  • Components of Maps:
    • Distance
    • Distance between places is shown using scales.
    • Scale is the ratio between the actual distance on the ground and the distance shown on the map.
    • When large areas like continents or countries are to be shown on a paper, then we use a small scale.
    • When a small area like your village or town is to be shown on paper, then we use a large scale.
    • Large scale maps give more information than small scale maps.
    • Direction
    • There are four major directions: North, South, East, West. Also known as Cardinal points.
    • Other four directions North-East, North-West, South-East and South-West are known as Intermediate directions.
    • Compass is also used to find directions. Its needles always point to North-South direction.
    • Symbols
    • Certain letters, shapes, colours, pictures and lines are used to represent certain features like buildings, forests, water sources, etc.
