Unit 1 Flashcards
- Maps are a flat representation of Earth's surface and can be used as a reference tool & communication (tell a story) - Geography is where things are found on Earth Human Geography is why -
Categories of Maps
A map that shows movment using lines and arrows
more value=bigger line
Flow-Line Map
Thematic Map
Categories of Maps
Map that uses colors and political boundaries
colors=values
Chloropleth Map
Thematic Map
Categories of Maps
Map has dots representing numbers
dots=value
Dot-Density Map
Thematic Map
Categories of Maps
Map that uses a big symbol to show the density in a particular area
bigger symbol=more valure
Proportional Map
Graduated Symbol

Categories of Maps
Map that doesnt follow political boundaries
color=value

crazy cartogram
Thematic Map
Categories of Maps
Map that shows where YOU believe something is
Cognitive Map

What are the 5 themes of geography
(hint acronym)
movement, region, human-environment interaction, location, place
M R. HE L P
Contemporary Tools
A system that determines the precise position of something on Earth through a series of satellites, tracking stations and receivers.
navigation devices
Global Positioning Systen (GPS)
A computer system that stores,
organizes, analyzes, and displays
geographic data.
google maps, zillow
Geographic Information System (GIS)
The acquisition of data about Earth’s
surface from a satellite orbiting the
planet or from other long distance
methods
Remote Sensing
Overlaying data on top of mapping source
Mashup
Location
4 elements of location
Topynym, site, situation, absolute location
Location
how does a place get its name
(topynym)
founder, famous person, religion, physical features, events, lure, settler origin
Projection
4 ways map projections are distorted
shape, area, distance, direction
(SADD)
Projection
4 classes of projection
conic, cylindric, plane, interrupted
Interaction
4 obstacles to interaction
physical barriers, cultural barriers, economic, distance decay
Density
Arithmetic Density
number of people per unit of land
Density
Pysilogical Density
number of people per unit of arable land
(farmable land)
Density
Agricultural Density
number of farmers per unit of arable land
(farmable land)
An area distinguished by a unique
combination of trends or features.
Region
A circle drawn around the globe parallel to the equator and at right angles to the meridians
Parallel/latitude
An arc drawn on a map between the North and South poles.
Meridian/
longitude
An area in which everyone shares one or
more distinctive characteristics.
Formal/Uniform/H
omogeneous Region
An area organized around a node or focal
point
Functional/Nodal
Region
An area that people believe exists as part
of their cultural identity.
Vernacular/Percep
tual Region
Actions or processes that involve the
entire world and result in making
something worldwide in scope.
Globalization
The spread of a feature or trend through
bodily movement of people from one
place to another.
Relocation
Diffusion
The spread of a feature or trend among
people from one area to another in a
snowballing process.
Expansion
Diffusion
The spread of a feature or trend from
one key person or node of authority or
power to other persons or places
Hierarchical
Diffusion
Diffusion
The rapid, widespread diffusion of a
feature or trend throughout a
population.
Contagious
Diffusion
Diffusion
The spread of an underlying principle,
even though a specific characteristic is
rejected.
Stimulus Diffusion
The diminishing in importance and
eventual disappearance of a
phenomenon with increasing distance
from its origin.
Distance Decay
The reduction in the time it takes to
diffuse something to a distant place as a
result of improved communications and
transportation systems
Space time
Compression
A nineteenth and early twentieth
century approach to the study of
geography which argued that the general
laws sought by human geographers could
be found in the physical sciences.
Geography was therefore the study of
how the physical environment caused
human activities.
Environmental
Determinism
The theory that the physical
environment may set limits on human
actions, but people have the ability to
adjust to the physical environment and
choose a course of action from many
alternatives.
Possibilism
What map is used most often for navigation
Mercator projection
only size distortion at poles
