Plan |
1. 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. |
1. A plan is a drawing of a small area on a large scale. |
Ans. 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.
Ans. Symbols give a lot of information in a limited space. With the use of these symbols, maps can be drawn easily and are simple to read. Even if we don’t know the language of an area and therefore cannot ask someone for directions, we can collect information from maps with the help of these symbols. Maps have a universal language that can be understood by all.
Ans. Difference between small scale map and large scale map
small scale map |
large scale map |
When large areas like continents or countries are to be shown on a paper, then we use a small scale. For example 5 cm. on the map shows 500 km. of the ground. It is called a small scale map. |
When a small area like village or town is to be shown on paper, then we use a large scale that is 5 cm. on the map shows 500 metres only on the ground. It is called a large scale map. |
Ans. There are three Components of Maps – distance, direction and symbol.
Distance – Maps are drawn to reduced scales. But this reduction is done very carefully so that the distance between the places is real. Therefore, a scale is chosen for this purpose. 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 village or town is to be shown on paper, then we use a large scale.
Direction - Most maps contain an arrow marked with the letter ‘N’ at the upper right hand corner. This arrow shows the north direction. It is called the north line. When we know the north, we can find out other directions, for example east, west and south.
Symbols - 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. With the use of these symbols, maps can be drawn easily and are simple to read.
