Question: Answer the following questions briefly.

  1. What are the three components of a map?
  2. What are the four cardinal directions?
  3. What do you mean by the term ‘the scale of the map’?
  4. How are maps more helpful than a globe?
  5. Distinguish between a map and a plan.
  6. Which map provides detailed information?
  7. How do symbols help in reading maps?

Answer:

  1. The three components of a map are: distance, direction and symbol.
  2. The four cardinal directions are: North, South, West and East.
  3. The scale of a map is the ratio between the actual distance on the ground and the distance shown on the map.
  4. A globe is useful when we want to study the Earth as a whole. But, when we want to study only a part of the Earth, it is of little help. For this purpose, we use maps. A map can represent the entire Earth’s surface or a part of it.
    Maps can be used to show the physical features of the Earth (mountains, plains, oceans, rivers etc.), the political divisions of the Earth (countries, states, cities, villages etc.), and certain specific information (roads, rainfall, forests, industries etc.)
  5. Map:
    • 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.
    • It can be used for representing large areas like continents or countries (large scale maps), and also for representing a small area like a village or a town (small scale maps).
    Plan:
    • A plan is a drawing of a small area on a large scale.
    • It is used for representing those things that cannot be represented in a map. For example, the length and the breadth of a room cannot be shown in a map. For this purpose, a plan is used.
  6. A large scale map provides detailed information.
  7. As it is not possible to draw on a map the actual shape and size of different features (e.g., buildings, roads, bridges), they are shown by using certain standard letters, shades, colors, pictures and lines. These symbols give a lot of information in a little space. Using these symbols, maps can be drawn easily. The use of symbols makes maps simple to read.

Question: What are cardinal points and intermediate directions?

Answer: The four major directions – North, South, East and West are called cardinal points. Beside these major directions we have four intermediate directions—North-east (NE), South-east (SE), South-west (SW) and North-west (NW). The intermediate directions are very helpful in locating any place more accurately.

Question: Write a note on ‘compass’.

Answer: The direction of a place is traced out with the help of a compass. It is an instrument used to find out main directions. Its magnetic needle always points towards north-south direction.

Compass

Question: Define and discuss ‘distance’ as a component of a map.

Answer: Maps are drawings. They reduce the whole world or a part of it to fit on a sheet of paper. In other words we can say that maps are drawn to reduced scales. But it needs great care while doing this reduction work in order to keep the distance between the real places. It can only be possible when a small distance on paper represents 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 shown on the map. We can understand this with the help of an example. Suppose, the distance between your coaching centre and your school is 8 km. If you show this 8 km distance by 2 cm on a map. It means, 1 cm on the map will show 4 km on the ground. Thus, the scale of your drawing will be 1 cm = 4 km Scale is very important in any map.

If scale is known, calculation of distance between any two places on a map will be easy. A small scale is used to show large areas on a paper like continents or countries. For example, 10 cm on the map shows 1000 km of the ground. A large scale is used to show a small area like a village or town on paper. For example, 10 cm on the map shows 1000 metres only on the ground.

Question: Give an account of ‘direction’ as a major component of a map.

Answer: Direction is an important component of a map. Most maps contain an arrow marked with the letter ‘N’ at the upper right hand comer. This arrow show the north direction. It is called the north line. After knowing the north direction, other directions, east, west and south can be easily found out.

There are four major directions – North, South, East and West. They are called cardinal points. Besides these, there are four intermediate directions. They are north-east (NE), south-east (SE), south-west (SW) and north-west (NW). Location of any place with more accuracy can be possible with the help of these intermediate directions.

Directions

Question: Discuss symbols as a major component of a map.

Answer: Drawing different features such as buildings, roads, etc. in their actual shape and size on a map is perhaps not possible. It is therefore, they are shown by using certain letters, shades, colors, pictures and lines. These are symbols that give a lot of information is a limited space.

With the use of these symbols, maps can be drawn easily and are simple to read. These symbols help us greatly in a situation when 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, known and understood by all. There is an international agreement regarding the use of these symbols, which are known as conventional symbols.
