Importance of Maps:

• Maps help us in learning the different aspects of Geography.
• They show us the position of the places in relation to latitudes and longitudes that are drawn on the map.
• They help us in locating the distance from one place to another, time and location.
• They help us in locating the trade centres, routes, slope of the land, rivers, etc.
• They are used by the government for administrative purposes.
• They guide the travellers and also are useful for the army.

Question 5.
Enlist the different types of maps.
Answer:
The different types of maps are:

1. Physical maps,
2. Historical maps,
3. Distributional maps,
4. Topographical maps,
5. Atlas maps,
6. Wall maps.

Question 6.
What are the pillars of maps and why?
Answer:
Distance, direction and conventional signs are the pillars of maps. These are also known as the most essential components of maps. These are the pillars of maps because, without knowledge of them, we won’t be able to read the map correctly.

Question 7.
What do you understand by the conventional symbols?
Answer:
It is not possible to show on the map the actual shape of features such as a building, a well or a tree. So symbols are used to represent various features in maps. With their help, it is easier and quicker to read and understand the maps. They also make the map clearer and easier to be read. As there has been a common agreement all over the world regarding the use of these symbols, they are called conventional symbols.

Question 8.

It means that the arrow is pointing northwards. The arrow is, therefore, called the North Line.

Direction

Question 11.
How does scale of the map help us to study the maps?
Answer:
Scale of the map is a measuring line with the help of which correct distance between various points on a map can be measured. In a scale, there is always a proportion between the dimensions of the map and the actual areas they represent on the earth. It can be a millimetre, a centimetre or an inch to represent a kilometre, a hundred kilometre or even still larger distances.

Scale

Question 12.
What is the importance of the key in a map?
