8. 3.People are NOT evenly distributed over the surface of the earth. Why do people live in certain areas? water jobs transportation climate soil vegetation resources physical features Wealth war

9. 4.Most people live: on plains in the middle latitudes by rivers.

10. 4.Four areas which are mostly uninhabited: A.Polar and Tundra areas—Too cold. B.Tropics (near the equator). Too hot and wet. C.Deserts-1/4 of the earth’s surface. Too dry D.Mountains-too steep, rocky, cold, and soil is too thin

14. 7.Overpopulation: more people in an area than the resources can support. Is an area over populated? Geographers/Experts look at: a. birth rates b. death rates

15. What does the History of Population look like? Population density over time
