Canoes and sailing ships

Canoes and sailing ships were advanced early forms of water transport. A canoe was a big log hallowed out on one side to accommodate passengers and goods.It was propelled using oars or paddles. Sailing ships were advanced boats that could be propelled by wind using a sail. The invention of sailing ships promoted trade and exploration

' Describe developments in modern means of transport

' Analyze the impact of modern means of transport

Inventions in Road Transport

The invention of the wheel enhanced the development of the roads. The Romans built straight roads with hard surface all over Europe and North Africa by 300BC. When the Roman Empire fell, the roads were neglected until the 18th Century when engineers in Europe developed better roads.

An illustration of a road under construction

Modes of Transport

The development of roads led to improvement of the modes of transport. This included the development of bicycles, motorcycle and motor vehicle.

ADVANTAGES OF ROAD TRANSPORT

' It is cheaper compared to other forms of transport ' Roads are flexible and link many parts of a country. ' It is faster compared to rail and water transport ' It is the commonest and easiest form of transport. DISADVANTAGES OF ROAD TRANSPORT ' It leads to loss of lives due to high number of accidents on road ' Pollution of air caused by exhaust fumes leads to environmental degradation. ' Vehicles carry limited amount of load ' Roads are restricted to specific areas. ' Construction of roads is expensive.

Impact of Road Transport

Road transport has affected the lives of people in various ways.These include:-

Inventions of Rail Transport

Many engineers were involved in the development of locomotive engine for example in 1829, Stephenson and his son Robert built an engine called rocket, which had a speed of 48km per hour. Over the years there has been an improvement on efficiency and speed of trains.
