• question_answer Why should directions and scales be shown on a map?

Directions are important on a map. The letter 'N' or an arrow ($\uparrow$) is the north direction. Then in relation to that the other direction like south, east and west can be found out. Soone can know the direction of one place with respect to another on a map.             Importance of scales in maps?Maps are a reduced representation of the earth or its parts on a flat surface. This reduction in length and size on a map is done in a fixed ratio. For example, we may take a scale of 1 centimetre to represent 1 Kilometre on the map. This scale is maintained throughout the map.
