EXAMPLES OF FORMAL REGIONS
*States- Texas, Florida, South Carolina, etc
*Countries- US, Mexico, Canada, etc
*Cities- Austin, Dallas, Houston, etc
*The area of town where the wealthiest people live.
*The Sahara Desert of Africa.
*U.S. city where more than 50% of residents speak Spanish.

Picture a bicycle wheel with a central axle in the middle of the wheel, which represents the center of all the activity. The spokes of the wheel represent links to outside areas (the tire) through transportation, communication and trade.
A perceptual region is defined by people’s feelings
