use the following table to compare extrusive and intrusive rocks. Describe and compare each type in at least 150 words. Extrusive Rock Intrusive Rock Extrusive igneous rocks are formed at the crust's surface as a result of the partial melting of rocks within the mantle and crust. Extrusive Igneous rocks cool and solidify quicker than intrusive igneous rocks. When lava is exposed to the atmosphere or water outside of the earth, this causes the lava to cool very rapidly in comparison to intrusive rocks. This rapid cooling does not allow the rock time to form large crystals in the way that intrusive rocks do. Extrusive rocks have a fine-grained texture known to geologists as aphanitic, because the mineral crystals present within the rock are very small. It is much more difficult to distinguish between the different types of extrusive igneous rocks than between different types of intrusive igneous rocks because the minerals are mostly fine-grained. Examples of extrusive igneous rocks are basalt and obsidian. Rhyolite is the extrusive counterpart of granite due to its high silica concentration, but fine-grained texture. One form of igneous rocks, intrusive rocks, derives directly from magma and solidifies within the earth. Since intrusive rocks are within the earth, they cool very slowly, taking anywhere from thousands to millions of years to cool enough to completely solidify. The cooling rate of intrusive rocks enables the crystals to form that are visible to the naked...

...PBS Videos 6-10 In video 6: “Blues in Technicolor”, we learned a lot about how LSD played a major role in rock music. One of the popular figures who promoted LSD was writer Ken Kesey. One of the most prominent groups during this era of rock music was “The Grateful Dead”, who originated in San Francisco, and were heavily into improvising. There was a neighborhood at this time where the early psychedelic bands lived, and this place was called Haight Ashbury. This era also saw what was to be the end of the Beatle’s touring days, because they decided that they would rather experiment with new directions in the music industry. One of the first bands out of San Francisco to have success with pop was “The Jefferson Airplane”. Another major accomplishment from this era was in 1968 when LPs outsold 45s for the first time ever. This era of strong hippy movement which lasted a long while, came to an end by late 1969. In video 7, we learned about “The Velvet Underground” band and how they were associated with famous pop artist Andy Warhol. This same band which was popular in the 1960s, was also a major influence to Jim Morrison. Another extremely popular band during this era was “The Doors”. “The Doors” were major influence to “Iggy Pop”, along with “The Velvet Underground”. One of the most prominent figures in rock during this time was Alice Cooper, and his band. His band was really the definition of cultureless American society. Alice Cooper gained a lot of press for an...

...The history of Bangladeshi rock music started in 1960 when a handful of self-taught musicians got together to create original music tracks. Their efforts resulted in the birth of the "Bangla Rock Scene". Among the pioneering groups in the late '60s were bands such as Windy Side of Care (Rafique Mazhar Islam Saju and Rafi Omar) (Ex-Iolites), The Lightnings, Rambling Stones, Ugly Phases and Insex Dui. They didn’t have the privilege of expensive instruments or sound systems, which present-day rockers now take for granted.[1] In 1963, "Zinga Goshty" was the first[citation needed]Orchestra Band in Bangladesh, formed in Chittagong by a young group of students of Chittagong College. [2] Azam Khan (Uchharon) a.k.a. "the Legend", a.k.a. "the Imaginative Composer", emerged around early and late 70s. Happy Akhand's "Abar Alo Elo Je Shondha" is a well known song. His premature death was a big blow to all of the musicians who were influenced by Happy's passion for music. His contemporaries include some popular figures such as late Firoze Shahi, Ferdaus Wahid and Fakir Alamgir. Among the old bands there are many bands that are still active, such as is Souls (1970), Feedback (1976), Miles (1978), and others. [3] Progression (1980s) While the early phase of Bangladeshi rock is marked by romantic songs and mellow tunes, the scenario began to change in the '80s. "Warfaze" was a progressive rock band of the country in this period. "Feedback" was another band in the `80s with their album...

...Peter Clark Professor James Smethurst AFROAM 151 December 5, 2012 The History Of Rock and Roll: Copyright Not Included The history of black America is one filled with exploitation and abuse. Time and time again we see the “cultural rape” of the black community. Whether it be style, lingo, or music white culture has been “borrowing” from black culture since the early history of the United States. It is so obvious it almost passes unnoticed. For example the handshake has largely been replaced in youth culture by a dap or a fist pound, both remnant of black culture in the 60’s. Even hello has been replaced with “yo” an interjection made popular in the black vernacular. One cultural phenomena that has been largely covered up as African-American in origin. The history of rock and roll is long and intricate drawing its roots from early American R&B, among other places. While most of the true innovators of rock music have been widely overlooked, white musicians have been profiting greatly off of the innovations made in music by black recording artists, specifically in the arena of rock and roll. It is widely accepted that rock music has its roots in the american blues. The history of the blues dates all the way back to slave plantations. This genre comes specifically from African-American folk music. Julio Finn the author of The Bluesman stated that: [White blues performers] can never be bluespeople...because the blues is not something they live but something they...

...Shosanna Spill Tricia Swoope ENG 112 03 July 2010 Rock Music Rock is a popular form of music that has evolved over the past couple of decades starting in the 1950s until present day. Rock music has been known to be used as a form of expression over the years. Despite its sometimes negative and defiant lyrics, rock is a form of art that allows one to release his/her feelings through singing in an expressive tone. Later styles of heavy rock music in the 1990s, such as grunge, the typical example being Seattle's Nirvana, show influences of heavy metal but are typically not labelled sub-genres of heavy metal, as opposed to thrash metal and glam metal. The general absence of virtuosic guitar solos is perhaps one reason grunge bands haven't been considered heavy metal bands. Another key artist during this time was Megadeth, which combined the relentless, speedy thrash metal riffs with the fancy guitar soloing of speed metal like Judas Priest. Rock-n-Roll has never just been music. Heavy metal, Rhythm & Blues, Art Rock, New Wave, and the rest may be primary styles or genres but as sub-categories of rock, or rockin’ roll they do not cumulatively add up to the whole. Rock n’ Roll is a movement, a lifestyle, in many ways a belief system and all that Rock n Roll is today it owes to history: two years, no more than three when the fabric of American popular culture was torn apart and rewoven, and a new era explosively began. Rock n Roll started with slavery. To understand we must...

...my exchange student peers. It is one of the most interesting places, where it is historically related to the First Nation People. Therefore, I would like to write this essay paper about the Writing-on-Stone Park. Became a provincial park in January 1957, Writing-on-Stone Park is set in Southern Alberta and extremely rich in histories, stories and dreams. (Barry, 2011) It contains one of the most important collections of ancient rock art found anywhere in North America. It is a sacred landscape to First Nation. Some part of this is located near the Milk River where there is some evidence that native people were inhabited here long time ago. Once getting through in the park, it is clearly seen that there are many figured stones surrounded the park. In addition to recreation during the nice weather, it is the place where the histories of First Nation tribes can be told. For example, some people believe that the rocks are created by spirits, while some people believe that the rocks could help us to discover the future. It is probably also the place where native tribes such as Blackfoot are likely to create rock craving and painting or the Rock Art. These rock cravings are kind of the message to convey and imply what was happened in the past by those First Nation people. Sacred...

...When Rock arrived on the music charts in the 1950's, a merging of African-American and White music, it made a huge impact on society. As a general rule I am not heavily into music, but I was drawn to Rock for some inexplicable reason. It is just the music I like. This genre will be difficult to write about because the origin of Rock is unclear; there are traces of Rock's style back into the 19th Century. It is also a very broad subject and I will have to compress a lot of information into as few pages as possible. Be that as it may, Rock is, in my opinion the best music genre on the charts. There is so much information on Rock that I will have to have questions I want to find the answers to about the music. My first question will be, "What instruments are commonly used in a rock band?" This will not be hard to answer as it is a very easy question that has a definite answer. The next question will be, "Who were the first artists to produce Rock music?" This is also an easy question were I will discuss the first Rockers. Continuing on, my next question will ask, "How was the term Rock and Roll' created, and by who?" This may turn out to be a hard question to answer because I am sure there a multiple answers. "Has Rock become more or less popular since its inception?" will be my next question. For this question I will have to look for a survey or poll of some type and present its data. My final question will be, "How has the Music been changed over the years and who changed...

...LITTLE ROCK NINE The Little Rock Nine: The Crisis That Shaped a Nation Angela Manjarrez Point Loma Nazarene University Abstract The Little Rock Nine were nine African American students from Little Rock, Arkansas who enrolled at Central High School. No African American student was allowed to enroll in an all White school, until the Supreme Court passed a ruling in which schools would be integrated. It was a trying time for these nine students as they suffered through violence, hate, segregation, humiliation, and fear. Little did they know that their actions during the 1957-1958 school year would mark an important event that changed history forever. They endured massive amounts of pain during their ordeal of mainly trying to get an education. But they received help and support along the way. The Little Rock Nine shaped the educational systems and gave hope to a divided nation at the time. They would grow to be successful individuals and remembered as unsung heroes in Civil Rights history. The Little Rock Nine: The Crisis That Shaped a Nation In 1957, nine ordinary teenagers walked out of their homes and stepped up to the front lines in the battle for civil rights. The “Little Rock Nine” or the “Little Rock Crisis” refers to a time in history in which nine African American students were prevented from attending Little Rock Central High School, located in the southern state of Arkansas. This also took place during the Civil Rights Movement. The Little Rock Nine were...
