2 Latitude and Longitude
Every single location on Earth is described by 2 numbers: Latitude and Longitude. Latitude and longitude are a type of coordinate system

3 Latitude Definition: Latitude measures the distance in degrees NORTH and SOUTH of the EQUATOR. Latitude lines are horizontal. They look like this: Because they run parallel to the EQUATOR, they are also called parallels. ALL parallels are 360º circles!


5 The Equator The Equator is the imaginary circle found at 0º Latitude- it “splits” the Earth exactly in half, leaving a Northern half and a southern half.

6 Latitude Values Each line of latitude north of that gets higher until you get to 90° N. That is the North Pole. Each line of latitude south of the equator gets higher until you get to 90° S. That’s the South Pole.

7 Special Latitude Lines
1. Tropic of Cancer - found at 23 ½º North of the Equator. 2. Tropic of Capricorn – found at 23 ½ º South of the Equator. 3. Artic Circle – 66 ½ ° North Latitude 4. Antarctic Circle – 66 ½ ° South Latitude Ants on the ground, get it antactic its in the south

8 66.5

9 Where is Polaris??

10 The angle of the North Star, also known as Polaris, EQUALS the NORTH Latitude you are at.


12 How can I find Polaris in the sky?

13 Lets take a bike ride and see what happen.

14 Longitude Definition: Longitude lines measure the distance in degrees EAST and WEST of the PRIME MERIDIAN. Longitude lines are vertical. They look like this: These lines are also known as Meridians.


16 The Prime Meridian The Prime Meridian is a HALF circle that runs from the North pole to the South pole. It is also 0° however it is 0° longitude. It does NOT run all the way around the Earth. The line on the other side is 180°.

17 The Prime Meridian The Prime Meridian divides the Earth into a west half (western hemisphere) and an east half (eastern hemisphere). The 180° line is known as the international date line.
