Primary activities involve directly extracting resources from nature (like agriculture and mining), whereas secondary activities involve processing these natural resources into finished or semi-finished goods (like manufacturing steel or weaving cloth).
Why are footloose industries called so?
They are called footloose because they are not tied to any specific location based on raw material availability or heavy transportation costs; they can be set up almost anywhere.
What factors influence the location of an industry?
Key factors include access to raw materials, power supply, labor, capital, transport and communication networks, market proximity, and government policies.
