They don't at all all your ever going to need this for is for your school assesment.
Lines of latitude and longitude are only shown only maps so as to help people navigate and pinpoint places on Earth with more accuracy.
Lines of latitude Have flatitude. Longitudinal lines Rise like porcupines.

latitude and longitude
Those are called latitude and longitude lines. Latitude lines run east-west, measuring north and south of the Equator. Longitude lines run north-south, measuring east and west of the Prime Meridian. Together, they help determine specific locations on a map.
Latitude lays flat and spiders have long legs
Lines of Latitude encircle the Earth horizontally, and are parallel to the Equator. Lines of Latitude are intercepted by Lines of Longitude. Lines of Longitude run vertically from the North Pole to the South Pole. The Prime Meridian is zero longitude and passes through the Greenwich Observatory, Greenwich, London, England.
Imaginary lines that are used to help locate places and objects are called lines of latitude and longitude. Lines of latitude run east and west around the Earth, while lines of longitude run north and south from pole to pole.
Lines of latitude and longitude help us locate places on maps and globes. Latitude lines run horizontally and measure the distance north or south of the equator, while longitude lines run vertically and measure the distance east or west of the prime meridian. By using these lines, we can pinpoint the exact coordinates of any location on Earth.
If you used a sextant and a marine chronometer you could determine your position and plot this on a map using latitude and longitude. If you did this regularly you would be able to plot your course.
If you knew your latitude was 57 and your longitude was 47, then you could look on a map of the earth and see which line is latitude 57. You could then follow latitude line 57 until you see hit longitude line 47. This would give you the precise location of your whereabouts.
