Industries are classified on various bases in the following ways. On the basis of raw materials.
1. Agro Based Industries:
These industries use plant and animal-based products as their raw materials.
Example; Food Processing, Vegetable Oil, Cotton Textile, Dairy Products, etc.
2. Mineral-Based Industries:
These are the industries that use mineral ores as their raw materials.
Iron made from iron ore is the product of a mineral-based industry. Cement, Machine Tools, etc. are the other examples of mineral-based industries.
3. Marine Based Industries:
These industries use products from the sea and oceans as raw materials.
Example; Processed Sea Food, Fish Oil manufacturing units, etc.
4. Forest-Based Industries:
These industries use forest products as raw materials.
Example; Pulp and Paper, Furniture and Some Pharmaceuticals industries, etc.2. Explain the Geographical factors which affect the location of industries?
The geographical factors which affect the location of industries
Raw material:
Materials cannot be transported for long distances, so industries are located near the raw material availability.
Power:
Power is the basic for the industry so it’s generated from conventional sources which should be located near the industries.
Labour:
Availability of cheap and skilled labour is more important.
Transport:
Availability of easy transportation always influences the industry location.
Storage and warehousing:
Finished products should be stored at a suitable storage or warehouse till the goods are taken to the market.
Topography:
The selected site should be flat; which is supported by different transport
Climate:
