Q

What are 3 characteristics of natural resources?

A

CULTURAL VALUE - influence people’s decision that a commodity is desirable and acceptable to us (EX: North Americans want to drive private automobiles rather than use public transportation)

LEVEL OF TECHNOLOGY- must be high enough to use the resource.
(EX: Petroleum is the preferred fuel in private automobiles because autos are easily powered by gasoline engines.)

APPROPRIATE ECONOMIC SYSTEM - affects whether a resource is affordable and accessible. (EX: North Americans are willing to pay high enough prices for gasoline to justify removing petroleum from beneath the seafloor and importing it from distant places)

Examples - oil in Saudi Arabia
Lithium in Bolivia
Ski resorts in the mountains

Q

provide an example of shifting cultural values.

A

A swamp is an example of how shifting cultural values can turn an unused feature into a resource. A century ago, swamps were seen in the United States as noxious, humid, buggy places where diseases thrived instead of places that provided usable commodities. Swamps were valued only as places to dump waste or to convert into agricultural land. Eliminating swamps was good because it removed the breeding ground for mosquitoes while simultaneously creating productive and valuable land.

Q

what is a renewable resource?

A

Something produced by nature at rates similar to those at which it is consumed by humans

EX: biomass, sun, water, and wind

Q

what is a non-renewable resource?

A

A resource that is either not being produced by nature or is produced much more slowly than it is used by humans

fossil fuels (oil, natural gas, coal)
uneven distribution
Depletion
Nuclear energy

Q

What is resource management?

A

managing the supply and consumption of resources -

Resource management is exceedingly complex because each resource varies geographically and physically. Resources also vary in value, depending on human factors: culture, technology, beliefs, politics, economics, and government style. Many resources are publicly controlled, so resource management is a political process.

Q

What is OPEC?

A

Organization of the Petroleum Exporting Countries

It is an organization enabling the co-operation of leading oil-producing countries in order to collectively influence the global oil market and maximize profit.

Q

What is nuclear energy?

A

the energy released during nuclear fission or fusion, especially when used to generate electricity.

Nuclear power is an important source of electricity in several states. Many sites have more than one reactor.

Q

What is fusion?

A

the process or result of joining two or more things together to form a single entity. (joining two atoms together)

Most peaceful generation of nuclear power today relies on fission (splitting atoms) of uranium, although plutonium also can be used.

Q

Why smart phones are an interesting example of the relationship between natural resources and human societies and the consequences of their production and use for both?

A

Indium responds when contacted by another electrical conductor

Smartphones require a diverse array of materials, including rare earth metals (such as neodymium, dysprosium, and tantalum), lithium, cobalt, and aluminum. These materials are mined from the Earth’s crust, often in environmentally sensitive areas.

The production process consumes significant energy, from mining to manufacturing. For instance, the energy used in smartphone production since their commercial release is substantial

Q

What are the main energy resources used in less-economically developed countries?

A

At low levels of income and economic development, economies rely predominantly on traditional biomass, such as fuelwood, charcoal, dung, and agricultural or household waste, for cooking and space heating, and on human power for productive agricultural and industrial activities.

Q

What are the main energy resources used in more-economically developed countries?

A

Relatively wealthy developed countries possess more than 60% of the world’s COAL and more than 60% of NATURAL GAS. China is the leading producer of coal, but the United States is also a major coal producer and user. Russia is the leading producer of natural gas. Other than China and India, which have significant coal deposits, most countries in Africa, Asia, and Latin America have few reserves of coal or natural gas.

Because relatively rich developed countries consume more energy than they produce, they must import energy, especially oil, from developing countries. The United States imports about 45% of its needs, Western European countries more than 50%, and Japan more than 90%.

17
Q

How are oil and coal formed?

A

Both coal and oil are fossil fuels. That means they’re formed from organic matter – stuff that was alive on Earth millions of years ago – that was covered by heavy layers of rock. Over time, the increased pressures and heat resulting from the overlying rock transformed the decomposed matter to coal or oil.

18
Q

Why does oil and coal contain energy?

A

Coal is a black or brownish-black sedimentary rock that can be burned for fuel and used to generate electricity. It is composed mostly of carbon and hydrocarbons, which contain energy that can be released through combustion (burning).

19
Q

Why is oil and coal so unevenly distributed?

A

Natural resources such as oil, coal, and natural gas, are not distributed evenly around the Earth as their deposits depend upon climate and organisms that lived in that region, and the geological processes that have occurred millions of years ago.

20
Q

What are the factors that drive the market value of natural resources?

A

supply and demand
Substitutability - the ability to substitute a resource for a different one.
Renewability - the ability to continue to make the resource

21
Q

What is fracking?

A

Fracking creates fissures in rocks underground that allow the gas to be extracted.

One of the most significant recent developments in the fossil fuel industry has been the rapid growth of natural gas and oil production in the United States, made possible by the application of hydrofracturing, or “fracking” technology. This has opened up vast deposits of gas and oil that were formerly unavailable because the gas is located in rocks through which it does not easily flow, and thus cannot be extracted using simple wells.
