Concept from Weekend Reading

Concept from Reading C.1-C.5

By Kelly Moran

In the weekend reading I learned a lot about metal resources, it's uses, the layers of the earth, and the composition of materials. First of, the quantity of each metal produced varies. For example, nearly 100 times more aluminum is produced worldwide than tin. China holds the greatest mass in Table 1.4 of all the substances mentioned. I also learned about the three layers of the earth which are the Atmosphere, Hydrosphere, and Lithosphere. The atmosphere provides us with nitrogen and oxygen minerals. The Hydrosphere provides us with water and dissolved minerals. Lastly, the lithosphere, which is made  up of a crust, a mantle, and core, is the solid part of the earth that provides us with greatest variety of chemical resources with which almost all our everyday products are made from. An ore is a naturally occurring rock that can be mined and often contains minerals in it that are very valuable. Occurring collections of ores in the lithosphere are called deposits. The components in ore deposits consist of minerals. The United States has had an advantage in terms of mineral resources because we have so many mines and outlets to find minerals. But in recent years, the United States had decided to import most of it's mineral resources. In mineral resources you must decide the importance of it and wisest use for it. For example, the quantity of the ore, percent of metal in the ore, type of mining needed to extract, and much more. Before old mines we not valuable for mineral resources because it was to difficult to extract the little amount of minerals from the ore but now new technology has come out to extract the 1 percent of Iron from an ore easily. The percent by mass of each component found in a sample is called its mineral composition. These are the important concepts from the weekend reading.
