Across
- 3. low population density outside of the city
- 4. low population density communities that are not directly connected to the metropolitan area

- 2. Cities and their suburbs actually create their own micro-climate and tend to be warmer than rural areas
- 6. Planting trees and crops together
- 7. fire that happens in areas that are poorly managed, lots of undergrowth allows fire to burn very hot and spread quickly from tree top to tree top
- 9. Parks and large areas of forest left in and around developments
- 10. Large expanses of undeveloped land covered mostly with grasses or brush suitable for grazing livestock but too dry to farm
- 12. When the urban area expands outward into the rural surroundings
