  1. What is the Primary sector?
    The extraction of raw materials to be supplied to other industries. e.g farming, mining fishing

  3. What is the Tertiary sector?

  5. How can we see the relative importance of a sector in a country?
    The first way is employment. The percentage of the workforce can be put in a pie chart. However not all labor is the same in terms of its Monetary value. For example what a farmer does is important but the monetary value of foods is less than a doctor.

    Wage is thereore compared using GDP and GNI. This shows how much the sector contributes to the overall economic output.
  6. What is the pre - industrial phase?
    This is where the primary sector leads the economy and employs +2/3 of the working population. Agriciuluture is the most important.
  7. What is the inustrial phase?
    The secondary and tertiary factor increase in productivity. At this point the primary sector decreases in importance and the secondary peaks at this stage but does not provide more than half the workforce.
  8. What is the Post industrial phase?
    This is where the tertiary sector is the most important and the primary and secondary factors continue to decline. The quaternary sector begins to appear.

    The sectoral shifts are part and parcel to the development process
  10. What is Primary energy?

  15. Who are the major producers of energy?
    The USA, canadda, western europe, Russia, parts of the middle east.
  16. What is the energy gap?
    This is the difference betweeen the country's rising demand for energy and the ability to produce it. The gap in the UK is being broadened by the diliberate phasing out of fossil fuels.
  17. What are the problems related to countries that have a rising energy gap?
    Countries which have energy then have great political power and have the ability to hold other countries ransom.
  18. Ho energy consumption can be reduced
    • This is important to slow down the energy gap:
    • Insulate homes. 50% of heat is lost through the loft and walls
    • turn comp. off
    • etc.
