1Global Population

1. Describe the regions of the globe that have the greatest population density (more than 500 people per square mile). Use the world political map on page 8 of the webquest for reference. 2. Describe the regions of the globe that have the lowest population density (less than 1 person per square mile). 3. Compared to the rest of the world, would you categorize Minnesota's and the Midwest area's population density as HIGH, MEDIUM, or LOW?

2Prevailing Winds

4. Look at the map that shows the wind directions of the globe. The purple arrows show the most common wind directions in various regions in the world. Describe the pattern that the winds seem to take globally. 5. Which direction to the prevailing winds move in Minnesota?

3Acid Rain

6. Acid rain is a more "localized" problem than global warming in that emissions from a given area usually precipitate within several hundred miles of their source. Therefore, local prevailing winds are important. What regions of the world have a severe acid rain problem? 7. Some areas of the globe are more sensitive to acid rain. That is because the soil does not have natural pH buffers to equalize the acidity. Pick two areas of the globe that have sensitive soil but no acid rain problems. That is because there are no significant sulfur emissions in that area. Study the prevailing winds (page 3 of the webquest) and describe where the sulfur emissions would need to come from to cause acid rain problems in that area.

4World Energy Consumption and Population

8. What percent of the world's population lives in North & Central America? 9. What percent of the world's energy consumption is used by North America and Central America (listed as Latin America on the energy consumption chart)? 10. Is there any other region of the world that uses as much energy as North America? 11. Why do you think there is such a difference between the percentages in question 8 and 9? 12. Identify an area of the world with a high population and low energy consumption. What might explain this?
