Unit 1 Sec. C Summary HW

6/29/14

1) Atmosphere: nitrogen and oxygen

Hydrosphere: water and dissolved minerals

Lithosphere: petroleum and metal bearing ores

2) a. The three major parts of the lithosphere are the crust, mantle, and core. The crust contains silicates, natural gas, coal, oil, and others. The mantle contains silicates of magnesium and iron. The core contains iron and nitrogen. 

b. The crust

3) a. Peru

b. Chile

c. China

4) China

5) Minerals are naturally occurring solid compounds containing the element of interest and the ore is a rock or mineral that can be mined and you can extract metals or other materials from it.

6) The factors that make it feasible of mining a particular metallic ore at a certain cite are considering the quantity of useful ore, the type of mining and processing needed to remove the metal, how far away it is from the metal refining facilities, and the environmental impact.  

7) The workers needed to see if the mine has useful ore to be reopened and the environmental impact.

8) “Useful ore” means when the mine has metals in good conditions and there is plenty that can be used.

9) Active metals are conductive making it more difficult to process and refine than less active metals.

10) Copper would be the easiest to process because it is less reactive than zinc and magnesium.
