c) Indicate how erosion can be reduced.

6 Identify ten key minerals  and indicate a function or use of each.

a) Indicate how long the supplies, of your selected minerals, will last for the world, and the U.S..

b) What is this mineral commonly used for?

Select the element, then go to Mineral Commodity Summaries", select the most recent year.

7. Define the terms reduce, reuse, recycle, and refuse and indicate how they could be applied to your life.  (refuse, as in - I refuse to use that product)

8. Define hazardous and non-hazardous wastes.

a) Name the principal types, sources, and effects of each?

b) How can they be managed, and reduced?

9. Describe the rock cycle:

a) Insert a picture of the rock cycle and explain how rock cycle recycles the earth's materials. When describing the rock cycle make

    sure you indicate how a rock can be converted to each of the rock types (igneous, sedimentary, and metamorphic).

b) Provide two examples of  igneous, sedimentary, and metamorphic rocks.

10. Finding Mineral Resources:

a) How mineral resources found and extracted from the Earth's crust?

b) What is economic depletion of a mineral resource?

c) Describe strip mining. Describe the method and its short and long term environmental impacts and possible solutions.

d) Describe subsurface mining. Describe the method and its short and long term environmental impacts and possible solutions.

e) Will there be enough nonrenewable mineral resources for future generations?
