Learn how a flat map is created from the curved surface of a globe! The model includes a terrestrial globe and three map projections—cylindrical, conical and azimuthal—represented on transparent plastic sheets. Simply place the sheets over the globe to see why different types of map projections are used as well as why distortion occurs on a flat map. The entire model is markable for teaching purposes. The blue globe is steel-constructed, 8" in diameter and sits on an aluminum base. Study guide included.
