Ch – 4 Maps

  • A map is a representation or a drawing of the earth’s surface or a part of it drawn on a flat surface according to a scale.
  • Different types of maps are:
    • Physical Maps
    • Shows natural features like mountains, plateaus, plains, rivers, etc.
    • Political Maps
    • Shows cities, countries, towns, states, etc.
    • Thematic Maps
    • Focus on specific information like roads, railways, rainfall, etc.

  • 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.

  • A sketch is a drawing mainly based on memory and spot observation and not to scale.
  • A plan is a drawing of a small area on a large scale.
