WGU D199 Introduction to
Physical and Human
Geography - D199 2024/2025
EXAM WITH 100%
CORRECT AND VERIFIED
ANSWERS
immigrants
people moving into a geographical area
emigrants
people moving out of a geographical area
net migration
the difference between the number of immigrants and the number of emigrants for a
given geographical area in any given year
return migration
permanent return of emigrants to their country of origin
travel visas
documents that give temporary permission to enter a country
brain drain

a wealthy country's recruiting the "best brains" from a poorer country by offering higher-
paying opportunities
brain gain
benefits a receiving country experiences when highly skilled immigrants are lured away
from their country of origin when they accept higher-paying opportunities
brain waste
situation that occurs when a receiving country fails to take advantage of all the skills of
an immigrant population
push factors
conditions that encourage an individual to move from a location
pull factors
conditions that influence migrants to move to a particular location
reference maps
maps used to display important physical elements of a specific geographic area, such
as countries, rivers, mountains, etc.
thematic maps
specialized maps used to understand one particular attribute or characteristic of a
specific geographic area; examples are population maps, weather maps, and maps
illustrating the spread of disease
literal maps
maps that strive to display the objective truth about a specific geographic area
figurative maps

maps that use symbols to represent a narrative or point of view; they are much less
concerned with physical accuracy than are literal maps
analytical mapping
the use of cartography techniques to uncover and learn about patterns and trends in a
specific geographic area
map scale
how the measurement of distance on a map corresponds to the distance on the ground
in the real world
representative fraction (RF)
a way of describing the scale of a map by using a ratio
small-scale
a way of describing a map with a relatively small RF, where the various features of the
geography appear relatively small
large-scale
a way of describing a map with a relatively large RF, where the various features of the
geography appear relatively large
coordinates
the points on a specified reference system that define the location of a particular place
Cartesian coordinate system
a reference system for a plane (a flat surface) based on the work of mathematician
Rene Descartes, using x- and y-axes.
geographic coordinate system

Loading page 4...

the reference system devised to locate particular places on the surface of the earth,
using lines of latitude and longitude
longitude
one of a set of imaginary east-west lines that form part of the geographic coordinate
system
prime meridian
the line of longitude that passes through Greenwich, UK, which is the starting point for
counting the rest of the lines of longitude
latitude
one of a set of imaginary north-south lines that form part of the geographic coordinate
system
graticule
the grid pattern in the geographic coordinate system
projection
a method of "flattening" a globe into a form that can be represented on a flat surface
conformal projections
maps that preserve, in the process of projection, angles, although not necessarily
lengths
equal-area projections
maps that preserve, in the process of projection, the relative sizes of landmasses; they
do not, however, preserve shape well
equidistant projections

Loading page 5...

maps that preserve, in the process of projection, accurate distances from a central
point; they do not, however, preserve shape or size well
compromise, interrupted, and artistic projections
maps that blend characteristics to maintain as much accuracy as possible in distance,
size, and shape, conceding other characteristics; also, maps that have beauty as their
main objective
dot density map
a thematic map that uses points (dots) to represent the distribution (density) of a
particular attribute across a geographic area
proportional symbol map
a thematic map that uses symbols in different sizes to represent the distribution
(density) of a particular attribute across a geographic area; the larger the symbol, the
greater the density
choropleth maps
a thematic map that uses color (varying hues or varying saturations of the same hue) to
represent the distribution (density) of a particular attribute across a geographic area
standardization
in mapmaking, the process of defining the unit of measurement so that it can be
represented equivalently across a geographic area, rather than be distorted by other
characteristics, such as political boundaries
frequency table
a simple representation, in organized tabular form, of raw data
histogram

Loading page 6...

a type of graph that represents a data set visually, using continuous number ranges; it is
similar but not identical to a bar chart (which may not use continuous ranges)
frequency polygon
a type of line graph derived from plotting the points of a histogram's "bins" and
connecting them
shape
the visual contour of a frequency polygon or a smoothed-out form of it, using curves
center
the midpoint of a shape
spread
the extent to which the shape continues to either side of the center: symmetrically,
skewed-left, or skewed-right
density curves
frequency polygons that have been rounded into a continuous curve or curves rather
than being shown as a series of connected points
categorical variables
types of data organizations accomplished via qualitative labels rather than numerical
values
bar graph
type of visual representation of data organized into vertical rectangles, or bars, shown
on a plane defined by an x- axis and a y-axis
pie chart

Loading page 7...

type of visual representation of data organized by percentages of the whole, shown as
"slices" of "pie"
univariate data
a set of data that concerns one variable
dot plot
type of visual representation of data organized into a series of dots shown on axes
bivariate data
a set of data that concerns the relationships between two variables
scatterplot
type of visual representation of data where points are plotted on a plane defined by an
x-axis and a y-axis
direction
the overall trend of the data, usually either positive (slanting up) or negative (slanting
down)
positive linear association
as regards a bivariate data set, a description of the relationship of two data points sets
in which an increase in one causes an increase in the other
negative linear association
as regards a bivariate data set, a description of the relationship of two data points sets
in which an increase in one causes a decrease in the other
strength
