### Latitude and Longitude

1. Our Mission: Track hurricanes using exact latitude and longitude coordinates.
2. Finding Locations on Earth How could you describe the exact location of a dot on a basketball? Latitude and Longitude make an imaginary grid system on Earth to help find exact locations.
3. Find as many differences as you can between these two diagrams?
4. Latitude Lines… • Drawn East to West, but are used to measure North and South of the Equator. • The Equator is a line of Latitude. • Separates Earth into Northern and Southern hemispheres. • Also called Parallels because they never intersect and run parallel to the equator. • Labeled using N or S • (N) Positive numbers if located in the northern hemisphere. • (S) Negative numbers if located in the southern hemisphere. • RANGE: 0-90 degrees
5. Latitude Lines 0° Equator 90°N North Pole 90°S South Pole 23.5° S Tropic of Capricorn 23.5°N Tropic of Cancer
6. Latitude Lines For example: The tropic of cancer is 23.5°N. What is the range of possible latitude? 0° to 90° N and 0° to - 90° S Label north if in northern hemisphere and south if in southern hemisphere.
7. Longitude Lines… • Drawn North and South, but are used to measure East and West of the Prime Meridian. • The Prime Meridian is a line of Longitude. • Separates Earth into Eastern and Western hemispheres. • Also called Meridians because they are curved and intersect at the poles. • Labeled using E or W • (E) Positive if located in the Eastern hemisphere. • (W) Negative if located in the Western hemisphere. • RANGE: 0-180 degrees
8. Longitude Lines 0° Prime Meridian Longitude lines are curved and meet at the poles.
9. Latitude and Longitude Lines We can put latitude and longitude together to find exact locations on earth’s surface. Example: Milwaukee, Wisconsin  Use latitude to find how far north or south.  Use longitude to find how far west or east. Latitude is always first in your coordinates. 44°N, -89°W

13. Degrees, Minutes, and Seconds  Each degree of latitude and longitude can be divided into minutes (‘) and seconds (“).  Every degree has 60’ minutes of separation  Every minute has 60” seconds of separation.  Arc seconds can be further divided into tenths, hundreds, and even thousandths.
