NCERT Solutions for Class 6 Geography - Maps

Q1. Answer the following questions briefly:
(a) What are the three components of a map?
Ans: The three components of the map are:

1. Distance- Maps are drawings, which reduce the entire world or a part of it to fit on a sheet of paper. Therefore, a scale is chosen for this purpose. Scale is the ratio between the actual distance on the ground and the distance shown on the map
2. Direction- Most maps contain an arrow marked with the letter ‘N’ at the upper right-hand corner. This arrow shows the northern direction. It is called the north line. When you know the north, you can find out other directions, for example east, west and south. 
3. Symbol- 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.  
   

(b) What are the four cardinal directions?
Ans: The four cardinal directions are—North, South, East and West 

(c) What do you mean by the term ‘the scale of the map’?
Ans: 

• Scale is the ratio between the actual distance on the ground and the distance shown on the map. 
• For example, the distance between your school and your home is 10 km. If you show this 10 km. distance by 2 cm on a map, it means, 1 cm on the map will show 5 km. on the ground. The scale of your drawing will be 1cm = 5 km. 
• Thus, scale is very important in any map. If you know the scale, you will be able to calculate the distance between any two places on a map.

(d) How are maps more helpful than a globe?
Ans:  

• Maps provide more information than a globe.
• A globe can be useful when we want to study the earth as a whole.
• But when we want to study only a part of the earth, as in a country or a state, the globe is of little help. In such situations, maps are helpful.
• 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 is impossible to flatten a round shape and scale it. Therefore, maps are more helpful than a globe.
  

(e) Distinguish between a map and a plan.
Ans: 

(f) Which map provides detailed information?
Ans: Large scale maps provide detailed information because of the following reasons.

• Large scale maps are drawn on big-sized papers.
• Maps are of very large size. 
• They have more space to depict more information.

(g) How do symbols help in reading map?
Ans: With the use of symbols maps are more informative and easier to read because of the following reasons:

• The symbols are of the features in true form.
• Language does not put any problem in understanding the feature.
• Even the less educated can understand the information easily.
  

Q2. Tick the correct answer:  
(a) Maps showing the distribution of forests are
(i) Physical map
(ii) Thematic map
(iii) Political map.
(ii) Thematic Map
Ans: (ii) Thematic map
Explanation: Thematic maps focuses on specific pieces of information such as roads, rainfall distribution, forests, etc. 

(b) The blue colour is used for showing
(i) Water bodies
(ii) Mountains  
(iii) Plains.
Ans: (i) Water bodies
Explanation: Blue is synonymous with water. Thus, the colour blue is used to depict water bodies on maps. 

(c) A compass is used
(i) To show symbols.
(ii) To find the main direction.
(iii) To measure distance.
Ans: (ii) To find the main direction
Explanation: A compass is a tool for finding direction. A simple compass is a magnetic needle mounted on a pivot, or short pin. The needle, which can spin freely, always points north. The pivot is attached to a compass card. 

(d) A scale is necessary
(i) For a map
(ii) For a sketch
(iii) For symbols.
Ans: (i) For a map
Explanation: The scale of a map is the relationship or ratio between the actual distance on the land to the distance given on a map. It is necessary to depict the landforms in the right proportion as well as to calculate the actual distance between any two places on the map.
