Unit 7 The secondary sector

1. The secondary sector Industry Mining Energy production Construction Economic activities that transform raw materials into other products in order to meet human needs Industry Mining Energy production Construction

Industry Transforms raw materials into finishe products or semifinished products Industry needs: - Raw materials - Energy sources - The production factors: worforce, capital and technology

Other activities Mining locating, extrcting and refining the rocks and minerals that are in the ground. It requires: Prospecting methods Extraction techniques (quaries or mines) Refining systems(separate the ore from the gangue) Energy production transforms fuel into forms of energy Construction creates different types of structures and infraestructure

2. Industrial raw materials Raw materials of biological origin Plant raw materials: from agriculture and forestry Animal raw materials: from livestock farming and fishing Raw materials of geological origin  found in deposits in the ground Minerals: used to extract metals, precious metals, and non-metallic materials Rocks: used directly to make products and to manufacturate construction materials Fossil fuels: to obtain energy

3. Sources of energy * Alternative or green sources Traditional sources
