They are all renewable resources.
They are all nonrenewable resources.
They are all natural resources.
They are all resources that come from living organisms.


2. Which of the following is not a natural resource?
aluminum
water
synthetic diamonds
coal

4. Which of the following is an example of a nonrenewable resource?
coal deposit
soil
wind
hydroelectric power


7. Why are fossil fuels considered nonrenewable resources?
It takes 500 million years for reserves to form.
Burning fossil fuels pollutes the atmosphere.
They are being consumed in many different ways.
They need to be extracted from the ground.


8. Burning fossil fuels releases which of the following into the atmosphere?
carbon
carbon dioxide
oxygen
heat


9. Use of fossil fuels contributes to which of the following?
only water pollution
air pollution, water pollution, and global warming
only air pollution
only global warming


10. What is a strategic mineral?
a nonmetallic resource
one that is exported from the United States
one that is easily removed from the ground
one that must be imported to the United States


11. Which of the following is a good reason to extract mineral resources from the earth?
It depletes the supply.
It can contaminate water supplies.
It increases surface runoff.
It makes the resource available for use.


12. Which of the following is a reason not to extract mineral resources from the ground?
It can cause air, soil, or water pollution.
It can provide new jobs.
It can improve technology.
It can allow the resource to be used in a helpful way.


13. Which type of mine may be used to remove coal from a coal seam deep underground?
openpit mine
strip mine
subsurface mine
none of the above


18. Copper ores are abundant in the world. Why is copper considered a nonrenewable resource?




19. Identify strategic minerals, explain their importance, and locate where they are found.

1 - They are all natural resources.
2. - synthetic diamonds
4 - soil
7 - It takes 500 million years for reserves to form
8 - carbon dioxide
9 - air pollution, water pollution, and global warming
10 - one that must be imported to the United States
11 - It makes the resource available for use.
12 - It can cause air, soil, or water pollution.
13 - The most common type of underground mine is the shaft mine. Used to reach coal seams which are too deep for surface mining
18 - copper cannot be replaced after mining
19 - Tantalite is a black, heavy mineral not prized by collectors and little known outside high-technology circles.
Tantalite is the most widespread tantalum mineral and makes for an important ore for the industrially useful metal. Tantalum is used in alloys for strength and higher melting points, in glass to increase the index of refraction, and in surgical steel, as it is non-reactive and non-irritating to body tissues.
Tantalite is the principal ore of tantalum. It is found chiefly in granite pegmatites and as a detrital mineral, in some places in important amounts, having weathered from such rocks. The chief producing areas are the Congo and Nigeria
