3. Chapter 4, Section 1
World Resources
• How do renewable resources and
nonrenewable resources differ?
• What energy sources are available to
individuals and nations?
4. Chapter 4, Section 1
Natural Resources
• Natural resources are materials in the natural environment
that people value and use to satisfy their needs.
• Renewable resources are natural resources that are
constantly being replaced or regenerated by the
environment.
• Soil and fresh water are constantly being replenished by
natural processes.
• Nonrenewable resources are resources that cannot be
replaced once they have been used.
• Nonrenewable resources are minerals that formed within
the earth’s crust over millions of years.
• Coal, oil, and natural gas are nonrenewable fossil fuels
that formed from the remains of ancient plants and
animals.
• Recycling and reduction of consumption are ways of
stretching limited supplies of nonrenewable resources.
5. Chapter 4, Section 1
Energy Sources
• Modern industrial countries use energy to light cities,
power vehicles, and run machines.
• Fossil fuels are the most important and heavily used
source of energy, but oil and natural gas reserves are
spread unevenly across the world and will not last forever.
• Nuclear energy is produced by fission, the splitting of
uranium atoms in a nuclear reactor to release their stored
energy, but many concerns surround the use of nuclear
power.
• Water power uses the energy of falling water to generate
electricity.
• Geothermal energy uses the energy that comes from the
earth’s internal heat to produce steam to heat homes or
make electricity.
• Solar energy is energy produced by the sun that is stored
to heat water and homes and to generate electricity.

World Economic Activity
• What are four different categories of
economic activities?
• Why are global trade patterns changing
today?
• What kinds of data indicate a country’s
level of development?
9. Chapter 4, Section 2
Economic Activities
• Primary economic activities are those that rely directly upon
natural resources, of which hunting, gathering, herding,
forestry, farming, and mining are examples.
• Subsistence farming is the practice of only growing enough to
feed one’s family or village, and commercial farming is the
practice of raising crops and livestock to sell on the market.
• Secondary economic activities are those in which raw
materials are used to manufacture products of greater value.
• A cottage industry is a small-scale industry practiced in
subsistence economies, while commercial industry turns out
large quantities of manufactured goods.
• Tertiary economic activities are service industries, which
involve firefighters, lawyers, and salespersons.
• Quaternary economic activities are jobs that focus on the
acquisition, processing, and sharing of information, such as
education and government.
10. Chapter 4, Section 2
Global Trade Patterns
• Nations set up trade networks when they do not have
all the resources and goods they want.
• Goods that are sent out of a country are called exports,
and goods that are brought into a country are imports.
• Governments seek a favorable balance of imports and
exports because too many imports can be damaging to
a nation’s economy by increasing unemployment and
the nation’s debt.
• Trade routes are determined by geography,
transportation technology, and international relations.
• Modern technology is changing the nature of global
trade, as computer and satellite networks allow
business deals and payment transactions to be
conducted electronically.
11. Chapter 4, Section 2
Level of Development
• Economic activities and trade patterns affect a
country’s level of development.
• Modern industrial societies are considered to be
developed, countries with lower levels of prosperity are
considered to be underdeveloped, and nations showing
evidence of progress are called developing countries.
• The wealth of countries can be compared by looking at
the per capita gross domestic product (GDP).
• Developed countries enjoy a higher standard of living
compared to developing and undeveloped countries.
• Developed countries have higher levels of education
and health care, and they have more transportation and
communication facilities per person.
• People in developed countries consume more food and
live longer than people in poorer countries.
