All meridians intersect at the ___________________________.

All meridians intersect at the North Pole. This is because meridians are the lines of longitude that run from the North Pole to the South Pole. Meridians converge at both poles, meaning that at these points, they all meet. The North Pole serves as the defining point where all longitudes equal zero degrees, which is essential for navigation and understanding geographical coordinates.

The Equator, the South Pole, and the Prime Meridian do not serve as intersection points for all meridians. The Equator is a line of latitude and does not affect the longitudinal lines directly. The South Pole acts similarly to the North Pole in that meridians also converge there, but the question specifically asks for where all meridians intersect, making the North Pole the primary and more recognized point for this context. The Prime Meridian is a specific meridian located at zero degrees longitude and does not represent a meeting point for all longitudes.
