Unit 1 Flashcards
What is GIS
Comp system that has data that makes maps using layers
4 types of distortion
Shape, relative size, direction, distance
What happens when you cross the international date line going west toward asia?
You go forward a day
How many sats. for GPS to work
4
Mercator projection
Displays land masses better distorts at poles rectangular map
Who won the prize for whoever could measure longitude
John Harrison
When you cross the internation date line going east toward the usa what happens
You go back a day
How did john harrison win the prize to measure longitude
He make a clock thing with no pendulum
Robinson projection
Displays oceans better land areas are smaller
How many GPS sats do we have total
24 total 3 in reserve
Demography
Study of pop characteristics
What is pop distributed by (2)
Concentration and density
What is concentration displayed on
Cartogram
Why is census controversial
Nonparticipation and sampling
Characteristics of 4 pop clusters
Low lying areas with fertile soil and a temperate climate near ocean or river
4 pop cluster
East asia
South asia
Southeast asia
Europe
Where is east asia clustered around amd why
Pacific ocean bc inside of china is used for farming
What countries are in East asia
China japan koreas taiwan
What countries are in south asia
India pakistan bangladesh and sri lanka
Where is largest concentration in south asia
Along plains and the ganges river
Where is largest concentrations in europe?
Around big landmarks rivers and coalfields
4 areas human avoid living in
Too dry
Too wet
Too cold
Too mountainous
Ecumene:
Part of earth with permanent human settlement
Why is too wet bad?
The combo of heat and rain depletes soil nutrients for agriculture
Permafrost:
Permanently frozen land
Arithmetic density: and how to find it
Total number of objects in an area # of people divided by land area
Physiological density: and how to find it
Number of people supported by 1 unit of arable land
Agricultural density:
# of farmers to amount of arable land How effecient the country is
World NIR
1.2
Doubling time:
of years it takes for a pop to double itself assuming constant NIR
TFR:
Avg # of children a woman has
Childbearin years
15-49
World TFR:
2.5
Dependency Ratio:
of people who are too young ir old to work compared to # of people in labor force
Age of dependents in dependency ratio
0-14 and 65+
Sex Ratio:
of males per 100 females in the pop
IMR:
Number of deaths of infants up to age 1
DT:
Process of change in a societys pop from high CBR and CDR to low CBR and CDR and low NIR and high total population
Qualities of stage 1 (3) DT
High CBR amd CDR with no long term NIR no country left in stage 1 mostly hunting and gathering for food
Qualities of stage 2 DT
Rapid declining CDR and very high CBR high NIR
What pushed europe and north america into stage 2
Industrial revolution
What pushed africa asia and latin america into stage 2
Medical revolution
Qualities of stage 3 DT
CBR rapidly declining CDR declining NIR moderates
Why does the NIR decrease in stage 3
Women are having fewer kids bc they are living in urban areas where a big fam isnt an asset anymore also bc IMR has decreased
Qualities of stage 4 DT
Low CBR and CDR no long term NIR
What is TFR of ZPG?
2.1
Why less babies in stage 4
Women join labor force and birth control methods are easier to access
Who is Thomas Malthus
Guy who said world pop was outpopulating our food supply
Why do critic say Malthus was wrong about resource depletion
Bc his idea was that Earths resources are fixed and not expanding
Why do critics say Malthus was wrong about population growth in his theory?
Bc a bigger pop means more jobs to come up with more ideas on how to be more productive in food production
Was Malthus right?
He was right about food production but not on population growth
Why is Japan’s population declining
Bc they arent encouraging immigration
Why no immigration in Japan
Bc they place high values on social conformity and people are growing old and cant work
What are the Japanese doing to help with their declining population
They are encouraging older people and women to join the labor force by offering more health care at home and better money
2 big breaks in DT
Sudden drop in CDR from tech. innovation
Sudden drop in CBR from changing social customs
Elderly support ratio:
of working age people divided by # of people 65+
What did India do to reduce CBR
Sterilization camps and payment to those who did
What did china do to reduce CBR?
One child policy fams get payed to have only one child
Epidemiologic Transition:
Focuses on distinctive health threats in each stage of DT
Epidemiology:
Branch if medical science concerned with the incidence distribution and control of diseases that are in a pop at a certain time and are made by some special causes not usually present in affected locality
What was Stage 1 of the ET (epidemiologic transition)
Pestilence and Famine
High CDR
Qualities of stage 1 of ET
Infectious and parasitic diseases were main cause of death, animal attacks, black plague
Where did the black plague originate
Kyrgyzstan
How did the black plague diffuse
By fleas and rats on ships and trading posts
What was stage 2 of ET
Receding pandemics
Rapidly decling CDR
