- 2. Chapter 6 Section 2Introduction to the Viewpoints of EarthHow to Find Places on EarthLongitude and Latitude can be used as a precise way to determine location. System of imaginary gridlines.
- 3. Chapter 6 Section 2LatitudeHorizontal lines paralleling the Equator. Equator divides the Earth into Northern and Southern Hemispheres. Used to measure North and SouthBoth poles are measured at 90 degrees. North Pole= 90 degrees NorthSouth Pole = 90 degrees South
- 4. Chapter 6 Section 2Latitude
- 5. Chapter 6 Section 2LongitudeVertical lines (called meridians) intersecting the poles. Measure positions East and West on a globe. Begin with the Prime Meridian (0 degrees Longitude)
- 6. Chapter 6 Section 2Longitude
- 7. Chapter 6 Section 2Using Lines of LongitudeThe Prime Meridian (0 degrees longitude) runs from pole to pole through Greenwich, England)West of the Prime Meridian is measured from 1 to 180 degrees West.East of the Prime Meridian is measured from 1 to 180 degrees East. The 180 degree meridian= International Date Linea. Opposite side of Earth to the Prime Meridian.
