GIS Mapping
Migration
Horizontal; In relation to the Earths Equator
Vertical; in relation to Prime Meridian (invisible line drawn from North pole to South pole)
A tool to present geographic information visually
Absolute Location
Relative Location
The exact longitude and latitude of a precise point on Earth
A place located in relation to another place
GPS
(Global Positioning System) A tool that allows navigators to find their exact location.
Map Distortion
Definition: A Change in shape, size or position of Earth's features

Map Projections
Mercator
Distorts size but not shape
Ecology
Climate VS Weather
Weather: Conditions of atmosphere over a short period of time
How atmosphere behaves over a long period of time
5 natural factors that affect climate
Latitude
Closeness to large bodies of Water
(Only moderate changes): water moderated temperature. Ex. cool summers, warm winters
Orographic Affect
Elevation
higher elevation causes colder weather, lower elevation causes warmer weather
Ocean Currents
Warmer currents causes warmer weather and vice versa
Climographs
Plot monthly average precipitation and temperature for a given location.
Demography; the study of statistics involving birth rates, death rates, Dependency Ratios, etc.
Infant Mortality rate: (# of deaths/ #of live births) x 1000
Demography Transition Model (1-4)
Population Pyramids
Dependency Ratio; calculates rate of workers to non workers
( % under 15 years old + % over 65 years old / % 15-64) x 100
Push factors; Unemployment, drought, war, persecution, etc.
Pull factors; Promise of wealth, job opportunities, healthy economy, etc.
types of migration
interregional/Internal; moving from one region of a country, to another region of the same country
Transitional migration; occurs when migrants move from one country to another
Step Migration; occurs when people move up in hierarchy of locations (improving situation)
Chain Migration; occurs when when a pioneering individual or group settles in a new place, establishing a new migration foothold
Cyclical Migration; Occurs when workers migrate for temporary periods and then return to their home countries
Emigrating; moving from a place
Immigration; moving to a place
Geopolitics
Types of Border Disputes
definitional; a difference in definition, causing a confusion
Allocation; When a resource lies on both sides of territories. Who gets what?
Locational; where the boundary should be placed
Operational; when the border is established, but the problem is the movement between the borders
Ethnonationalism; when nations are (wrongly defined by a shared heritage, which usually includes a common language, a common faith, and a common ethnic ancestry

Forces
Centripetal Forces; things that bring the nation together. ex. a shared enemy, shared language, etc.
Centrifugal Forces; things that tear apart a country. ex. difference in cultures, etc.
Types of Boundaries
Geometric; a straight line border
Physical; defined by natural features. ex. mountains, rivers, etc.
Ocean Border/UNCLOS treaty
Territorial Zone; Up to 12 miles from shoreline of complete sovereignty; boats from other countries have 'Innocent Passage'
Contiguous Zone; 24 miles from coast where they still have some sort of sovereignty
Exclusive Economic Zone; 200 miles past shoreline where countries exercise only economic activities
Median Line Principle; if two countries are too close to each other for the UNCLOS treaty to apply, then a straight line will be drawn between the two countries
States
Types of states
Fragment; a state that is separated by a physical or human barrier (ex. Ocean or another state)
Prorupted states; Fairly compact with one large projecting extension
Compact State; distance from center to any boundary is about the same
Perforated; completely surrounds another state
Elongated; long and thin
Enclave state: A state completely surrounded by another one, but not ruled by it
Exclave State; a part of a state that is completely separated from the main part of the state.
Sectors of the Economy
Primary: economic activity that involves harvesting raw materials from the earth
Tertiary: Selling finished products of moving them around. Mostly service jobs (army, doctor, etc). Restaurants are also tertiary; even though you are making food
Secondary: taking raw material and turning it into something of greater value (manufacturing them)
Globalization
Pros: Can help catch up the poorer people/countries in the world
Cons: Means that everyone is relying on everyone
