1. Chapter 6: Views of EarthSection 2:Viewpoints Mr. MotukGeneral Science

2. Chapter 6 Section 2 Introduction to the Viewpoints of Earth How to Find Places on Earth Longitude and Latitude can be used as a precise way to determine location. System of imaginary gridlines.

3. Chapter 6 Section 2 Latitude Horizontal lines paralleling the Equator. Equator divides the Earth into Northern and Southern Hemispheres. Used to measure North and South Both poles are measured at 90 degrees. North Pole= 90 degrees North South Pole = 90 degrees South

4. Chapter 6 Section 2 Latitude

5. Chapter 6 Section 2 Longitude Vertical 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 2 Longitude

7. Chapter 6 Section 2 Using Lines of Longitude The 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 Line a. Opposite side of Earth to the Prime Meridian.

8. Chapter 6 Section 2

9. Chapter 6 Section 2 Latitude and Longitude can be broken down Degrees are the largest measure Degrees are divided into minutes Minutes are divided into seconds When writing coordinates latitude is always first When writing coordinates; latitude always comes first.

10. Chapter 6 Section 2 Earth Time What time is it on Earth? The answer actually depends on where you are located. The Earth is divided into 24 time zones. Each time zone is only one hour different from the next time zone. Every time zone is 15 degrees longitude wide. 6 time zones cover the United States.

11. Chapter 6 Section 2 Every time zone you cross going west time goes backwards. Every time zone you cross going East time goes forward.

16. Chapter 6 :Section 2 Calendar Dates New days begin at 12 midnight for the time zone. Crossing time zones gains or loses an hour. Traveling West: Minersville to California 9 am in Minersville, 6 am in California Traveling East: California to Minersville 1. 9 am in California, 12 pm in Minersville

17. Chapter 6 :Section 2 Crossing the International Date Line (180 degrees longitude) Gain or Lose one day Traveling West: Asia to the United States January 1st in Asia, December 31st in U.S.A. Traveling East: United States to Asia January 1st in United State, January 2nd in Asia Question? If you leave NYC at 11:00 am and your flight lasts 5 hours, what time is it in San Diego when you land?
