Key Points

Secondary activities are economic activities that add value to natural resources by transforming raw materials into valuable finished products. This includes manufacturing, processing, and construction industries.

Manufacturing is the process of converting raw materials into finished goods of higher value for sale. It ranges from simple handicrafts to complex processes like assembling space vehicles.

Modern large-scale manufacturing is characterized by specialization of skills, mechanization, technological innovation, complex organizational structures, and an uneven geographic distribution across the globe.

Modern manufacturing relies on mass production, where large quantities of standardized parts are produced by workers performing a single, repetitive task. This contrasts with the older 'craft' method of making custom, expensive items.

Mechanization refers to using machines to accomplish tasks. Automation is the advanced stage of mechanization where tasks are performed without direct human aid, often using computer control systems.

Industries choose locations to minimize costs, considering factors like access to markets, raw materials, labor supply, sources of energy, and transportation facilities.

Industries using cheap, bulky, weight-losing, or perishable raw materials often locate close to the source. Examples include steel, sugar, and cement industries.

These are the benefits and cost savings that industries gain by locating near other industries. This creates linkages and a shared infrastructure, attracting more businesses to the area.

Footloose industries are not dependent on any specific raw material and can be located in a wide variety of places. Their location is often determined by accessibility to road networks.

Industries are classified by size based on capital invested, workers employed, and production volume. The main categories are household (cottage), small-scale, and large-scale industries.

These are the smallest manufacturing units where artisans use local raw materials and simple tools in their homes, often with family help, to produce goods for local markets.

This involves large markets, diverse raw materials, enormous energy, specialized workers, advanced technology, assembly-line mass production, and large capital investment.

Industries can be classified based on the raw materials they use, such as agro-based, mineral-based, chemical-based, forest-based, and animal-based industries.

Industries are classified by their output as either basic industries or consumer goods industries. Basic industries produce raw materials for other industries, while consumer goods industries produce items for direct use.

A basic industry, like iron and steel, produces materials for other factories. A consumer goods industry, like a bakery or electronics manufacturer, makes products sold directly to customers.

Industries are categorized by ownership into the public sector (government-owned), private sector (owned by individuals or companies), and joint sector (jointly managed by public and private entities).

High-tech industry is the latest generation of manufacturing, characterized by intensive research and development (R and D) and a large workforce of skilled professionals (white-collar workers).

Technopolies are regionally concentrated, self-sustained, and highly specialized high-tech industrial complexes. Famous examples include Silicon Valley near San Francisco.
