Experiment 03 · Coordinates

Where did the poles go?

Follow latitude and longitude through an unfamiliar view. Learn why the top of a map is not always the North Pole.

5–10 minutes · No preparation needed

Before you unfold

If a map is centered on a different place, must the North Pole still be at the top?

Try it yourself

  1. Open the experiment. Follow the longitude lines toward the geographic poles. A pole on the far side of Earth may be hidden.
  2. Unfold Earth and look for the North Pole and South Pole labels. Follow the geographic grid around them.
  3. Select “Classic orientation” below the map. Notice how the grid and the map’s top and bottom change.
  4. With classic orientation still selected, switch from Plate carrée to Mercator. Read the note below the viewer about its missing polar regions.
