THE LATITUDE Think of the earth as a ball or a sphere, spinning about an imaginary axis. In the drawing , the ends of the axis are labeled N for North Pole and S for South Pole!"

" Imagine that 180 equally spaced, parallel circles are painted on the earth. The N-S axis of the earth runs right through the center of each circle. The further the circles are from the poles, the larger they are. The two circles that are right at the poles are so small they are actually just points. All these circles are called PARALLELS or LINES OF LATITUDE !"

"The largest circle, the one equally distant from each of the poles, is called the equator . It is called 'zero' degrees latitude. (The '0' is shown in red on the diagram.) The other lines of latitude are numbered from 0 to 90 degrees going towards each of the poles. The ones going from the equator towards the North Pole ( shown in blue ) are 'north' latitude, and each of the numbers is followed by the letter 'N'.

The ones going the other way, from the equator towards the South Pole (you can't see them all, but shown the ones you can see in shocking pink ) are 'south' latitude, and each of the numbers is followed by the letter 'S'. The equator (zero latitude) is the only one without any letter following the number! Notice that the poles are 90 N and 90 S!

Just imagine someone painted 360 equally spaced lines on the surface of the sphere, each line extending from pole to pole.Shown a few of the lines on drawing. Each of the 360 lines is called a MERIDIAN or LINE OF LONGITUDE !" LONGITUDE

“Lines are numbered. The line that passes through Greenwich (a suburb of London, England) is called the PRIME MERIDIAN . Its longitude is 'zero' degrees. Then, going towards the east, the lines are numbered from 1 to 180 degrees;

Going to the west, the lines are also numbered from 1 to 180 degrees, but going the other way. All the 'east'
