Explain how latitude and longitude are used?

Latitude lines are measured in degrees, beginning at 0 degrees at the Equator and ending at 90 degrees at either the North or South Poles. They run parallel to one another in an east/west direction.

The Prime Meridian, or zero degree longitude line, passes through Greenwich, England. From there, the lines run north/south and converge at the poles. From 0 degrees, the lines are measured in degrees and move east and west until they reach 180 degrees, or the international date line.

One nautical mile separates one minute of latitude from the next, and as longitude converges at the poles, the distance between minutes of longitude varies depending on one's north/south position. One degree is divided into 60 minutes, and one minute into 60 seconds.

Since modern GPS can measure down to decimals of seconds, you can use a point of latitude and longitude and pinpoint yourself to within a meter of your EXACT spot on Earth. Using these, every point on Earth can be described using one latitude and one longitude.

Latitude and longitude are used to specify the geographic coordinates of a location on the Earth's surface. Latitude measures the distance north or south of the equator, while longitude measures the distance east or west of the prime meridian. Together, latitude and longitude provide a precise way to pinpoint any location on Earth's surface, facilitating navigation, mapping, and communication.
