Earth Science Powerpoint presentation for Rock and minerals

1. Ear th Sc ience

2. Objectives Describe how ore minerals are found, mined, and processed for human use Demonstrate how fossil fuels are formed Appreciate the importance of minerals in our daily lives

3. Salt a mineral from halite, is one of the essential minerals that we always use at home. It makes food tastier and brings out the flavor of what you are eating.

4. Home and Personal Use

5. Aside from salt, other minerals compose some of the items and equipment found in our houses Feldspar is a component for ceramics, glassware, and pottery. It is also an ingredient in making soaps

6. Gold, silver, and platinum are made into pieces of jewelry and other important articles at home.

7. Quartz is used to produce glass and fiberglass usually used at home.

8. Electronics, Infrastructure, and Manufacturing

9. Electronics, Infrastructure, and Manufacturing Copper serves as an important material in electronics and wiring because of its conductive properties.

10. Silver is utilized in electronics for the same reason.

11. Silica is a mineral that contains silicon, a metalloid that has some properties of metals such as the ability to conduct electricity. Foodstuffs such as seeds, spices, herbs and even pet food can be kept fresh when stored with silica gel packets. Not only do they prevent food from becoming stale, but they also act as a barrier against mould and mildew growth.

12. Tungsten and molybdenum are used widely for the filament in incandescent bulbs because of their high melting points. Tungsten Most molybdenum is used  to make alloys . It is used in steel alloys to increase strength, hardness, electrical conductivity and resistance to corrosion and wear.

13. Graphite , known in your pencil "lead”, can also be used in manufacturing.

14. Economics Mining of minerals contribute to the gross domestic product (GDP) of a country. Gold is used as a reserve and serves as a backup for currencies. The amount of reserves of gold correlates to inflation. If the central bank of a country buys gold, the country’s currency is affected because of the fluctuations in the supply and demand of the currency

15. Mined materials are needed to construct roads and hospitals, to build automobiles and houses, to make computers and satellites, to generate electricity, and to provide the many other goods and services that consumers enjoy. mining is economically important to producing regions and countries .

16. Minerals are naturally occurring, inorganic solids with a definite chemical composition and a crystal lattice structure. Although thousands of minerals on earth have been identified, just ten minerals make up most of the volume of the earth’s crust–plagioclase, quartz, orthoclase, amphibole, pyroxene, olivine, calcite, biotite, garnet, and clay
