Latitude & longitude class 2013 notes

  1. 1. INCLUDES NOTES FOR CLIMATE & TIMEZONES
  2. 2. MAP PART NOTES
  3. 3. Parts of a Map
  4. 4. Compass Rose Cardinal Directions Intermediate Directions
  5. 5. Mercator Projection – shows accurate direction, but land and water areas are greatly distorted toward the north and south poles.
  6. 6. RobinsonProjection– showsaccurateshape&sizeof continents,butwaterareasare expandedtofilltheextraspace.
  7. 7. Imagine a single dot on a ping pong ball. How would you describe its location? It would be quite difficult. The same is true of locations on the Earth's surface. Geographers have solved this problem by creating latitude lines and longitude lines.
  8. 8. Latitude defined…  Latitude: (parallels) imaginary lines going from the east to the west (right to left), but dividing the globe north to south.  They are called parallels because they never touch. These lines are measured in degrees.  Equator: an imaginary line that divides the earth into northern and southern hemispheres. It is the zero degrees latitude.
  9. 9. Divides Earth into Sections
  10. 10. Measured in Degrees
  11. 11. Important Latitude Lines Tropic of Cancer: 23 ½°N north of the equator. The farthest point north at which the sun can shine directly overhead. Tropic of Capricorn: 23 ½ °S south of the equator. The farthest point south at which the sun can shine directly overhead. Arctic Circle: 66 ½° N the frigid zone located directly on the center of the north pole. Antarctic Circle: 66 ½° S the frigid zone located directly on the center of the south
  12. 12. Lines of Latitude & Climate Now, color p10 in your i-Notes.
  13. 13. World Map
  14. 14. LINES OF LONGITUDE
  15. 15. Longitude Defined  Longitude – also called meridians; imaginary lines that extend from the North Pole to the South Pole  Prime Meridian – 0° longitude line, running though Greenwich, England.
  16. 16. Eastern Hemisphere Western Hemisphere
  17. 17. TIME ZONES
  18. 18. Int’l Date Line
  19. 19. Int’l Date Line Defined  International Date Line – an imaginary line on the Earth’s surface at 180° longitude, mostly through the Pacific Ocean, to the east of which the calendar date is one day earlier than to the west
  20. 20. Since its beginning, the International Date Line has zigzagged to avoid spitting apart countries into two days. It bends through the Bering Strait to avoid placing far northeastern Russia in a different day than the rest of the country. www.24timezones.com
  21. 21. Key Terms  time zone – The method of tracking the 24 hours throughout the 360 degrees of the earth’s circumference. Each time zone generally equals 15 degrees longitude.  standard time zone – a region in which the same time is used  daylight saving time – a plan in which clocks are set one hour ahead of standard time for a specific time for a specific period of time
  22. 22. More Key Terms  A.M. ante meridiem (Latin) – “before noon”  P.M. post meridiem (Latin) – after noon 360/24=
  23. 23. Putting it all together!
