• Is difficult about trying to represent the globe on a map? – Taking a 3-D object and trying to make it a 2-D
object will always result in distortions of:• Area• Shape• Distance

Making a flat map of the Earth…
• To demonstrate the difficulty of making a flat map of a round surface, make a map out of an orange peel…
• Using a knife, try to peel the orange so that you take the skin off in one piece!
Is like peeling an
orange…
