3. Answer the following questions in not more than 125 words :

(i) Classify maps. Describe these briefly.
OR
Write an explanatory account of types of maps.
Answer: 
Maps are as old as civilisation. The people of ancient civilisation like Hindus, Greeks, RomAnswer:etc. were familiar with art of map-making. However, the earliest maps were rough sketches of local areas. Maps can be classified on the following two bases :

• According to Scale 
• According to Purpose.

(A) According to Scale
1. Small-scale maps. These maps are smaller in size. They have a scale smaller than 1 inch:16 miles. World maps, wall maps and Atlas maps are small scale maps. 
{ MBD Super Refresher Geography-XI ) 
 
2. Large scale maps. These maps show more details as they are larger in size. These have a scale of 6": 1 mile. These show the details of buildings and property.
Thus, maps are of the following four types on the basis of scale:

• Cadastral maps. These show full details of buildings and properties and are known as ‘answer:
• Topographical maps. Survey of Indian department prepares these maps on a scale of 1: 50,000 or 1 inch : 1 mile. These are large scale maps showing the natural and man made features of an area.
• Wall maps. These are small scale maps used for educational purposes.
• Atlas maps. These are small scale maps, bound together in the form of an Atlas. These are best suited for educational purposes. As Time Atlas of world on an R.F. of: 1,000,000.

(B) According to Purpose. Different types of physical and cultural maps are prepared according to their purpose.
1. Physical Maps.

1. Relief maps. These show the relief features, drainage, soil etc. of an area.
2. Geological maps. These show the distribution of different types of rocks in an area.
3. Weather maps. Weather maps show the atmospheric conditions of temperature, pressure winds, rainfall etc at a place at a given time. Indian daily weather maps are prepared at Pune.
4. Vegetation maps. These show the distribution of natural vegetation in an area.
5. Land use maps. These maps show the different uses of land, soils and distribution of crops.
6. Bathymetric maps. These maps show the depth of the oceAnswer:and seas on charts.
7. Astronomical maps. These maps show the position of stars and planets in the sky.

2. Cultural Maps

1. International maps. These maps are prepared on a scale of 1/1,000,000.
2. Political maps. These maps show political boundaries of countries, towns, capitals etc.
3. Population maps. These show the density and distribution of population of an area.
4. Transferor maps. These show roads, railways, ocean routes and air routes.
5. Economic maps. These show the pattern of distribution of various crops, cattle, industry and trade.
6. Linguistic maps. These maps show the distribution of different languages.
7. Ethnographic maps. These maps show the distribution of different races.

Answer: 
A perfect map should have the following essentials :

• Title of the map 
• Scale

Answer: 
The earth is a sphere. A globe is the true representation of the earth. The globe is a small model of the earth. But sometimes, we have to face many problems in using a globe. So it has become necessary to use maps. Generally, maps are preferred to globes for their use for educational purposes :

1. The whole earth cannot be studied from a globe.
2. Globes do not show a large number of details. These can be shown on maps.
3. Distance cannot be measured on a globe because it is a curved surface.
4. A comparative study of two areas is not possible on a globe.
5. Maps can be easily handled.
6. Maps can be easily incorporated in books or bound in atlases.
7. Maps can be drawn to any scale.

Question 6. 
Describe the uses of Cadastral maps. Answer: Cadastral maps are large scale maps which represent small areas of the earth on a large size of paper. These can be drawn on paper, cloth, plastic sheet with greater details.

1. These are property maps which are drawn to demarcate the boundaries of fields, buildings, etc.
2. These are especially prepared by government to realise land revenue and property taxes.
3. The village maps of our country are an example of it.
4. These show details.
5. The city maps for planning may also be included in this category.

Question 7. 
What are Small Scale Maps? Give examples.
Answer: 
Small Scale Maps. These maps represent large areas on a small sheet of paper. These have fewer details such as Atlas and wall maps.
(i) Wall Maps. These maps are generally drawn boldly so that they can be seen from a distance. They are used in classrooms and cater to a larger audience. These maps broadly show very large areas like world as a whole, hemispheres, continents, and countries, states and districts. The scale is smaller than that of topographical maps but larger than atlas maps.

(ii) Atlas maps. The Atlas maps are drawn on a very small scale and give a highly generalised picture of the natural and cultural aspects such as the physical, climatic and economic conditions of different regions of the earth. Only a few atlases are prepared on a 1:1,000,000 scale like the ‘Times Atlas of the World'. The Registrar General of India brings out Census Atlas from time to time. NATMO is a well- known important organisation in our country that publishes all kinds of maps for various purposes depicting different parts of the country.

(iii) Thematic maps are usually prepared on small scale highlighting specific themes such as relief, temperature, and political divisions.

Question 8.

Maps are the major tools of Geography. Maps have been used since ancient times, but they have become indispensable in modern times. Maps serve as key to Geography. Maps are becoming useful in many fields :
