Mineral Physical Properties Essay Example for Free

Mineral Physical Properties Essay A mineral refers to an inorganic element or compound that is naturally occurring in a solid state and has a specific chemical composition and a regular, internal crystalline structure. A mineral has a highly ordered structure and particular physical properties. Some of the varying physical characteristics of mineral include color, lustre and habit. Color is the first physical property of minerals that varies between same mineral. Color is an apparent aspect in minerals but it proves unreliable in identifying minerals. It occurs due to the minerals light absorbing and reflecting properties. The variability of color between the samples of the same mineral exists because color mainly comes about as a result of electronic alterations. For instance, quartz is found in different colors such as black, white, purple, pink, blue or clear. It is observable that completely varying materials may have the similar color. Secondly, lustre is a mineral physical property that varies among the same mineral. This refers to the amount of light that it reflects from its surface. A mineral may appear differently depending on the quality, intensity or quantity of light that it reflects. The mineral for instance may appear metallic or sub metallic or may appear splendent, shining or dull. Finally, the habit is another varying physical property. It refers to the crystal’s shape of the mineral. The habit is usually shaped by the conditions under which the metal grew. It is common for a mineral to have many varying habits. The habit of a mineral may be described as the habit of crystals or the habit of crystal aggregates (Ernest, 1995). Conclusion Mineral physical property can be relied on during identification of mineral. However, certain physical properties show a range of characteristics making them less reliable in the identification process. Reference Ernest, Nickel. (1995).

I Beat the Odds :: Personal Narrative Writing

I Beat the Odds Often times I ask myself if the education that I have received was ever worthwhile. I have always received a public-school education. As a matter of fact, I went to a junior high school and high school which was close to the university I am currently attending: the University of Southern California (USC). Growing up, the University of Southern California seemed like an impossible dream. The education I received was insufficient to prepare me for the standardized tests given to high school students across the nation. Preparation for higher education is deficient; mandatory information about college is not given to students. However, receiving an inferior education from a public school strengthened my character and enhanced my perseverance to do great things. My passion and determination brought me to the realization that I can accomplish anything. I was fortunate to grow up in an environment where education was upheld a great value. I understood that the only key to success was to go through the narrow gate that people rarely are willing to enter because they do not take advantage of its offer. Attending the University of Southern California gave me the opportunity to mentor under privileged students about education through an on-campus program called the Joint Educational Program (JEP). I believe education is interlinked with educating others, not solely on subjects such as science, math, or English, but by passing on the information of the prominence of education. I feel compelled to pass down the torch to the unfortunate who do not comprehend the ability that one will gain after receiving education. The atmosphere of my university is not at all the way I expected it to be while I was in high school. At USC, the education is fantastic! I have never learned so many things in such a short period of time. I probably learned more things in one semester than most of my years in high school. I am in the pre-medical field. The classes that the university is making me take are overwhelming. I had doubts of my capability to continue with the field, but when I compare myself with my classmates I feel that I study more than they do, and am retaining a lot more information than they are, because they have already learned
