When finding longitude what is your first step?

Answer 1

Longitude refers to the invisible lines across the globe that mark off specific locations. In order to find a line of longitude, it is important to get a map or globe. Look for long lines that are spaced evenly across the globe.

Answer 2

The first step in finding longitude is to establish a reference point called the Prime Meridian, which is located at 0 degrees longitude and runs through Greenwich, England. From there, you measure the east or west angle between the Prime Meridian and the location you are trying to determine the longitude for.
