The graph is made up of different “points” with lines that connect the points. Y axis Each point has two Typical Graph values: The “X” value that runs along the horizontal “X” axis The “Y” value that runs along the vertical “Y” axis X axis Y (0,0) (3,8) X value is always Typical Graph stated first Followed by the Y (9,5) value The “origin” is the point where the 2 axes intersect with a X value of (0,0) (-X,+Y) (-X,-Y) A point can also Typical Graph have negative (-) values Y Negative X values are to the left (+X,+Y) of the origin (0,0) (0,0) X Negative Y values are below the (+X,-Y) origin East West, North South on The Earth Y Let the X axis be the Equator. Let the Y axis be the Prime Meridian that runs through X Greenwich outside of London. Lat/Long are the 2 grid points by which you can locate any point on earth. East West, North South on the Earth Let each of the N four quarters then be designated by W E North or South and East or S West. East West, North South on the Earth (N, W) (S, W) (N, E) (S, E) 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. East West, North South on the Earth (N, W) Prime Meridian That means all points in North America will have a North latitude and a West longitude because it is North of the Equator and West of the Prime Meridian. East West, North South on the Earth Prime Meridian What would be the latitude and longitude directions in Australia? If you said South and East , you’re right! 90°N Y 90°S Latitude is the distance What is Latitude? from the equator along the Y axis. All points along the equator have a value of 0 degrees latitude. X North pole = 90°N South pole = 90°S Values are expressed in terms of degrees. What is Latitude? 90°N Y X 90°S Each degree of latitude is divided into 60 minutes. Each minute is divided into 60 seconds. This is also true of What is Latitude? 90°N Y X 90°S For Example: 37°, 02’,51’’N This is close to the latitude where you live. What is Longitude? Y 180°W Longitude is the distance from the prime meridian along the X axis. All points along the prime meridian have a X value of 0 degrees longitude. The earth is divided into two parts, or hemispheres, of east 180°E and west longitude. What is Longitude? Y X 180°W 180°E The earth is divided into 360 equal slices (meridians) 180 west and 180 east of the prime meridian What is Latitude? 90°N Y X 90°S Our latitude and longitude might be: 37°, 03’,13’’N 76°, 29’, 45’’W The origin point So Where is (0,0)? (0,0) is where the equator intersects the prime meridian. (0,0) is off the western coast of Africa in the Atlantic Ocean.

TIME ZONES Math and Geography in Action Earth’s Seasons Why so many Time Zones? 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° North Pole 360° /24 = 15° = 1 hour Earth rotates 15° each hour At the equator Earth ≈ 24,900 miles = 1037.5 miles in an hour 15° Likened to a Number Line SUBTRACT an hour for each time zone as you move WEST - ADD and hour for each time zone as you move EAST 0 + Your place of origin World Time Zones 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. Areas of the world on nonstandard time 2 South Pacific islands India Afghanistan Nepal Iran Sri Lanka Newfoundland Central Australia Myanmar (Burma) True or False 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°. Time it! Practice 1. 2. 3. 4. 5. 6. 7. 8. 9. In what areas of the world do you find non-standard time? You are in New York and you want to call someone in Rome, Italy, at noon Rome time. When would you call? 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? 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? 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.? If it is 3:00 p.m. in Greenwich, what time is it in Moscow? If it is 9:00 A.M. in Cape Town, what time is it in Washington, D.C.? If it is Tuesday, 4:30 p.m. in Japan, what day and time is it in Honolulu? If it is Friday, 8:15 A.M. in Rio de Janeiro what day and time is it in Beijing? Latitude and Longitude Lines of longitude only Equator added Other lines of latitude added Cross-section through line of longitude Crosssection s throug h lines of Orange cut through lines of longitude Orange cut through lines of latitude Draw a map of this world. There are 4 countries: Red, Light Green, Dark Green and Purple. Latitude and Longitude Latitude lines run east/west but they measure north or south of the equator (0°) splitting the earth into the Northern Hemisphere and Southern Hemisphere. Latitude North Pole 90 80 Lines of latitude are numbered from 0° at the equator to 90° N.L. at the North Pole. 70 60 [ 50 40 30 20 10 ] 10 20 30 40 50 60 70 80 90 South Pole Lines of latitude are numbered from 0° at the equator to 90° S.L. at the South Pole. Latitude The North Pole is at 90° N The equator is at 0° latitude. It is neither north nor south. It is at the center between north and south. 40° N is the 40° line of latitude north of the equator. The South Pole is at 90° S 40° S is the 40° line of latitude south of the equator. Longitude Lines of longitude begin at the Prime Meridian. 60° W is the 60° line of longitude west of the Prime W Meridian. 60° E is the 60° line of longitude east of the E Prime Meridian. The Prime Meridian is located at 0°. It is neither east or west 180 ° East Longitude West Longitude North Pole Longitude N W PRIME MERIDIAN S Lines of longitude are numbered east from the Prime Meridian to the 180° line and west from the Prime Meridian to the 180° line. E Prime Meridian The Prime Meridian (0°) and the 180° line split the earth into the Western Hemisphere and Eastern Hemisphere. Prime Meridian Western Hemisphere Eastern Hemisphere Places located east of the Prime Meridian have an east longitude (E) address. Places located west of the Prime Meridian have a west longitude (W) address. INTERNATIONAL DATE LINE 180° SEPARATES 2 CALENDAR DAYS. America to Asia – gain a day Asia to America – lose a day By combining latitude and longitude, any location can be pinpointed A location’s coordinates (____° N or S, ____ ° E or W) Application N W E S North America is in the Northern Hemisphere because it is north of the Equator. North America is in the Western Hemisphere because it is west of the Prime Meridian. 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 LONGITUDE AND TIME 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 Greenwich, England is the logical starting point for time zones The world rotates west to east (counterclockwise), time zones to the east are ahead of the those time zones to the west ANOTHER CHEESY SAYING EAST INCREASE Time is forward to all places to the east WEST LESS Time is backward to all places to the west East Increase – West Less (1 hr per l5°) If it 9 p.m. at Position D, what time is it at position C? Position B? If it is 1 p.m. at Position X, at which location is the Earth rotates west to east Solar time is based on the position of the sun NIGHT IS FALLING ON EARTH Look at the East Coast of the United States. The lights are already lit. California the sun is still visible. This pictures shows AMERICAN CITIES at night. Saguenay Thunder Bay Toronto Sept-Iles St.John Ottawa It’s still daylight in California Québec Montréal Detroit Those light are Boston, New York, Philadelphia and Washington.
