Review chapter 13

1. Global warming leads to

Rising sea level, increased droughts, increased storms.

2. CO2 has been measured in Hawaii since 1958 shows steady increase.

3. CO2 reduced by oceans, phytoplankton, and tropical rain forests

4. Although CFCs reduced, still a treat because they persist and destroy ozone for decades.

5. Ozone hole appears over poles because they have stratospheric clouds where Cl2 is captured.

6. Ozone protects by blocking UV light from the sun.

7. Seasonal changes occur because of earths tilt on axis of 23.5 degrees in relation to sun.

8. Elevation changes climate because, temperature falls as elevation increases.

9. As cold air sinks, it compresses and warms.

10. Weather is the atmospheric conditions on a specific day.

11. Surface ocean currents caused by wind and influenced by earths rotation.

12. La Nina has cooler water in eastern Pacific ocean.

13. Greenhouse effect, atmosphere traps heat radiated up from earths surface.

14. DNA damage caused by high UV radiation at earth’s surface.

15. Montreal protocol, established international limits on CFC production to protect the ozone layer.

16. El Nino, wind push warm water eastward in the pacific ocean.

17. CO2, greenhouse gas released into atmosphere when fossil fuels are burned.

18. Prevailing winds, trade winds, westerlies, polar easterlies.

19. Equatorial regions, have vertical sunlight, direct and strong sunlight.

20. Ozone molecules are destroyed by chlorine atoms that come from CFCs

21. Latitude –

22. Kyoto protocol –

23. Warm air can hold more water vapor than cold air

24. It takes 10-20 years for CFCs to reach the stratosphere.

25. Why is surface level ozone production a problem and not a solution to ozone destruction in the stratosphere?

26. Why is protecting the rain forest important to protecting the world from global warming?
