| 3. Absolute Location | The position on Earth in which a place can be found |
| 4. Hemisphere | A half of the Earth, the equator divides the Northern and Southern hemispheres; the prime meridian divides the Eastern and Western hemispheres |
| 5. Relative Location | its relation compared to other places |
