Abstract

A model globe for illustrating time relationships and related concepts includes a global representation of the earth rotatable about an axis simulating the earth's axis of rotation. A cursor assembly is independently rotatable about the axis, and includes a cursor which may be positioned at a desired place on the earth as represented on the model globe. An indicator is coupled to the cursor assembly and displays the rotations position of the cursor about the simulated axis of rotation. The indicator is preferably in the form of a clock, whereby the time over a 24-hour period corresponding to a revolution of the earth about its axis is displayed to correspond to the position of the cursor. The cursor assembly may be locked to the globe so that they may be rotated about the axis in unison, whereby the indicator depicts the passage of time along the longitude of the cursor as the globe rotates. An internal illuminator may be provided to illuminate the globe to simulate the illumination of the earth by the sun.
