1. MAPPING!

2. LOCATING POSITIONS ON EARTH
COORDINATE SYSTEM:
-A system of lines, that you can use to locate any position on Earth.
- assigns every position on earth a pair of coordinates (2 numbers) called latitude and longitude

3. - Latitude: DISTANCE IN DEGREES NORTH AND SOUTH OF THE EQUATOR.
-LINES OF LATITUDE RUN PARALLEL TO THE EQUATOR
latitude

4. -Longitude: Degrees east or west of the prime meridian.
-Lines of Longitude run parallel to the Prime Meridian
-Prime Meridian: Imaginary line running through Greenwich England, from the north pole to the south pole

5. IMPORTANT THINGS TO KNOW ABOUT LATITUDE AND LONGITUDE!
-Work in units of seconds and minutes
-Just like there are 60 seconds in a minute and 60 minutes in an hour, the same goes for latitude and longitude.
For Example: if you see 40o30’20”W, this = 40 Degrees, 30 Minutes and 20 Seconds West

6. -Altitude: The altitude of a heavenly body is its angular height above the horizon of an observer. Fig 1-6 in review book.
-Your latitude= angle of Polaris (North Star)
