Unit 1 Flashcards
Everything in unit 1
etymology of “geography”?
“Geo” means earth, “graphy” means to write
scale
the relationship between a distance on a map to that in reality (portion of earth to earth as a whole)
space
the physical gap between two objects
thematic map
a map that focuses on a geographic theme/pattern
GIS
software tools that store and analyze geographic data in layers.
GISci
the analysis of geographic data collected from satellite and other electronic technologies
remote sensing
the collection of data of the earth’s surface from long distance methods
GPS
geographic positioning system - connects to satellites to tell your absolute location and can be used for navigation
geotagging
the process of recording the location of a piece of information
the concept that determines the amount of area covered on a map and the level of detail it provides
map scale
three ways map scale can be expressed and how are they displayed?
ratio/fraction, written scale, and graphical scale
projection
the process of transferring locations of the earth’s spherical surface onto a flat map
four types of distortion resulting from projections
shape, distance, relative size, and direction
isoline map
lines connecting data points of the same value
dot distribution map
points representing data, where each dot represents a value
chloropleth map
a map where areas are shaded or patterned based off its value
graduated symbol
a map where symbols with varying sizes (based on its value) are placed on areas
cartogram
a map where the size of an area is distorted to be proportional to its value - graph in map form
atmosphere
a thin layer of gases surrounding earth
climate
the long term average weather condition in a certain area
Koppen’s climate classification
tropical, dry, warm mid-latitude, cold mid-latitude, and polar climates - divided based on precipitation and temperature
hydrosphere
all the water on the Earth’s surface’ and near it
lithosphere
Earth’s crust and a portion of the upper mantle
biosphere
all living organisms on earth
ecosystem
a group of living organisms and the abiotic spheres that interact with each other
equal area projection
area are proportional to the Earth’s surface, but shape, direction, and distance may get distorted, especially closer towards the poles
goode homolosine projection
separates Eastern and Western hemispheres. shape and size are accurate, but the directions and distances are distorted
mercator projection
rectangular map. accurate shape, but distorted size especially towards higher latitudes. good for navigation, but somewhat eurocentric.
galls-peters projection
rectangular map. accurate size, but distorts shape.
topographic map
a map that displays the physical features of an area
meridian (measured as longitude)
arc connecting the north and south poles, used to tell time
parallel (measured as latitude)
a circle drawn around the earth parallel to the equator
three ways to identify location
place name, site, and situation
toponym
the name given to a place
place
a point on earth distinguished by a certain physical and human characteristics
region
an area of earth distinguished by one or more characteristics
cultural landscape
the combination of cultural, economic, and physical features that give a region its unique character
formal/uniform region
an area with shared characteristics
functional/nodal region
an area that is organized around a node/focal point
vernacular/perceptual region
an area that exists within people’s identity, emerging from one’s perception
spatial association
the relationship between the distribution of one feature and the distribution of another
distribution
the arrangement of a feature in space
three properties of distribution
density, concentration, and pattern
