| Dispersion/Concentration | The spreading of redistribution of ideas, goods and people/ to bring people, goods and ideas toward a common center |
| Distance | The measurement of the physical space between two places |
| Friction of Distance | A measure of how much absolute distance affects the interaction between 2 places |
| Distortion | To twist or stretch out of the original or normal shape, as in creating a flat map from the spherical shape of the earth |
| Distribution | The division, sharing and delivery of goods, people, services and ideas |
| Environmental Determinism | The view that the natural environment has a controlling influence over various aspects of human life, including cultural development |
| Equator | 0(degree) latitude, divides the northern and southern hemispheres |
| Geocaching | A hunt for a cache using the GPS coordinates which are placed on the internet by other geocachers |
| Geographic Information Systems (GIS) | A computer hardware and software system that handles geographically referenced data. A GIS uses and produces maps and has the ability to perform many types of spatial analysis |
| Global Positioning System | A set of satellites used to help determine location anywhere on the earth's surface with a portable electronic device |
