How to find your way . N E W The four Cardinal Points S

Latitude and Longitude Latitude Lines: Splits the earth into Northern and Southern hemispheres. The equator is the mid line of latitude, or PRIME PARALLEL (0 degrees latitude). As you move away from the equator, the degrees of latitude increase in both directions. Remember. ."flatitude"

Latitude lines run parallel to each other Much of the earth’s climate depends on these lines, because of the angle the sun hits.. . You will find different biomes somewhat organized according to latitude

and Longitude. . . (slice an apple) Runs vertically, North to South. The PRIME MERIDIAN is the 0 degree line of longitude Creates East and West Hemisphere on the earth. The Prime Meridian Also runs through Greenwich, England, Where international Time is based. (GMT – Greenwich Mean Time)

Together, you can find any spot in the world, using degree coordinates! For instance, 10 S (latitude) and 160 E (longitude) will land you at the city of Honiara, located in the Solomon islands. Every degree = ~111 km on the ground (between the Tropics)

Look at a “stripe” of Latitude, and a “stripe of Longitude Look at a “stripe” of Latitude, and a “stripe of Longitude. How are they different?

The Tropics = CANCER and CAPRICORN These are the 23ºN and S lines of latitude, which represent locations of direct sunlight in the summer and winter seasons.

Everyone knows that things don’t always land perfectly at a crossing point. . . So cartographers created a smaller grid system inside of each “box” to be more accurate, called minutes and seconds.

Earth has 24 time zones, bordered by lines that also run North to South on earth, and regulate clock time. Each time zone “slice” is about 15° of longitude each, and represents one clock hour.

Time Zones run the same direction as longitude lines, but are not perfectly straight like they are. . . WHY????

The International Date Line runs along the 180° line of longitude, which changes calendar days when crossed. Crossing toward the West moves a day ahead. Crossing East goes back a day

Daylight Savings: An Economic Decision Below, the yellow area indicates countries that practice “daylight savings”. What is the pattern you see? Why?

SUMMARY. . . Changing latitude changes daylight that affects CLIMATE Changing longitude changes daylight that affects CLOCK TIME
