Latitud and longitude

2. LATITUDE AND LONGITUDE • • •

Maps and globes use imaginary lines called parallels and meridians.

Parallels and meridians cross each other and form a grid.

This grid allow us to locate any point on the Earth’s surface

•

PARALLELS: Imaginary lines that cross the earth from East to West.

•

 EQUATOR: 1.The main parallel, it’s at 0 º 2. It’s at an equal distance from both poles.

3. It’s divides the Earth into two equal parts (Northern Hemisphere and Southern Hemisphere) 4. It’s the widest parallel.  POLES: Are at 90 º.

MERIDIANS: Imaginary lines that run from the North Pole to the South Pole.  PRIME MERIDIAN: It’s at 0º and it’s also called Greenwich Meridian.  OTHER MERIDIANS: Goes from 180º East (E) to 180º West (W) from the Greenwich Meridian.

Allow us to locate a point on the Earth’s surface.

Describe the exact position where a parallel and meridian meet.

They are latitude and longitude.

LATITUDE:1. Distance between any point of the Earth and the Equator.

2. Equator is at 0 º and the poles are at 90 º.

3. We measure it in degrees, minutes and seconds.

4. We add N for the Northern Hemisphere and S for the Southern Hemisphere.

LONGITUDE: 1. Distance between a point on the Earth and the Greenwich Meridian.

2. We measure it in degrees, minutes and seconds.

3. It goes from 0º at the Greenwich Meridian to 180º W or 180º E
