SECTORS
SECONDARY SECTOR
The secondary sector jobs has jobs which transform raw
material into elaborated products. Uses materials that the primary sector has
produced and converts them into finished products. This process is called
manufacturing. Most manufacturing is done in factories.
The main activities that make up this sector are:
Factories or industries – can produce elaborated products with machinery. They
are usually large building where lot of people works a large quantity of
products are produced.
The industry can be classified into:
