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

OROGRAPHIC

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.

CLIMOGRAPHS

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)

IMG-1653

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
