Editor's Notes
- Figure 14.1 Cell phone use while driving
- Figure 14.2 The greenhouse effect The normal greenhouse effect warms Earth to a hospitable temperature. An increase in greenhouse gases intensifies the greenhouse effect, trapping more heat and raising Earth’s temperature
- Figure 14.3 Greening your space
- Figure 14.4 Louder and louder The human ear perceives a 10-decibel increase as a doubling of loudness. Thus, the 100 decibels of a subway train sound much more than twice as loud as the 50 decibels of a rushing stream. *Note: The maximum exposure allowed on the job by federal law, in hours per day: 90 decibels, 8 hours; 100 decibels, 2 hours; 110 decibels, ½ hour.
