Settlements


• Settlements are places where people build their homes.

• Settlements can be of two types:

→ Temporary: Settlements which are occupied for a short time are called temporary settlements. Example: The people living in deep forests, hot and cold deserts and mountains.

→ Permanent: Settlements which are made to live in for a long time are called permanent settlements. Example: People build homes to live in.

Rural Settlements

• The villages are rural settlement where people are engaged in activities like agriculture, fishing, forestry, crafts work and trading etc.
• Rural settlements can be compact or scattered.

→ A compact settlement is a closely built area of dwellings, wherever flat land is available. 

→ In a scattered settlement dwellings are spaced over an extensive area. This type of settlement
is mostly found in hilly tracts, thick forests, and regions of extreme climate.

• In rural areas, people build houses to suit their environment.
→ In regions of heavy rainfall - houses have slanting roofs.
→ In regions where water accumulates in the rainy season - houses are constructed on a raised
platform or stilts.
→ In the areas of hot climate - Thick mud walled houses with thatched roofs.

Urban Settlements

• The towns are small and the cities are larger urban settlements.

• In urban areas the people are engaged in manufacturing, trading, and services.

Transport

• Transport is the means by which people and goods move.

→ In India donkeys, mules, bullocks and camels are common. 
→ In the Andes Mountains of South America, llamas are used.
→ In Tibet, yaks are used.

• The four major means of transport are:
→ Roadways
→ Railways
→ Waterways
→ Airways

Roadways

• Roads are most commonly used means of transport especially for short distances.

• Roads are classified into two types: 
→ Metalled (pucca) 
→ Unmetalled (kutcha)

• The plains have a dense network of roads.

• Roads are also present in terrains like deserts, forests and even high mountains. 
→ Manali-Leh highway in the Himlayan Mountains is one of the highest roadways in the world.
• Roads built underground are called subways/under paths. 

• Flyovers are built over raised structures.

Railways

• The railways carry heavy goods and people over long distances quickly and cheaply.

• Today, Diesel and electric engines have largely replaced the steam engines. 

In places super fast trains
have been introduced to make the
journey faster. 

• The railway network is well developed over the plain areas.
• With the advanced technological skills railway lines are also bein laid in difficult mountain terrains also. Howver these are lesser in numbers. 

• Indian railway network is well developed and largest in Asia.

Waterways

• Waterways are the cheapest for carrying heavy and bulky goods over long distances.

• These are mainly of two types 
→ Inland waterways 
→ Sea routes

Inland Waterways

• Navigable rivers and lakes are used as inland waterways.

Airways

• Airways is the fastest way of transport developed in the early twentieth century. 

• It is also the most expensive due to high cost of fuels.

• Air traffic is adversely affected by bad weather like fog and storms. 

• It is the only mode of transport to reach the most remote and distant areas especially where there are no roads and railways.
• Helicopters are extremely useful in most inaccessible areas and in time of calamities for rescuing people and distributing food, water, clothes and medicines.

• Newspapers, radio and television are called mass media as they can communicate
with a large number of people.

Satellites

• The satellites have made communication even faster. 

• Satellites have helped in oil exploration, survey of forest, underground water, mineral wealth, weather forecast and disaster warning. 

• Wireless telephonic communications through cellular phones have become very popular today. 

Internet
