  23. 23. Typical Graph • This is an example of a typical graph we are all familiar with. • The graph is made up of different “points” with lines that connect the points.
  24. 24. Typical Graph •Each point has two values: • The “X” value that runs along the horizontal “X” axis •The “Y” value that runs along the vertical “Y” axis Y axis X axis
  25. 25. • X value is always stated first • Followed by the Y value • The “origin” is the point where the 2 axes intersect with a value of (0,0) (0,0) (3,8)Y X (9,5)
  26. 26. • A point can also have negative (-) values • Negative X values are to the left of the origin (0,0) • Negative Y values are below the origin X Y (-X,+Y) (+X,-Y) (+X,+Y) (-X,-Y) (0,0)
  27. 27. East West, North South on The Earth • Let the X axis be the Equator. • Let the Y axis be the Prime Meridian that runs through Greenwich outside of London. • Lat/Long are the 2 grid points by which you can locate any point on earth. Y X
  28. 28. East West, North South on the Earth • Let each of the four quarters then be designated by North or South and East or West. N S EW
  29. 29. East West, North South on the Earth •The N tells us we’re north of the Equator. The S tells us we’re south of the Equator. •The E tells us that we’re east of the Prime Meridian. The W tells us that we’re west of the Prime Meridian. (N, W) (N, E) (S, W) (S, E)
  30. 30. East West, North South on the Earth • That means all points in India will have a North latitude and a East longitude because it is North of the Equator and East of the Prime Meridian. (N, E) Prime Meridian
  31. 31. East West, North South on the Earth •What would be the latitude and longitude directions in Australia? Prime Meridian If you said South and East , you’re right!
  32. 32. What is Latitude? • Latitude is the distance from the equator along the Y axis. • All points along the equator have a value of 0 degrees latitude. • North pole = 90°N • South pole = 90°S • Values are expressed in terms of degrees. Y X 90°S 90°N
  33. 33. What is Latitude? •Each degree of latitude is divided into 60 minutes. • Each minute is divided into 60 seconds. Y X 90°S 90°N This is also true of longitude.
  34. 34. What is Latitude? •For Example: •37°, 02’,51’’N •This is close to the latitude where you live. Y X 90°S 90°N
  35. 35. What is Longitude? • Longitude is the distance from the prime meridian along the X axis. • All points along the prime meridian have a value of 0 degrees longitude. • The earth is divided into two parts, or hemispheres, of east and west longitude. Y X 180°W 180°E
  36. 36. What is Longitude? • The earth is divided into 360 equal slices (meridians) • 180 west and 180 east of the prime meridian Y X 180°W 180°E
  37. 37. What is Latitude? •Our latitude and longitude might be: •30°, 44’,13’’N •76°, 47’, 14’’E •Chandigarh Y X 90°S 90°N
  38. 38. So Where is (0,0)? •The origin point (0,0) is where the equator intersects the prime meridian. •(0,0) is off the western coast of Africa in the Atlantic Ocean.
  39. 39. See If You Can Tell In Which Quarter These Lon/Lats Are Located • 1. 41°N, 21°E • 2. 37°N, 76°W • 3. 72°S, 141°W • 4. 7°S, 23°W • 5. 15°N, 29°E • 6. 34°S, 151°E A B C D
  40. 40. •1. B •2. A •3. C •4. C •5. B •6. D
  41. 41. •See if you can find those same latitude/longitude locations on a map!

  46. 46. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 Why so many Time Zones? North Pole 15° 1 revolution of Earth = 365.25 days 6 hours x 4 years = Leap year & we catch up 1 rotation of Earth = 24 hours Circle = 360° 360° /24 = 15° = 1 hour Earth rotates 15° each hour At the equator Earth ≈ 24,900 miles = 1037.5 miles in an hour
  47. 47. Likened to a Number Line ADD and hour for each time zone as you move EAST SUBTRACT an hour for each time zone as you move WEST - 0 + Your place of origin
  48. 48. World Time Zones
  49. 49. • Areas of the world on non- standard time • 2 South Pacific islands • India • Afghanistan • Nepal • Iran • Sri Lanka • Newfoundland • Central Australia • Myanmar (Burma) Non- Standard Time The deviation of time keeping from the standard time zone in which a place is geographically located. The usual deviation occurs in quarter hour increments, i.e. 15 minutes, 30 minutes, or 45 minutes.
  50. 50. USING WHAT YOU HAVE LEARNED True or False: If EVERY part of the statement is TRUE, write T. If ANY part of the statement is FALSE, write F. 1. The earth makes one complete rotation every 24 hours. 2. For every 15° of longitude, there is a difference of one hour in time. 3. Time zones always have straight boundaries. 4. It is 12 noon everywhere on the earth at the same time. 5. The letters a.m. stand for the 12 hours before 12 noon. 6. Post meridiem means the 12 hours after 12 noon. 7. The line of longitude at 180° is called the Prime Meridian. 8. When you travel across the International Date Line you stay in the same day. 9. When you cross the Prime Meridian, you stay in the same day. 10. It takes one hour for the earth to rotate 15°. True or False
  51. 51. 1. In what areas of the world do you find non-standard time? 2. You are in New York and you want to call someone in Rome, Italy, at noon Rome time. When would you call? 3. Assume that flying from New York to London requires 6 hours. When would a flight leaving New York on a Wednesday at 6:00 p.m. arrive in London? 4. You are flying from Los Angeles to Moscow. You leave Los Angeles at 10:00 a.m. on Saturday and you arrive in Moscow on Sunday at 9:00 a.m. How many hours did you actually spend flying? 5. You are planning a flight from Bombay, India, to Washington, D.C., that must connect through several cities. You will leave Bombay on August 2, at 8:00 A.M., and will continue directly through Beijing and Los Angeles to Washington, D.C. What time is it in Washington, D.C., when you begin your trip? What will be the date when you arrive in Washington, D.C.? 6. If it is 3:00 p.m. in Greenwich, what time is it in India? 7. If it is 9:00 A.M. in Cape Town, what time is it in Washington, D.C.? 8. If it is Tuesday, 4:30 p.m. in Japan, what day and time is it in Honolulu? 9. If it is Friday, 8:15 A.M. in Rio de Janeiro what day and time is it in Beijing? Time it! Practice

  68. 68. Fractions of a Degree • 1 degree = 60 minutes or 1 minute is 1/60th of a degree • Use minutes if location is not directly on the latitude/longitude line • Written ----- Degree/minute = XX° xx’ compass direction 30’ is half-way between degrees
  69. 69.  The world rotates (spins) 360° in 24 hours. 360° / 24 hours = 15° per hour  The world has 24 time zones, each l5° apart. THERE IS A 1 HOUR TIME DIFFERENCE FOR EVERY 15° OF LONGITUDE LONGITUDE AND TIME

  77. 77. India is one of the ancient civilizations in the world. It has achieved multifaceted socio economic progress during the last five decades. It has moved forward displaying remarkable progress in the field of agriculture, industry, technology and overall economic development. India has also contributed significantly to the making of world history.

  84. 84. Maharishi Valmiki has recorded in his Ramayan- (Yuudh Kand, sarg 22 and shlokas 45-73) that Shri Rama’s army constructed a bridge over the sea between Rameswaram and Sri Lanka. After crossing this bridge, Shri Rama’s army reached Sri Lanka, defeated Ravana and liberated Sita from his captivity. It is found exactly at the location narrated in Valmiki Ramayan
  85. 85. Space images taken by NASA reveal an ancient bridge in the Palk Strait between Bharat and Sri Lanka.
  86. 86. The existence of the bridge obviously cannot be denied! However to what extent there was manual intervention in connecting the gaps between the shoals, islands and rocks is a subject for detailed marine archaeological and geological research. This kind of research has never been carried out nor has any team been constituted so far. However, there is enough evidence about the existence as well as the use of this bridge in ancient Bharatiya history, literature and travelogues etc. 'Ramayana', which mentions a bridge between Rameshwaram (Bharat) and the Sri- Lankan coast, constructed under the supervision of the dynamic and invincible figure of Rama, who is the incarnate of the supreme.
  87. 87. Of the three major lines, Only Tropic of Cancer passes through India. Tropic of cancer passing through Indian states are as follows 1-Gujarat 2- Rajasthan 3- Madhaya Pradesh 4- Chattisgarh 5- Jharkhand 6- West Bengal 7- Tripura 8- Mizoram
  88. 88. Tropic of Cancer board near Bhopal, India
