Unit 8: Human Environment Interaction

Most sources of energy today are

• fossil fuels

• wind powered

• from the developed world

• reneweable

Which group consumes one-fifth of the world's energy, while only making up one-twentieth of Earth's population?e\

• Chinese

• Americans

• Indians

• Europeans

Prior to the Industrial Revolution, humans relied mostly on what kind of power?

• proven

• nonrenewable

• animate power

• inanimate power

Fossil fuels are

• finite resources.

• unevenly distributed around the world.

• plants and animals buried millions of years ago.

• both finite resources and buried plants and animals.

• All the above

The global energy issue derives in part from the fact that fossil fuels

• are renewable energy sources.

• are distributed uniformly across Earth.

• have an infinite supply.

• were formed in the distant past

Saudi Arabia has relatively large proven reserves of

• petroleum

• coal

• natural gas

The United States has relatively large proven reserves of

• natural gas

• coal

• petroleum

• tar sandstone

At current rates of use, the proven reserve to run out first would be

• coal

• petroleum

• natural gas

• hydroelectric power

Pollution occurs if

• there is more waste that resources can tolerate.

• there is less waste than environmental capacity.

• recycling occurs.

• waste is thrown away.

Air pollution is

• a form of photochemical smog.

• gaseous sulfur and phosphorus.

• a concentration of a trace substance at a level greater than occurs in average air.

• concentrated in tropical regions.
