Navigating Davey Jones' locker can be tricky if you don't know lines of longitude and latitude.

The most common way to locate specific points on the Earth's surface is to use coordinates called lines of longitude and latitude. It is like placing a grid system over the Earth.



The equator is a line of latitude that is equal distance from the North and South Poles. The equator has the value of 0 degrees, and it is the starting point for measuring latitude. All lines of latitude are parallel to the equator and are often referred to as parallels. Lines of latitude are equally spaced. There are 90 degrees of latitude going north of the equator and another 90 degrees of latitude going south of the equator. The North Pole is 90 degrees north and the South Pole is 90 degrees south.


Lines of longitude run perpendicular to lines of latitude and pass through both poles and are often called meridians. Lines of longitude are like great circles around the Earth. Lines of Longitude do not have a zero degree point. The Earth is divided equally into 360 degrees of longitude, and there are 180 degrees of longitude that are to the east of the Prime Meridian and another 180 degrees to the west of of the Prime Meridian. The International Dateline is located in the middle of the Pacific Ocean on an imaginary line of longitude at 170 degrees. The International dateline separates two consecutive calendar days. For example, on the right side on the the line it can be Monday and on the left side the line it is Tuesday.
