Glg 101 Week 1 Review Essay

By completing the interest survey, I felt in the position of a student: to have to think on unusual things and understand that they are part of who I am. I realized that I could know a bit more about me. I learned about my favorite food and my favorite singer, which are different from 10 years ago.

Each natural stone has its own unique color, veining and natural characteristics such as: porosity and hardiness.

Quartz is the most abundant single mineral on earth. It makes up about 12% of the earth's crust, occurring in a wide variety of igneous, metamorphic and sedimentary rocks.Quartz varieties are commonly separated into two groups based on the size of the individual grains or crystals. Macrocrystalline quartz in which individual crystals are distinguishable with the naked eye, and cryptocrystalline quartz in which the individual crystals are too small to be easily distinguishable under the light microscope. Some of the verities of the Macrocrystalline quartz are

Layer 6: Presentation - Layer 6 takes the data provided by the Application layer and converts it into a standard format that the other layers can understand.

Amethyst is purple quartz; the color is caused by iron (Fe4+) impurities. Azurite is a copper mineral. Calcite is a very common and widespread mineral and has highly variable forms and colors. Lodestone is a natural magnet. Mica is a sheet silicate. Rose quartz is translucent and a variety of the silica mineral quartz, found in pegmatite. Talc almost always found in foliated masses in metamorphic rocks with many carbonate minerals. Pyrite is a very common mineral. The brassy-yellow metallic color of pyrite has lead people to mistaking it for Gold, so its common nickname is

2. Use the geologic definition of a mineral to determine which of the items listed in Figure 1.1 (p.3 lab book) are minerals and which are not minerals. Put an “X” in the appropriate box.

3. The six major minerals are calcium, phosphorus, magnesium, sodium, potassium, and chlorine. The rest are trace minerals, which are not less important, but you just need them in less amounts.

In the following space, explain the role of fossils in developing the Geologic column. Your explanation must be between 200 and 300 words.

* Diamond is the strongest natural mineral known by a man. It is a crystalline form of carbon.

Around the world our water supply is depleting. Our water is becoming contaminated making it harmful for both mammals and aquatic life. Today over one billion people go without adequate water supply and every fifteen seconds a child dies of waterborne illness. Sources of water that once supplied water to millions can no longer meet the supply and demand of the water need. Scientist predict that the amount of useful water will keep depleting greatly in the years to come. In the next couple of pages it will talk about both the geological and human reasons as to why are water supply is depleting.

These planets evolved so differently, because of their space from the sun. Making Venus hotter than earth and causing changes to the

Using the assigned readings for Week Six, prepare a 50- to 75-word response to each of the following questions.

Minerals are naturally occurring, inorganic, solid, crystalline substances which have a fixed structure and chemical composition. Minerals are an important part of Geology, especially when studying Crystal and mineral growth. Understanding how crystals grow and the difference between slow and fast cooling rates is also important in Geology. Knowing the difference between cooling rates is important because cooling rate changes the texture of rocks and minerals. The purpose for the Crystal Growth experiment is to identify which Solubility and temperature produces larger crystals, and to simulate natural crystal growth. We will achieve the results we desire by conducting the experiment thoroughly and correctly, as well as correctly

Venus has a very thick atmosphere a hundred times thicker than earth's. It is made up of almost entirely carbon dioxide. The atmosphere is protected with a very thick cloud cover, much of it is sulfur dioxide clouds. Earth's atmosphere is unique and made up of mainly nitrogen and oxygen. The reason that we have so much of those two gases and pick up oxygen is actually due to life on earth. Also, it is the only planet that has an ozone layer that blocks harmful UV radiation. Mars does have an atmosphere, although it's close to a hundred times thinner than earth's. In the case of mars it's so thin that there is not really much going on. There are occasional dust storms, it actually engulfs the entire planet. One other very important difference

Mars and Venus are both known to have nitrogen in their atmospheres. When you compare the amount of nitrogen between Venus, Earth, and Mars you will notice that Earth does contain more nitrogen than the neighboring planets. Because the atmosphere on Venus is so thick, it does make the total nitrogen content much higher than Earths. The nitrogen molecules that are found are most likely the source of meteorites. There are multiple differences that can be found between the atmospheres between Venus and Mars. One prime example is that while Venus has a thick, hot and dry atmosphere, Mars is thinner and much colder. Mars has about 10,000 times less the amount of carbon dioxide in its atmosphere as opposed to Venus. Mars is often referred to as the
