Answer: Industries develop only where the factors of location are favourable, and these factors are unevenly distributed.
- Location of industries depends on raw material, power, water, labour, capital, market, transport and government policy.
- These factors are not available equally everywhere; e.g. coal and iron ore are found only in some areas.
- Industries concentrate where these factors are available together, forming industrial regions such as North-Eastern USA, Western Europe and the Mumbai-Pune region.
- Areas with harsh climate, rugged relief, poor transport or lack of capital (deserts, mountains, dense forests) have few industries.
- Therefore the distribution of industries in the world is uneven.
