7. Distance-decay Theory: The interaction between two places declines as the distance between them increases.
EX: N. America & N. Korea 8. GPS: Global Positioning System
USES: to help you get to a place you have never been to, to find where you are if lost, to find close places near you in categories of things. 9. Demography: The study of the characteristics of human populations, such as size, growth, density, distribution, and vital statistics.
EX: gender ratio, fertility rates, and literacy rates 10. Agricultural Density: The number of farmers per unit area of arable (farmable) land. 11. Physiological Density: The number of people per unit area of arable (farmable) land. 12. Arithmetic Density: The number of people per unit area of all land. 13. Ecumene: inhabited /inhabitable area of the world. 14. Non-Ecumene: uninhabited /uninhabitable area of the world. 15.

MDC- More advances in medicine and tools for operations
LDC- Still developing and learning how to create new advanced things for medical uses b) Why are they so different:
MDC- a country with a per capita whose GPD is over $10,000
LDC - is a country with a per capita whose GPD is below $10,000 17.

Carrying Capacity: The number or quantity of people or things that can be conveyed or held by a vehicle or container. 20. Overpopulation: Excessive population of an area to the point of overcrowding, depletion of natural resources, or environmental deterioration. 21. CBR, CDR, TFR, NIR: a) What is it:
CBR- Crude Birth Rate: # of births per 1,000 people a year.
CDR- Crude Death Rate: # of deaths per 1,000 people a year.
TFR- Total Fertility Rate: The average number of children a woman has throughout her childbearing years.
NIR-Natural Increase Rate: The percentage growth of a population in a year, computed as the crude birth rate minus the crude
