  1. 2. resources- such as solar and wind power and water are unlimited in supply.
  2. 5. Niña -is a weather pattern that occurs in the Pacific Ocean. In this pattern, strong winds blow warm water at the ocean's surface from South America to Indonesia. As the warm water moves west, cold water from the deep rises to the surface near the coast of South America
  3. 7. resources -is a substance that is being used up more quickly than it can replace itself. Its supply is finite. Most fossil fuels, minerals, and metal ores are nonrenewable resources.
  4. 8. the process of individuals moving into a range from elsewhere
  5. 9. of the almost spherical concentric regions of matter that make up the earth and its atmosphere, as the lithosphere and hydrosphere.
  6. 12. act of leaving one's own country to settle permanently in another; moving abroad.
  7. 15. envelope of gases surrounding the earth or another planet.
  8. 18. a substance or object) capable of being decomposed by bacteria or other living organisms.
  9. 20. rate- which measures the average number of children per woman. The global average fertility rate is just below 2.5 children per woman today. Over the last 50 years the global fertility rate has halved.
  10. 22. capacity-the number of people, other living organisms, or crops that a region can support without environmental degradation.
  11. 23. (O3) is a highly reactive gas composed of three oxygen atoms.
  12. 24. -fog or haze combined with smoke and other atmospheric pollutants.

  1. 1. rate-the ratio of deaths to the population of a particular area or during a particular period of time, usually calculated as the number of deaths per one thousand people per year.
  2. 3. growth-growth whose rate becomes ever more rapid in proportion to the growing total number or size.
  3. 4. means the usual condition of the temperature, humidity, atmospheric pressure, wind, rainfall, and other meteorological elements in an area of the Earth's surface for a long time. In simple terms climate is the average condition for about thirty years.
  4. 6. process of making an area more urban.
  5. 10. Nino-an irregularly occurring and complex series of climatic changes affecting the equatorial Pacific region and beyond every few years, characterized by the appearance of unusually warm, nutrient-poor water off northern Peru and Ecuador, typically in late December.
  6. 11. regions of the surface, atmosphere, and hydrosphere of the earth (or analogous parts of other planets) occupied by living organisms.
  7. 13. density- is the number of people per unit of area, usually quoted per square kilometre or square mile, and which may include or exclude for example areas of water or glaciers. Commonly this may be calculated for a county, city, country, another territory or the entire world.
  8. 14. population growth-the maintenance of a population at a constant level by limiting the number of live births to only what is needed to replace the existing population.
  9. 16. warming-a gradual increase in the overall temperature of the earth's atmosphere generally attributed to the greenhouse effect caused by increased levels of carbon dioxide, chlorofluorocarbons, and other pollutants.
  10. 17. natural event-A natural disaster is a major adverse event resulting from natural processes of the Earth; examples are floods, hurricanes, tornadoes, volcanic eruptions, earthquakes, tsunamis, storms, and other geologic processes.
  11. 18. number of live births per thousand of population per year.
  12. 19. factor-the environmental factor that is of predominant importance in restricting the size of a population lack of winter browse is a limiting factor for many deer herds.
  13. 21. growth- takes place when a population's per capita growth rate decreases as population size approaches a maximum imposed by limited resources, the carrying capacity( K).
