LATITUDE AND LONGITUDE

To find the location of a person or place on the Earth, we can use a precise system of geographical coordinates.

Geograpical coordinates are based on imaginary horizontal and vertical lines that encircle The Earth called parallels and meridians.

Parallels

• Encircle to the equator
• Divides into two halves: northern and southern hemispheres.
• Other parallels: Tropic Cancer, Trpic Capricorn, Artic Circle, Antartic Circle....

Meridians

• Encircle to The Earth vertically.
• Greenwich meridian divides into esatern and western
