What is Transport?

The movement of humans, animals, or goods from one location to another is called transport or transportation.

What are the types of transportation?

(Class 5 SST Chapter 9 Important Notes)

Land Transport

Land transport is the process of transport where vehicles (trains, buses, trucks, cars, bicycles, bullock-carts, etc.) move on the land.

Water Transport

Water transport is the process of transport where boats or ships move through water bodies such as a sea, ocean, lake, canal, or river.

Air Transport

Air transport is the process of transport where aircraft (airplane, helicopters, hot air balloon ship, etc.) move through the air.

Roadways – Mode of Land Transport

  • Rail Transport – Passenger trains, Goods trains.
  • Road Transport – Motor vehicles, Animal powered carts, Human-powered vehicles.

Water Transportation

It is used to carry heavy goods for long distances. It is cheaper than road and airways.

Various Modes of Water Transport
  • Manual boats – Sailboats, Paddleboats, Kayaks, etc.
  • Steamboats – Steamers
  • Motorboats – Ferry boats, Powerboats
  • Ships –  Passenger ships, Naval ships, Cargo ships
  • Submarines

Air Transportation

Air transport is the fastest method of transport.

  • Passenger aircraft: Airplanes, Helicopters, Gliders, Parachutes, etc.
  • Cargo aircraft: Cargo planes, Blimps, etc.
  • Space research and defense: Rockets, Missiles, etc.

What are the power sources for transport vehicles?

Man-powered transportation
  • Transport of people and/or goods using human muscle power.
  • For example, cycling, rowing, skating, skiing, etc.

Animal-powered transportation
  • Animal used for pulling or carrying people and/or goods.
  • For example, bullock-carts, donkeys carrying goods, etc.

Engine-powered transportation
  • A mechanical machine is used to power the vehicles. Steam engines, petrol or diesel engines are some examples of the engines.
  • For example, Bus, Car, Train, Airplane, etc.

Steam Engine

The steam engine was one of the most important inventions of the Industrial Revolution. Steam engines were used in all sorts of applications including factories, mines, train engines, and steamboats.
The steam engines also revolutionized transportation.
 
 

Working principle of a steam engine

  • Generation of heat by burning fuel i.e. coal.
  • Heat energy is used to make steam from water.
  • Pressure is created within the steam and steam releases the pressure by doing work.
  • This work is used to perform activities as per the applications.

This whole setup is called the steam engine.

Steam Engine as the power source for Rail Transport

The invention of the Steam engine

  • Thomas Savery from Spain developed the first working steam engine in 1698. It was not efficient and practically usable.
  • Thomas Newcomen from Britain developed a practically usable steam engine in 1711. It was better than Thomas Savery’s engine.
  • James Watt from Scotland repaired and designed an improved steam engine in 1769. It was an efficient steam engine that became very famous and was used widely in various industries, ships, locomotives of that time.

History of Transport

(Class 5 SST Chapter 9 Important Notes)

Since the beginning, humans have been traveling in search of food, water, shelter, for survival, trading, etc. When there were no means of transportation, they walked. Walking barefoot made their journeys difficult and slow.

When learned to create foot coverings (shoes), they walked with ease. They had to carry their loads themselves. So their journeys were still slow and difficult.

With time humans kept on finding ways to make their travel easier and faster.

Using the animals for the transportation

As humans learned to tame the animals. They domesticated the animals and started using them for transportation. They rode on their back and/or kept the loads on them. Horses, donkeys, Oxen, etc were used for this purpose.

Invention of Wheel

(Class 5 SST Chapter 9 Important Notes)

  • The wheel was invented about 5500 years ago.
  • One of the most important inventions of human history.
  • With time, people kept on improving wheel designs.
  • Carts were also made and wheels were attached to them.
  • These carts were pulled by the people or animals.
  • Revolutionized transport.

With time, designs of wheel and carts were improved. Transportation became faster and easier.

Invention of Boats

Since the stone age, primitive boats were developed to travel through the water. Boats were also used for fishing. So water transport is the oldest way to transport.

With the time, designs of boats were improved. Transportation became faster and easier.

Invention of aircraft

(Class 5 SST Chapter 9 Important Notes)

The first hot air balloon was invented by the Montgolfier brothers in 1783.
The first sustained, controlled, and powered the heavier-than-air airplane was invented by the Wright brothers in 1903. This revolutionary aircraft was called the Wright Flyer.
