## Maps

A map is a representation or a drawing of the earthâ€™s surface or a part of it drawn on a flat surface according to a scale. The map can be used for various purposes. There are many types of map, some are shown small areas and a few facts and others are shown many facts as a big book. When we combine many maps together we get an atlas. Atlases are of various sizes, measurements drawn on different scales.

### Types of maps

• PHYSICAL MAPS
Maps showing natural features of the earth such as mountains,  plateaus, plains, rivers, oceans etc. are called physical or relief maps.
• POLITICAL MAPS
Maps showing cities, towns and villages, and different countries and states with their boundaries are called political maps.
• THEMATIC MAPS
Some maps focus on specific information; such as road maps, rainfall maps, maps showing the distribution of forests, industries etc. are known as thematic maps

## Components of Maps

There are three Components of Maps â€“distance, direction, and symbol.

### Distance

Maps are drawings. Which reduces the entire world or a part of it to fit on a sheet of paper. This is possible when a small distance on paper presents a large distance on the ground. For this purpose, a scale is used.

Scale is the ratio between the actual distance on the ground and the distance on the map.

Small scale map

When a large area like a continent or country is to be shown on paper then we use a small scale. For example, 5 cm on the maps shows km. Of the ground. It is called a small-scale map.

Large scale map

When a small area like your village or town is to be shown on paper, then we use a large scale that is 5cm. on the map shows 500m only on the ground. It is called a large-scale map.

### Direction

There are four major directions, North, South, East, and West They are called cardinal points.  The other four intermediate directions are north-east (NE), south-east (SE), south-west (SW), and north-west (NW). We can locate any place more accurately with the help of these intermediate directions.

Most maps contain an arrow marked with the letter â€˜Nâ€™ at the upper right-hand corner. This arrow shows the north direction. It is called the north line. When you know the north, you can find out other directions, for example east, west and south. We can find out the direction of a place with the help of a compass. It is an instrument used to find out the main directions. Its magnetic needle always points towards the north-south direction

### Symbol

It is the third important component of a map. It is not possible to draw on a map the actual shape and size of different features such as buildings, roads, bridges, trees, railway lines, or a well. So, they are shown by using certain letters, shades, colours, pictures, and lines These symbols give a lot of information in a limited space. There is an international agreement regarding the use of these symbols.  These are called conventional symbols.

## Use of color

Various colours are used to indicate a specific place. For example,  generally blue is used for showing water bodies,  brown for mountains,  yellow for a plateau, and green is used for plains.

### Sketch

A sketch is a drawing mainly based on memory and spot observation and not to scale. Sometimes a rough drawing is required of an area to tell where a particular place is located with respect to other places. Such a rough drawing is drawn without scale and is called a sketch map.

### Plan

A plan is a drawing of a small area on a large scale. there are certain things which we may sometimes want to know for example the length and breadth of a room, which canâ€™t be shown on a map. At that time, we can refer to drawings drawn to scale called a plan.
