4. Prime Meridian: an imaginary line that goes all the way around the earth dividing it into two halves, an eastern half and a western half
**Prime Meridian passes through Greenwich, England**

5. Eastern Hemisphere: the half of the earth that is east of the Prime Meridian Western Hemisphere: the half of the earth that is west of the Prime Meridian

6. North Pole: the point on the earth which is furthest north South Pole: the point on the earth which is furthest south

7. Lines of Latitude: imaginary parallel lines that run east to west around the earth, also called parallels **Measured in degrees N and S**

9. Lines of Longitude: imaginary lines that run north to south around the earth, also called meridians **Measured in degrees E and W**
