The differences between heavy and light industry.
Transcript of The differences between heavy and light industry.
Found near a well educated workforce
Found near good transport links
Found near major markets to reduce transport costs
Some are found in rural areas of small towns Often found in clusters so they can share the location factors
near good universities
near a well educated workforce and transport links
found close to major markets to reduce transport cost
some found in rural areas or small towns Light industry can also be called 'sunrise' and 'footloose', because they have been growing in importance and are 'tied' to their raw materials or power supply. Industrial estates
Science Parks: new high technology industries,research and development e.g software, medicines. Quaternary industries will have close link to universities. If industrial estates, business parks and science parks are on the edge of towns/cities on sites which have not been used for anything else before they are known as GREENFIELD sites. Areas which have been built on before are then re-developed within towns and cities are called BROWNFIELD sites. Mobile Phone Industry Moore's law- every 18 months a high tech product will be replaced by an item that has double the processing power, double the capacity and is half the price. A light industry uses small amounts of light raw materials to produce goods that are light (e.g computers).
The main light industries include electronics and a variety of assembly industries. A heavy industry uses large amounts of bulky raw materials (e.g coal) to produce goods which are heavy. The four main heavy industries were coal mining, iron and steel making, ship building and engineering. Why did the coal and iron/steel industry grow in the 19th and early 20th centuray?
the market-internal & external
available and accessable raw materials near raw materials- because the raw materials are so heavy, it costs too much to carry them long distances, so cement works are found near limestone, brickworks near clay and engineering works near steel.
near a good power supply- many heavy industries began in the 19th centuary, when coal was in the main source of power and, because coal is so bulky, most factories set up on or near coalfields.
near cheap transport- because the raw materials are heavy, cheap transport is needed and railways are often used as, in the past, were canals.
on flat land- heavy industries are often very large and need a large area of flat land to build on. 19th Centuary In the 19th centuary iron and steel works were built near to raw materials and coalfields. This meant they were often inland. In the UK the raw materials became too expensive to produce. Instead, raw materials were brought in from overseas. 20th Centuary In the 20th centuary newer integrated iron and steel plants were built on the coast to reduce the cost of transporting raw materials. However, other countries started producing iron and steel as well and the UK became less competitive in the world market.
