Third or fourth dimension?

If a globe is representative of the third dimension, what does a spinning globe represent? As we move through space and time, are we not interacting within the fourth dimension?

Yes, but so what? A point on a sphere (a globe) can be described by three coordinates. If the sphere is spinning, you need three coordinates to locate the spatial location of the point, and a time coordinate to identify the specific time.
