Satellite has transformed our lives in numerous ways, namely-
(i) Satellites have made communication faster.
(ii) Satellites have helped in oil-exploration, survey of forest, underground water mineral wealth, weather-forecast and disaster warning.
(iii) We can send electronic mails through internet, gather worldwide information
(iv) Wireless telephonic communications through cellular phones are the need of day

Merits: Waterways are the cheapest means of carrying heavy and bulky goods over long distances. Demerits: Waterways are not available everywhere since it requires either sea, oceans, big rivers or big lakes.

(i) The most expensive means of transport among all.
(ii) Air traffic is adversely affected by bad weather very often.
(iii) In case of any casualty, the risk of life and materials are almost hundred percent.

Merits: Roadways are the most commonly used means of transport for short distances. Roadways have also been built in terrains like deserts, forests, high mountains, etc. Demerits:
(i) We cannot send goods in bulk at a time like those in railways.
(ii) High maintenance of roads is required especially after rainy seasons and it is not as comfortable as railways or airways

(i) In the early days people had no means of transport. Whenever they had to go somewhere they walked on foot.
(ii) They used animals to carry their gods.
(iii) Invention of the wheel, made transport easier. With the passage of time different means of transport developed. Modern means of transport save time and energy.

The place where a building or a settlement develops is called its site. The natural conditions for selection of an ideal site are:
(i) favourable climate,
(ii) availability of water,
(iii) suitable land and
(iv) fertile soil.

i) The most commonly used means of transport especially for short distances are roads. They can be metalled (pucca) and unmetalled (kutcha).
ii) The plains have a dense network of roads. Roads have also been built in terrains like deserts, forests and even high mountains. Manali-Leh highway in the Himalayan Mountains is one of the highest roadways in the world.
iii) Roads built underground are called subways/under paths. Flyovers are built over raised structures.

Internet made human's life more comfortable because with the help of internet we can send electronic mails (e-mails), gather worldwide information and interact with people, reserve tickets for railways, airways and even cinemas and hotels sitting at home. With this kind of interconnectivity of people, services and institutions across the world, all humans are a large global society.

In rural areas, people build houses to suit their environment. In regions of heavy rainfall, they have slanting roofs. Places where water accumulates in the rainy season the houses are constructed on a raised platform or stilts. Thick mud walled houses with thatched roofs are very common in areas of hot climate. Local materials like stones, mud, clay, straw etc are used to construct houses.

Mass media is the means of communication which communicate with large number of the people through newspapers, radio and television.

The two merits of railways are
1. Carry people over long distances quickly and cheaply.
2. Carry heavy goods in bulk.

Settlement is a place where people build their homes.

Roadways, railways, waterways and airways are the four means of transport.
