Midterm Review Flashcards
what are the advantages of Mercator (1569) projections?
- directions are shown accurately
- lines of latitude and longitude meet at right angles
Mercator (1569) projection disadvantages:
- distance between lines of longitude appears constant
- land masses near the poles appear large
- rectangle map
Robinson projection advantages:
- no major distortion
- oval shape appears more like a globe than does a rectangle
Robinson projection disadvantages:
-area, shape, size, and direction are all slightly distorted
what are the different types of thematic maps?
choropleths, dot distributions, graduated symbols, isolines, cartograms
what are the patterns observed in spatial analysis?
clustering (concentrated/dense), dispersal/distribution, patterns + spatial association
close together; dense (the # of something in a defined area)
far apart; distributed (the way something is spread out over an area)
define patterns + spatial associations;
indication that two (or more) phenomena may be related, associated, or correlated with one another; RELATIONSHIPS
what do population pyramids show?
age distribution, sex ratios, and dependency ratio
on a population pyramid, how do you analyze fertility rates? what conclusions can be drawn?
while analyzing a pop. pyramid, you can determine the TFR by looking at the women population (more women in the 15-49 yr range means a higher TFR).
based on our analysis, we can see whether a population in an area is growing in size or not, due to more or fewer children being born.
what types of challenges do societies with aging populations face?
- have to cover all the costs of having an aging pop.
- less young ppl in the workforce, meaning there are going to be more economic challenges; possibly resulting in raising taxes
