1. World Resources Capital Resources : the money and machines used to produce goods and services

2. World Resources Human Resources: the people who perform various tasks

3. World Resources Natural Resources: materials that people take from the natural environment to survive and satisfy needs

4. 3 Types of Natural Resources Renewable – the environment continues to supply or replace them –S–Soil is always being replaced by weathering rocks and decomposition of living material –W–Water cycle (hydrologic cycle) returns water in the form of rain or snow

5. Natural Resources Non-renewable: cannot be replaced once they have been used –Fossil fuels – coal, oil, natural gas –Other minerals include iron, copper, aluminum, uranium, gold

6. Inexhaustible Resources Solar or planetary processes that are unlimited in quantity Sunlight, geothermal heat, winds, tides

7. Resources Main energy source today: non-renewable fossil fuels At present rate of consumption, oil reserves will be tapped in less than a century There is enough coal left for 200 years, but: –Causes air pollution, like acid rain

8. Nuclear Energy Produced by fission (splitting uranium atoms) Possible Drawbacks: leaks, explosions, radioactive waste

9. Geothermal Energy Energy from the earth’s internal heat in volcanic areas; magma heats underground, which produces steam that can be used as heat or electricity Iceland, New Zealand, Japan, Italy

10. Solar Energy Energy produced by the sun. Although difficult, solar radiation is potentially the greatest source of inexhaustible energy

11. Other energy sources Wind Power Tides Vegetable Oil Sugarcane

12. Resources are not distributed evenly throughout the world; therefore, countries have to interact with each other. Imports – resources brought into a nation Exports – resources shipped out of a nation

13. World Economic Activity Economic Activities: the way people make their living Primary Activities – activities that use natural resources directly

14. Secondary Activities Activities that process raw materials Manufacturing: turning raw materials into finished products

15. Tertiary Activities Activities that provide a professional service Transportation, law, journalism, health care, sales, banking, etc.

16. Quaternary Activities Activities that provide information, management, or research by highly trained people
