Chapter 6: Section 2 Notes (viewpoints of earth)

  1. 1. Chapter 6: Views of EarthSection 2:Viewpoints<br />Mr. MotukGeneral Science<br />
  2. 2. Chapter 6 Section 2<br />Introduction to the Viewpoints of Earth<br />How to Find Places on Earth<br />Longitude and Latitude can be used as a precise way to determine location. <br />System of imaginary gridlines. <br />
  3. 3. Chapter 6 Section 2<br />Latitude<br />Horizontal lines paralleling the Equator. <br />Equator divides the Earth into Northern and Southern Hemispheres. <br />Used to measure North and South<br />Both poles are measured at 90 degrees. <br />North Pole= 90 degrees North<br />South Pole = 90 degrees South<br />
  4. 4. Chapter 6 Section 2<br />Latitude<br />
  5. 5. Chapter 6 Section 2<br />Longitude<br />Vertical lines (called meridians) intersecting the poles. <br />Measure positions East and West on a globe. <br />Begin with the Prime Meridian (0 degrees Longitude)<br />

  7. 7. Chapter 6 Section 2<br />Using Lines of Longitude<br />The Prime Meridian (0 degrees longitude) runs from pole to pole through Greenwich, England)<br />West of the Prime Meridian is measured from 1 to 180 degrees West.<br />East of the Prime Meridian is measured from 1 to 180 degrees East. <br />The 180 degree meridian= International Date Line<br />a. Opposite side of Earth to the Prime Meridian. <br />
  8. 8. Chapter 6 Section 2<br />
  9. 9. Chapter 6 Section 2<br />Latitude and Longitude can be broken down<br />Degrees are the largest measure<br />Degrees are divided into minutes<br />Minutes are divided into seconds<br />When writing coordinates latitude is always first<br />When writing coordinates; latitude always comes first. <br />
  10. 10. Chapter 6 Section 2<br />Earth Time<br />What time is it on Earth?<br />The answer actually depends on where you are located. <br />The Earth is divided into 24 time zones. <br />Each time zone is only one hour different from the next time zone. <br />Every time zone is 15 degrees longitude wide. <br />6 time zones cover the United States. <br />
  11. 11. Chapter 6 Section 2<br />Every time zone you cross going west time goes backwards.<br />Every time zone you cross going East time goes forward.<br />
