APES Unit 3b Flashcards
Urbanization
removing of vegetation to convert natural landscape to city
Urban Sprawl
population movement out of dense, urban centers to less dense suburban areas surrounding the city
what causes urban sprawl?
cheaper property in suburbs than cities, cars make it easy to get places, domino effect, residents leave, so businesses leave
smart growth
mandated urban growth boundaries, reinvest in existing infrastructure, design neighborhoods that have homes near shops, offices, mix land use, walk able neighborhoods
Environmental benefits
minimize air and water pollution, reduce greenhouse gas emissions, encourage cleanup and reuse of contaminated properties, preserve natural lands
biotic potential
max capacity of living things to survive and reproduce under optimal environmental resistance
Type 1
(k-select), high survivorship in early and mid life, rapid decrease in survivorship in late life as old age sets in
Type 2
(in between r and k) steadily decreasing survivorship throughout life
Type 3
High mortality early in life due to little to no parental care, few make it to midlife, even fewer make it to adulthood
example of type 1
bear
example of type 2
songbird
example of type 3
insect
Industrialization
the process of economic and social transition from an agrarian economy to an industrial one
Pre-industrialized/less developed
a country that has not yet made the agrarian to industrial transition, very poor, high death rate and high infant mortality, high TFR
Industrializing/developing
part way through this transition, decreasing death rate and IMR, rising GDP
Indsutrialized
completed transition, very low DR and IMR, very high GDP, low TFR
total fertility rate
average number of children a woman in a population will bear throughout her lifetime, high population growth rate
what does a high TFR mean?
high birth rate
Replacement Level Fertility
the TFR required to offset deaths in a population and keep population size stable
