Unit 1 Flashcards
Properties of distribution
Density, Concentration and Pattern.
Density
number of things in a specific area
Concentration
clustered, dispersed
Pattern
how things are arranged in a certain place
Reference maps
Shows physical geography of a place. (ex: Boundaries, physical features, etc)
Thematic maps
Shows how phenomenon are distributed (ex: population, climate, etc.
Types of Thematic maps
Choropleth, Cartogram, Dot, graduated symbol and Isoline.
Choropleth
shading or coloring indicates different values.
Cartogram
distorted shape to show emphasis.
Dot
more of something=more dots
Graduated Symbol
Symbol’s size depends on how much there is
Isoline
Lines join all points that have same value
Modern Geographic tools
Remote sensing, GIS and GPS
Remote sensing
scanning earth by satellite or aircraft
GIS
Geographic information system
GPS
Global positioning system
Absolute location
exact location of an object
examples of Absolute location
address, Latitude and Longitude, North, South, East and West.
Relative location
Description of location
Distance decay
The interaction between two things decrease as the distance between them increases.
Ex: Radio signals
Friction of Distance
when things are further apart, they tend to be less well connected
Environmental Determinism
Environment determines how and where humans will live.
Possibilism
Environment influences but humans find a way around
Scale
amount of detail
Small scale
not detailed. ex: globe
Large scale
zoomed in, more detail
Location
position that a point occupies on Earth
Absolute location
exact location of an object. coordinates
Relative location
description of where a place is.
place
location distinguished by physical and human characterisitcs
Site
refers to absolute location and physical character of a place
Situation
location of a place relative to another place
Time-space compression
describes the processes causing the relative distance between places to shrink.
Region
area that is different from other areas because of certain characteristics.
3 types of regions
formal, functional and perceptual
Formal region
an area that has one or more shared traits. can by physical, cultural or a combination of traits.
Functional region
defined as an area by its function around a focal (center) point.
examples of formal region
Rocky Mountains, Great Plains
examples of functional region
Airline flight routes, service area of pizza shop.
Perceptual region
reflects peoples feelings and attributes towards a place.
examples of perceptual region
The Midwest, Eastern Europe.
World System Theory
developed by Wallerstein. describe spatial and functional between countries and world economy.
Core countries
Highly interconnected, good transportation and communication, good networks and infrastructure etc. Ex: Unites States, Japan, Australia
Peripheral countries
less stable governments, poor medical care, inferior communication and transportation, etc.
semi-peripheral
process of industrializing, active in manufacturing and exporting goods, have potential to become a core country.
