What does longitude mean?
They are imaginary lines running north to south from the poles onEarth, e.g. the Prime Meridian. It can also be used to locate aplace on a map. Think of the Pirate remark th…at," X marks the spot". Except whenlooking at a map the X looks more like a + sign. Now think of onestate only, like Kansas. You want to pin point a location in thestate. You would move the + sign, side to side and up and down. Tohelp you draw lines parallel to each other and equally distancedfrom each other across the map and down the map. then number them.0,1,2, etc So now you have a bunch of squares across the state. 2across and 4 down place you in a specific location. 4 across and 2down a totally different place. So what if the +sign was in the middle of one of those squares?Then we build a grid inside the square. Also numbering the squares.So 4 across 2 down square 14, gives us the location we want. Now we take the numbers from all 3 areas we gave numbers to.Vertical lines Horizontal lines and grid boxes. We place them in aspecific order so everyone does it the same way all the time. Nowsomeone checking the numbers later would see 3 sets of numbers. Thenumbers that corresponds to the up and down line is our longitudeline. The line that is side to side is the latitude and the finalnumber corresponds to the box.In geography, longitude refers to the imaginary lines thatbisect the globe through the North and South Poles (the ones thatrun vertically, as opposed to the lines of latitude that runhorizontally, parallel to the equator). The longitude is the angular distance of a place east or west ofthe meridian at Greenwich expressed in degrees and minutes. (MORE)
