The three sectors of economy

Here is a simple explanation of the three sectors of the economy.

Primary: we extract raw materials: mining, fishing, farming and forestry.

Secondary: we transform raw materials into manufactured products ready to sell.

Tertiary: services including transportation.

As we said the primary sector has four groups: Farming, Fishing, Mining and Forestry.

Remember: Arable Farming produces CROPS and other products. Irrigated Farming is when the farmers have to water their CROPS. 

Deep-sea Fishing takes place far from the coast and uses big ships. 

A QUARRY is an open mine where coal and minerals are extracted. 

The secondary sector transforms raw materials like wood or metals into manufactured products. Normally this happens in factories. Therefore we have industries. The car industry, the textile industry, toy industry, the steel industry, etc.

The secondary sector became more important after the first industrial revolution which happened around 1784 with the invention of the steam engine. 

A textile factory at the beginning of the XIX Century.

THE SECOND INDUSTRIAL REVOLUTION

Thomas Edison was an important inventor in the second industrial revolution. He invented the light bulb and people started to use electricity in their homes. 

Three things that made possible the SECOND INDUSTRIAL REVOLUTION were:

1. The use of electricity and the invention of the lamp
2. The invention of the telephone
3. The first cars with internal combustion

CLUE: In the secondary sector, different types of products are produced. Some products are used to make other products. This type of products is called an intermediate product.
