D199 Physical Human Geo || All Answers Are Correct 100%.
earliest maps correct answers written on clay tablets with stick; figurative maps
Reference Maps correct answers display the anatomy of a geographic area ex. routes, rivers,
bodies of water
thematic map correct answers maps that emphasize a specific subject area or theme across a
geographic area ex. population, vegetation
Early greek maps correct answers Greeks traveled the mediterranean sea, and created pretty
accurate maps of the surrounding area; among the first scholars to discover earths circumference.
medieval maps correct answers (1100-1400) increase in the European use of figurative mapping
to advance religious beliefs ex. T and O map
medieval maps correct answers Al-idrisi, arab cartographer created accurate literal maps as he
traveled the mediterranean sea
Age of Exploration correct answers European countries explore; rapid increase in creation of
literal maps for navigation. Maps have more military, political, historical, and economic value as
Europe and Asia staking claims and sailing ships. ex. Map of Historical
Emporor+King+Border+Terrain
thematic map rise correct answers Late 1600s the use of thematic mapping increases
Analytical mapping correct answers Creating maps to answer questions Ex. Dr. Snow maps the
spread of cholera in 1854, and discovers the source
Geographic Information System (GIS) correct answers using computers to create maps.
computers better at analyzing, manipulating, and layering than cartographers.
scale correct answers map units: real world units
Projections correct answers turning a 3D lumpy globe into 2d projections
developable surface correct answers A geometric shape such as a cone, cylinder, or plane that
can be flattened without being distorted. Many map projections are classified in terms of these
shapes.
conformal projections correct answers accurately depict shape of geographic areas while
distorting area/size; commonly used for large scale mapping wtfm ex. Mercator projection,
geography closer to the poles speaks to be bigger than it is in relation to geography closer to the
equator
equal area projections correct answers depicts the accurate relative size of geographic location
but distorts shape ex. Galls Peter projection, shows true size but shearing and compression
occurred
equidistant projection correct answers depicts accurate distance, but distorts shape + size; useful
for mapping flights or earthquake epicenter ex. azimuthal equidistant projection all geographic
areas accurate distance + direction from a center point
compromise projection correct answers maps that make a compromise to create the least amount
of distortion of each type ex. Robinson projection
interrupted projection correct answers tears globe into sections to accurately depicts shape and
size but distort distance ex. Goode Homolone Projection 1923- globe in 4 sections
thematic map types correct answers dot density, proportional symbol maps, and chloropleth
, Dot Density Map correct answers each dot/point is same size and represents a value of a specific
feature. dots @ an average location to maintain privacy; help visualize cluster/density
Proportional Symbol Map correct answers uses one symbol of different sizes to represent the
magnitude or amount of a specific feature; map makers have to find a balance between ranging
symbol size + limiting overlap; symbol size not affected by land area
chloropleth map correct answers uses different hues to depict different amounts of a specific
feature; darker = higher value; easy to interpret, but doesn't depict variations within specific
zones
standardization correct answers scaling quantities expressed on a map so that information
presented equivalently across all geographic locations; ex. people per square mile used
frequency table correct answers A table for organizing a set of data that shows the number of
times each item or number appears.
Histogram correct answers similar to a bar graph but x variable is a range of one classification
ex. age
bins correct answers the columns or bard on a histogram
frequency polygon correct answers instead of bars, one dot place at the top of where each bar
would be, and all dots connected. starts and ends on the x-axis
density curve correct answers the edges of a frequency polygon are smoothed to make curves
center correct answers the midpoint of data, can be determined from shape or from mean or
median
spread of data correct answers can be symmetrical, skewed left, or skewed right
shape correct answers the countour of a graph
categorical variables correct answers qualitative variables such as names and labels
univariate data correct answers one variable ex. age
bivariate data correct answers 2 variables ex. life expectancy and GDP
Dot Plot correct answers dots stack in a line across values on x axis (only 1 axis)
Scatterplot correct answers each data point plotted as a dot on a (x,y) graph
direction correct answers the overall trend or tendency of a graph ex. slanting up or down
