Zusammenfassung der Ressource
The secondary sector
- This sector includes convert raw material
into finished or semi-finished products
- Raw materials
- From plants and animals
- Food products
- Can be obtained from
plants and animals
- Textile fibres of plant origin
- The most importants fibres are
cotton, linen and jute. Main
producers are China, USA, Russia
and India
- Textile fibres of animal origin
- The most important is wool, the main
producers of this is Australia and New
Zeland. Silk is very important too,
main producers are China and Japan
- Forest products
- Wood that is used as a raw material in the
cellulose, paper and furniture industries.
Other important products are resin, cork
and rubber
- Minerals
- Minerals that are extracted frome
the earth´s crust through the
process mining
- 3 types:
- Metallic minerals
- Production of iron, copper ad
bauxite, aluminium is extracted
from bauxite which is abundant
in tropical areas. Gold, silver and
mercury are also very important
- Non-metallic minerals
- Includes phosphates and nitrates, important for
chemical and pharmaceutical industries.
Fertilisers are natural phosphates founded in
North Africa, USA and Russia. Others are clay or marble
- Minerals used to
produce energy:
- Coal, petroleum and radioactive
minerals such as uranium
- Energy sources
- Are natural resources that produce the
power required to make products from
raw materials
- Non-renewable energies
- Obtained from fossil fuels
- Coal
- Used as a fuel to obtain electricity in thermal power stations. Also is a
basic raw material, this is extracted by mining. Nowadays it is being
used less because it is more difficult and expensive to extract.
- Petroleum
- Is the most important energy source.
Used as a fuel and raw materialin the
petrochemical industries. Also used to
produce electricity in thermal power
stations and to make vehicle fuels. It can
be located in reservoirs located under
groundand sea floor
- Natural gas
- It is used to produce electricity in
thermal power stations. Usually founded
in oil fields
- Nuclear energy
- Produce through a nuclear reaction called
fission, this reaction splits the atomic nucleus
of a radioactive mineral usually uranium.
Then is carried to nuclear power stations to
produce energy. The problem is that
generates harmful radioactive waste which
damage our health and our ecosistem.
- Renewable energies
- Hydroelectric power
- Produced using the power of water.
The main advantages are that is
clean, cheap and renewable
- Tidal power
- It uses the movement of the tides, waves
and underwater currents to create
electricity
- Wind power
- Obtained from the energy of the wind. The
energy is transformed into electricity
through turbins or wind farms
- Solar power
- Solar panels convert the
sun´s rays into electric and
heat energy
- Geothermal power
- It is obtained from the naturally
occurring thermal energy
beneath the earth´s surface
- Biomass
- Obtained by processing the waste products
of crop and livestock farming and forestry.
The biomass can be converted into biofuels
- Industry
- Industry through history
- Work by craftsmen
- Products were handmade with the help of tools
- The industrial revolution
- From the mid-18th century the handmade
production was replaced by mass
production facilitated by mechanisation
- The second industrial revolution
- From the end of the 19th century industrial
processes became more complex thanks to various
technical innovations
- Types of industry
- Heavy industry
- Here raw materials are transformed into
semi-finished products that are used in
other industries
- Heavy chemical industries
- Raw materials used to produce other
raw materials for other industries
- Metallurgy
- Transforms non-ferrous
minerals into metals and
semi-finished products
- Ferrous metallurgy
- It transforms iron into steel to make
machinery or rails
- Energy producers
- Industries that produce
energy using different
sources
- Capital goods industry
- Uses products from heavy industry as raw
materials to make materials and
machinery to other industries
- Metallurgical processing industry
- It makes industrial machinery for
light and hevay industry
- Cargo transportation industry
- Includes aeronautics industry, naval
industry and the railway industry
- Construction industry
- Makes materials for buildings
and public works
- Aerospace industry
- It makes satellites
and spacecraft
- Light industry
- It makes products
for consumers
- Textile and clothing industry
- It converts raw materials of
animal or plant origin into
fabric. The fabric is used to
make clothing
- Automotive industry
- It manufacturesall types of vehiles, this
industry is dominated by large
multinationals and they share
different parts of the vehicle
- Food industry
- Transforms raw materials
from fishing or livestock
farming and prepares them to
consumption
- Light chemical industry
- It makes cosmetics,
detergents, plastics ...
- Electronics industry
- It manufactures
high-tech products
- Other industries
- There are many industries as there are
products on the market
