Answer:
Latitude are the lines parallel with the equator, both above and below.
Longitude are the lines vertical from pole to pole, measured from the Prime meridian.
They are measuring lines used for locating places on the surface of the Earth. They are angular measurements, measured as degrees of a circle. A circle contains 360°. Each degree can be divided into 60 minutes, and each minute is divided into 60 seconds.
One degree of latitude equals 364,000 feet , one minute equals 6,068 feet, and one-second equals 101 feet.
One-degree of longitude equals 288,200 feet, one minute equals 4,800 feet, and one second equals 80 feet.
They are divided into degrees so that we can know the exact location :)
