What are four means of transport?

TRANSPORT

The world today is constantly on the move. It is impossible to imagine life without the planes, trains, ships, and cars that transport people and goods, every day. Each of these incredible machines has been specifically designed to travel over land, through the air, and under or over the water.

  • BY ROAD Most road vehicles have an internal-combustion engine, which burns fuel to make the power that turns the wheels. In a car, the engine is usually in the front and drives either the front or the back wheels. In a motorbike, the engine is placed between the two wheels.
  • BY AIR To travel through the air, aircraft must overcome the force of gravity, which pulls them towards the ground. They achieve this with the help of curved wings and rotors, which produce an upward force called lift as they pass through the air.
  • BY RAIL Trains carry large cargoes of people or goods and, as a result, are much more fuel-efficient and produce less pollution than cars and lorries. The fastest trains, such as France’s TGV, have electric motors, but most trains are powered by diesel engines. Trains can be pulled by one locomotive (powered vehicle) at the front, but can have two or even more.
  • BY SEA As a boat’s weight pushes down on the water, the water pushes back with an upward force, called buoyancy, which supports the boat’s weight, allowing it to float. A submarine submerges by filling tanks with seawater to increase its weight. To surface, it uses air to push water out of the tanks.
