30° N is a latitude measure, while 110° W is a longitude one.
Latitude is the angular distance of a geographical point from the equator expressed in degrees. Therefore, latitude expresses a point position in the north – south direction on Earth.
In turn, longitude is the position in the east-west direction, defined as the angle between a great circle through the poles of the earth and an arbitrarily chosen zero meridian. Unlike latitudes, there are no natural reference points, like the North Pole, the South Pole and the equator.
