Ex: Iron Bridge can be protected from rusting by galvanizing the iron using zinc.

Zinc coating on any metal is known as galvanizing

This, in turn, robs them of the facilities and opportunities enjoyed by the non-marginalized sections of society.

1.Nearness to the source of raw material : Large quantities of raw materials are needed for industries. Therefore industries are located near the source of raw materials. It saves the cost of transportation.Steel centres are developed where coal and iron are easily available. Jute mills in West Bengal and the cotton textile mills in Maharashtra are located due to the availability of raw materials.

2.Power resources : Coal, oil and water power are the main sources of power. Most of the industries are located near coal fields. Aluminium industries and paper industries are located near hydroelectric stations.

3.Means of transportation: Modern Industries need cheap, developed and quick means of transportation. Cheap means of transportation are required for the movement of workers, raw materials and machinery to the factories.

4.Climate : Stimulating climate increase the efficiency of the labourers. The cotton textile industry required humid climate. The film industry needs good weather with clear blue skies. Similarly the aircraft industry also needs clear weather.

5.Skilled labour : cheap and Skilled labour is  essential for the location of industries. Glass industry at Firozabad and the sports goods industry in Jalandhar are located due to the availability of Skilled labour.

On the basis of raw material used, industries are classified into followings:
(i)Agro based industries:  It uses plant and animal based products as their raw materials. Food processing, vegetable oil, cotton textile, dairy products and leather industries are examples of agro-based industries.
(ii)Mineral based industries:  These are primary industries that use mineral ores as their raw materials. The products of these industries feed other industries. Iron made from iron ore is the product of mineral based industry. This is used as raw material for the manufacture of a number of other products, such as heavy machinery, building materials and railway coaches.
(iii)Marine based industries:  It uses products from the sea and oceans as raw materials. Industries processing sea food or manufacturing fish oil are some examples.
(iv)Forest based industries:  This utilise forest produce as raw materials. The industries associated with forests are pulp and paper, pharmaceuticals, furniture and buildings.

On the basis ownership industries are classified into private sector, public sector, joint sector and cooperative sector.
(i) Private sector industries are owned and operated by individuals or a group of individuals.
(ii) The public sector industries are owned and operated by the government, such as Hindustan Aeronautics Limited and Steel Authority of India Limited.
(iii) Joint sector industries are owned and operated by the state and individuals or a group of individuals. Maruti Udyog Limited is an example of joint sector industry.
(iv) Co-operative sector industries are owned and operated by the producers or suppliers of raw materials, workers or both. Anand Milk Union Limited and Sudha Dairy are a success stories of a co-operative venture.

The major industrial areas of the world are eastern North America, western and central Europe, eastern Europe and eastern Asia.
In India, major industrial regions are Mumbai-Pune cluster, Bangalore-Tamil Nadu region, Hugli region, Ahmedabad-Baroda region, Chhotanagpur industrial belt, Vishakhapatnam-Guntur Belt, Gurgaon-Delhi-Meerut region and the Kollam-Thiruvananthapuram industrial cluster.
