Why Is Each Point on Earth Unique?

--Location--

A place is a specific point on Earth distinguished by a

particular characteristic.

Describing the features of a place is an essential

building block for geographers to explain similarities,

differences, and changes across Earth.

Geographers describe a feature’s place on Earth by

identifying its location, the position that something

occupies on Earth’s surface.

Absolute location

Mathematical location

Latitude & Longitude

degrees, minutes, seconds

Township & Range (1785 Land

Ordinance)

Subdivision: parallels &

meridians

Topographic quadrangle,

US Geological Survey

Metes & Bounds

Relative location

“place” in relationship to

surroundings

Location can be

identified in three

ways…

Toponym

Names derived

from people of

prominence,

religious

affiliation,

physical features,

or origins of its

settlers

St. Louis

St. Paul

Denali (formerly Mt.

McKinley)

Washington, D.C.

Athens

Rome

Charlotte

Site

Site is the physical

character of a place.

Physical & cultural

characteristics

Characteristics include

climate, water sources,

topography, soil,

vegetation, latitude, and

elevation.

absolute location concept

Examples of Site

Harbor Sites

New York City

Alexandria, Egypt

Istanbul, Turkey

Island Sites

Hong Kong

Singapore

Fall Line Sites

(where a river meets a waterfall)

Richmond,

Virginia became

a major city

because it is

located on the

fall line of the

James River

Confluence Sites

(cities located where rivers meet)

Pittsburgh, Pennsylvania

Khartoum, Sudan

Situation

Situation is the

location of a place

relative to other

places.

Examples of Situation

Command of land between the Tigris

and Euphrates Rivers

Baghdad, Iraq

Focal point of religious pilgrimage

Why Is Each Point on Earth Unique?

--Region--

An area on Earth defined by one or more distinctive characteristics

is a region.

Most often applied at two scales

1. Spanning political states

2. Constrained within one political state.

A region derives its unified character through the cultural

landscape─a combination of cultural, religious, and physical

features.

“Culture is the agent, the natural area the medium, the

cultural landscape is the result.” – Carl O. Sauer, American

Geographer

Geographers identify

three types of regions…

Formal Region

Aka Uniform Region or Homogeneous Region

Areas of essential uniformity

An area in which everyone shares in commone one

or more distinctive characteristics

Physical or cultural

Common language, economic activity, or climate

Characteristic may be predominant rather than

universal.

Sahara Desert, “Bible Belt”

Functional Region

Aka Nodal Region

An area organized around a

node or focal point

Spatial system defined

by interactions/

connections

The characteristic chosen to

define a functional region

dominates at a central

focus or node and

diminishes in importance

outward.

Circulation of a newspaper,

such as The New York Times

Newspaper Route

Perceptual Region

Aka Vernacular Region

Less structured & more

culturally based

An area that people

believe exists as part

of their cultural

identity.

The American South is

a region individuals

recognize as having

distinct environmental,

cultural, and economic

preferences.

Globalizing Processes (5)

Scale

spatial interaction

Accessibility

how easy/difficult to overcome time & space separation

Connectivity

how places are connected

Spatial diffusion

process of dispersion of ideas or items from a center of origin to more distant points

Globalization

Increasing interconnection of peoples and societies worldwide

Time-space compression

With globalization comes idea that the word is shrinking – ability of person, object or idea to interact with a person, object, or idea into another place is fast-paced –

Result is a world that is more uniform, integrated, interdependent

Pattern (Spatial Distribution)

Space refers to the physical gap or

interval between two objects.

Geographers think about the

arrangement of people and

activities in an attempt to try to

understand why they are in such a

distribution = Arrangement of

items on Earth’s surface

Density

Concentration

Pattern

1. density

frequency with which

something occurs in space

Measure of the

number/quantity within a

defined unit of areas

2. concentration

Extent of a feature’s spread over space

clustered, agglomerated = closely spaced

together

dispersed, scattered = relatively far apart

3. pattern

Geometric arrangement of objects in space

Emphasizes design rather than spacing

linear (a) – road, river, rail line

centralized (b) – city & suburbs

random (c)

Globalizing

Processes

People, ideas,

and objects

move via

connections

through one of

three types of

diffusion.

Relocation Diffusion

Expansion Diffusion

Hierarchical

Diffusion

Contagious

Diffusion

Stimulus Diffusion

Relocation Diffusion

Spread of an idea

through physical

movement of people

from one place to

another

Ex. Language brought

to a new locale by a

migrant

Hierarchical Diffusion

spread of an idea

from persons or

nodes of authority

or power to other

persons or places

Contagious Diffusion

rapid, widespread

diffusion of a

characteristic

throughout the

population

Stimulus Diffusion

Spread of an

underlying principle

even though a

characteristic itself

apparently fails to

diffuse.

Ex. Innovative

features of Apple’s

iPhone and iPad have

been adopted by

competitors.

Associations

among

phenomena in an

The uniqueness

(or sameness) of

an area

“… the forms

superimposed on the

physical landscape

by the activities of

man.” – Carl O.

Sauer, American

Geographer

The cultural landscape has the ability to communicate to people what

the accepted norm is within a place.

Culture is the body of customary beliefs, material traits, and social

forms that together constitute the distinct tradition of a group of

people.

Culture: What People Care About

Geographers study why the customary ideas, beliefs, and

values of a people produce a distinctive culture in a particular

place.

Especially important cultural values derive from a group’s

language, religion, and ethnicity.

Culture: What People Take Care Of

The second element of culture of interest is production of

material wealth, such as food, clothing, and shelter that

humans need in order to survive and thrive.

Cultural Ecology

Concerned with culture as a system of

adaptation to and alteration of the

environment

Two theories:

Theories

Environmental Determinism – physical environment caused social development

Possibilism - physical environment may limit some human actions, but people have ability to adjust to their environment

Why Are Some Human Actions Not Sustainable?

Sustainability and Resources

Geographers observe two major misuses of resources:

Humans deplete nonrenewable resources.

Humans destroyed otherwise renewable resources through pollution of air, water, and soil.

Three Pillars of Sustainability

1. Environment Pillar

Sustainable development can only exist if conservation is embraced more fully than

wasting resources or preservation of all resources.

2. Economy Pillar

Efforts to set prices of commodities and goods based not only on supply and demand but

also on costs to the environment.

3. Society Pillar

Modifying the wants of cultures in regards to shelter, food, and clothing to objects that

are sustainable

Why Are Some Human Actions Not Sustainable?

Interactions in the Biosphere

People are now the most important agents of change on Earth.

Human modification of the abiotic systems has ongoing

ramifications.

Examples

Atmosphere contains pollutants, humans have trouble

breathing.

Without water, humans waste away and die.

Excessive extraction of resources from lithosphere limits

availability of materials for building and fuel for energy.

Excessive erosion or depletion of nutrients limits

biosphere’s ability to provide food for humans.

Why Are Some Human Actions Not Sustainable?

Modifying the Environment

Few ecosystems have been as thoroughly modified as those of the

Netherlands and Florida.

Netherlands

Much of the Netherlands would be underwater, if it weren’t for polders-

a piece of land that is created by draining water from an area.

Dutch have become world leaders in reducing the causes of global

warming and industrial pollution.

Florida

Unsustainable modifications made to ecosystem, as a result of draining

portions of the Everglades and water pollution from cattle grazing
