Longitude always in motion relative to one another. For example, the longitudinal difference between a point on the Equator in Uganda, on the African Plate, and a point on the Equator in Ecuador, on the South American Plate, is increasing by about 0.0014 arcseconds per year. These tectonic movements likewise affect latitude. If a global reference frame (such as WGS84, for example) is used, the longitude of a place on the surface will change from year to year. To minimize this change, when dealing just with points on a single plate, a different reference frame can be used, whose coordinates are
Navy Ten Nautical Miler Navy Ten Nautical Miler The Navy Ten Nautical Miler (Navy 10 nm, 11.5 mi) is a run held at Naval Support Activity Mid-South in Millington, Tennessee. It is unique because it is the only race measured in nautical miles as opposed to statute miles.
