SST Guide for Class 7 PSEB Human Environment – Settlements, Means of Transport and Communication Textbook Questions and Answers

I. Write down the answers to the following questions in approximately 1-15 words.

Question 1.
How does agriculture affect human settlement?
Answer:
Man was a nomad in the beginning. He used to look for his food in jungles. But when agriculture developed, he stayed at one place and thus settlements developed.

Answer:
In the earlier times man would stay at the places, where water was easily available. Water fulfils many domestic and agricultural needs. So the early civilization developed near river valleys.

Question 3.

Answer:
It is easy to develop settlement on level surfaces. Here there are facilities of agriculture, means of transportation and communication. That is why most of the cities are in the northern plains of India. But on the uneven surfaces of the mountains there are limitations of rail, road transport, agriculture and as a result business is at a low level.

Land transport includes paths, unmetalled and metalled roads and highways. Roads have been used by man since the earliest times. Land transport develops according to nature of the land. In modem times the use of cemented roads and automobiles has increased the importance of roads. Roads are tiie basis of civilization. Roads link the fields and farms to the factories, factories to markets, and the goods can be delivered right at the door steps of the consumer. Roads can be constructed in inaccessible areas where railways and waterways are not easy to construct.

Question 2.
“Transport and communications are necessary infrastructures for the economic advancement of a country.’ Explain.
Answer:
Transport and communications constitute the infrastructure for the growth and development of agriculture, industry and trade of a country.

1. The production and exchange of agricultural products depend on means of transportation.
2. Developed means of transport are essential for assembling raw material for different industries. The manufactured goods are sent to markets at a low cost of transportation.
3. An efficient system of transport is essential for the growth of trade of country.

As a matter of fact, the developed means of transport are an index of a country’s
economic development. Transport and communications serve as ‘life lines’ of a country’s development. These can be compared to arteries and veins of a nation.

Question 3.
The expansion of the means of transport and communications is shrinking the world. Discuss.

With the modern developments in transportation and communications, man has controlled time and distance. During the past 50 years, the world’s means of transport and communication have been revolutionised. These changes have been marked with more rapid movement from place to place.

The ocean transport has served as a global, unbroken link between distant lands. The development of air transport has reduced the element of time. The major countries of the world are connected by air routes. Air transport has conquered physical barriers. The inter-continental air routes over the oceans have linked different continents. These fast means of transport have brought different areas closer to each other. It appears as if the world is shrinking day by day and we are living in a’smaller world.

Question 5.
What are the factors which affect the development of human settlement?
Answer:
A group of houses is called settlement. Men started moving from villages to cities. There are certain reasons like increase in population, development of business. Agriculture in river valley and industrial development are the main reasons responsible for development of human settlements.

The Main Factors:
1. Availability of water. People mostly love to live at those places where water is easily available. That is why river valleys became birth places of many civilizations
in the world, eg. Indus Valley Civilization. It developed in the valley of Indus river. Here we have got proofs of Kaccha/Pucca houses.

2. Even surfaces. The uneven surfaces do not attract human settlement because :
(a) Transportation is difficult.
(b) Agriculture is difficult.
(c) House construction is difficult.

But even surfaces have many facilities :
(a) It is easy to make roadways and railways.
(b) Agriculture is easy.
(c) The agriculture produced can be easily transported to other places.
(d) Many big cities and metros have developed in plains with even surfaces.

3. Natural beauty. Many cities have developed because of natural beauty. Here tourism is well developed. It is a source of employment for many people. The examples are Kashmir, Goa, Bangalore, etc.

4. Means of transport and communication. The improved means of transportation and communication help in the development of human settlement. It becomes easy to move people and products from one place to another. With communication we can sent messages to any part of the world. Thus, those places develop economically as well as socially.

Question 6.
Explain in detail about the waterways.
Answer:
1. North Atlantic waterway: It is the maximum used waterway. It combines western Europe, U.S.A. and Canada. The maximum trade in the world takes place through this way.

Suez Waterway

2. Pacific Ocean waterway: It combines North and South America with Asia and Australia.

3. Cape way: It was discovered by Vasco-De-Gama in 1498. This way joins western European countries and America with South Asia, Australia, and New Zealand. The importance of Cape way has decreased because of the construction of Suez Canal waterway.

4. Suez Canal waterway: This canal joins the equatorial sea with the Red sea. It joins the European countries with South Asian countries as well as African and Australian continents.

5. Panama Canal way: This canal comes out of Panama Republic. It combines the Atlantic ocean with the Pacific ocean. This lake also results in the coming together of western Europe and eastern U.S.A. with Western U.S.A. and western Asia.

Question 7.
What contribution have the means of transportation towards the development of human settlement?
Answer:
Different means of transport have helped in the evolution of settlements in ahead ways:

1. Two neighbouring settlements or even those found far away from each other became attracted to each other.
2. Trade led to the growth of commercial activities and culture.
3. It led to faster development of transport and communication from the stage of domestication of animals and the invention of the wheel.
4. Roadways provided door-to-door service, railways helped to move a large number of people and goods in bulk. Waterways provided the cheapest means of transport. Air transport is fast though costly also developed side by side.
5. Apart from transport media and other communication networks became crucial links for exchanging knowledge and ideas.
