• “To write about the earth”
• The world in spatial terms
• The study of places and regions
• Studies the location and distribution of
features on the earth’s surface
• Studies human activity, the natural
environment, and the between the two
relationship
• Answers where? and why?

Branches of Geography
Physical: studies where and why natural forces occur as they do; ex. Climates, landforms, vegetation.
Human: studies where and why human activities are located where they are; ex. religions, businesses, cities.

Most of the area of New Orleans flooded after Hurricane Katrina was majority African American. Physical and political geography intersect in analyzing the impacts of the natural disaster

Maps: Tool of Geography
• Map: tool for storing reference material and for communicating geographic information
• Modern cartography (the art and science of map-making)
– Images from space craft
– Geographic information systems (GIS)
– Maps of intangible features

Mental map
On a blank piece of paper, draw a map of your favorite childhood landscape.
• Draw and label your home, places you encountered regularly as you went about your life, your friend’s home, your school, etc.
•Let your mind recall the objects, and experiences that were important to you.
Don’t worry about creating a work of art –just make a map that reflects your experiences as you remember them.

• Landscape Observation
•Description of the earth’s surface and consideration of the environment.
• Spatial Analysis (the study of how people, objects or ideas are or are not related to one another across space)
•The use of different scales of analysis (spatial feature of your childhood at a detailed local scale)
• Cartography: the making of maps

Scale and Scope• Small scale:
– Large area
– General view
– Little detail
• Large scale:
– Small area
– Much detail
Which is better? Depends on map’s purpose.

Moving a 3D Globe to a 2D piece of paper cannot be done without distortion.
Globes are made into maps because they are bulky and not easy to carry.

Wilmington’s excellent situation has helped it grow and prosper. Wilmington is situated along the major highway of I95 and is situated between Baltimore and Philadelphia. Its situation between two major cities has increased Wilmington’s trade.
Wilmington’s site is next to the Delaware River. The Delaware River gives easy access to Philadelphia, to the C&D Canal, and to the Atlantic. This makes Wilmington’s situation excellent for transporting goods made in Wilmington to other locations and for importing goods to distribute to other places.

World Geographic Realms
• Realms are– based on spatial criteria
– the largest geographic units into which the world can be divided
– based on both physical (natural) and human (cultural) features
![Page 21: Memorizing places and physical features? Making maps?udel.edu/~browning/Intro_a.pdf · · 2010-07-13•Studies human activity, the natural environment, ... Physical and political](https://reader036.fdocuments.us/reader036/viewer/2022070608/5ac1c8207f8b9a433f8d4469/html5/thumbnails/21.jpg)
• Areas of the earth’s surface marked by certain properties
• Based on criteria we establish
• Criteria (indicators) can be:
– Human (cultural) properties
– Physical (natural) characteristics
– or both
• Regions are smaller and more detailed than realms
• All Regions have an area, boundaries, location

What are some of the problems in defining regions?
![Page 23: Memorizing places and physical features? Making maps?udel.edu/~browning/Intro_a.pdf · · 2010-07-13•Studies human activity, the natural environment, ... Physical and political](https://reader036.fdocuments.us/reader036/viewer/2022070608/5ac1c8207f8b9a433f8d4469/html5/thumbnails/23.jpg)
• Where geographic realms meet, transition zones, not sharp boundaries, mark their contact
• These zones are areas of spatial change where peripheries of two adjacent realms or regions join
• Zones are marked by a gradual shift (rather than a sharp break) in the characteristics that distinguish neighboring realms
e.g.
Transition Zones

• Marked by a certain degree of homogeneity in one or more phenomena
• Also called uniform regions or homogeneousregions
Formal Regions
Examples:
- Corn Belt
- Megalopolis

Types of Regions: Formal, Functional, Perceptual
The seven countries of Central America form a formal region because the borders of Central America are clearly between Mexico and South America.
The “Bible Belt” is a perceptual region because it has no clear borders, but is defined by areas perceived to be very Christian and conservative.
Economic areas such as wheat production areas are defined in terms of functional regions where the boundaries of the region are zonal and not straight lines. The region mapped here represents wheat production.

A region marked less by its sameness than its dynamic internal structure
Functional Regions
Example: Los Angeles Metropolitan Area
• A spatial
system focused
on a central core
• A region formed
by a set of
places and their
functional
integration
• Also called a
nodal region

• Literally means country behind
• A term that applies to the service area “behind” (often surrounding) an urban center
• An urban center is the focus of goods and services produced in the hinterland, and is the hinterland’s dominant focal point and market as well
