Concept:  Capital Resources

Definition:  Capital Resources are goods produced and used to make other goods or services.  Common examples are tools, machinery, equipment, and buildings.

Comprehensive Questions:

What capital resources are used to mine coal underground?  (See pictures on pgs. 6-7.)
Many examples!  Elevator, ventilation shaft, ore cage, front-end loader, mine cart, drilling machine, crusher, etc.

The story talks about mining coal. Is coal a capital resource?
No, coal is a natural resource.

What capital resources are used to mine coal on the surface? (pgs. 16-17)
Dragline excavator, conveyor belt, front-end loader, dump truck

When drilling for oil, what is an unsuccessful well called?
Duster

Why do entrepreneurs and mining companies drill for oil if nine out of ten wells are dry “dusters?”
The one successful well may really pay off!  Of course, it may not.  There is risk to all oil exploration and, indeed, to all investment.

What is the name of a person (human resources) who looks for oil?
Geologist

A mining drill is a capital resource. What special kind of drill is used to drill for oil?
A rotary steel drill studded with industrial diamonds

When geologists look for oil, what other natural resource do they frequently find?
Natural gas

How is oil transported?
Pipeline, tanker truck, rail tanker, ocean tanker

Does mining pollute the environment? How?
Yes – water gets polluted, toxic smoke can go into the air, oil spills can harm wildlife and water.  All forms of production cause some pollution.  The good news is that humans can help control the effects of pollution.  For example, in the United States the air and water are cleaner now than they were 30 years ago.  As individuals we can practice the four R’s:  reduce, reuse, recycle, and refuse.

How do coal mining companies help the environment after they mine for coal?
They reclaim the land that is mined.  Top soil is put back and grass and trees planted.  Mining wastes are put back under the ground. This is much better than in years past when ugly piles of waste were left and the land went totally un-reclaimed.
