Maps – CBSE Notes for Class 6 Social
Facts that Matter:
• 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.
• Maps are of different typesâ€”physical maps, political maps and thematic maps.
• Physical maps show natural features of the earth, political maps show cities, towns, countries etc. with their boundaries and thematic maps focus on some particular information such as maps showing distribution of population.
• The three components of maps are distance, direction and symbol.
• A scale is needed to represent a small distance on paper for a large distance on the ground. Thus, scale is the ratio between the actual distance on the ground and the distance shown on the map.
• A small scale map is used to show large areas like continents or countries on a paper.
• A large scale map is used to show a small area like village or town on a paper.
• There are four major directionsâ€”North, South, East and West, known as cardinal points.
• There are four intermediate directionsâ€”north-east (NE), south-east (SE), south-west (SW) and north-west (NW).
• Symbols are used to show features like buildings, roads, bridges, etc. on the map. By using symbols we make the map very informative.
• Maps have a universal language. There is an international agreement regarding the use of these symbols. These are called conventional symbols.
• A sketch map is a rough drawing without scale.
• A plan is a drawing of a small area on a large scale.
