Here's why:

* Latitude: Latitude lines run horizontally around the Earth, with the equator at 0° and the North Pole at 90° North.

* Longitude: Longitude lines run vertically from the North Pole to the South Pole, with the prime meridian at 0°.

Therefore, 88° North latitude would be a circle around the Earth, but it would be missing a longitude value to pinpoint a specific location.

To specify a location, you need both latitude and longitude coordinates.
