    • Urbanisation is the rise in the proportion of people living in towns and cities.
    • in 2007 the worlds Urban population exceeded its rural population.
    • HIC‘s tend to have a lot of urbanisation an example of this is the UK. This is until the cities become too crowded and people decide to move back into countryside areas.
    • In LIC’s such as Nepal and Ethiopia most people still live in rural areas.
    • In NEE’s like china they are experiencing rapid urbanisation.
    • The two main factors causing urbanisation are
      1. rural-urban migration
      2. natural increase
    • Push factors of rural-urban migration are:
      • homes/ jobs being destroyed due to natural disaster
      • automation
      • desertification
      • civil Wars
    • Pull factors of rural-urban migration are:
      • high paid jobs
      • more medical facilities
      • close to family and friends
      • more entertainment
    • Natural increase is when the number of people dying is less than the number of people being born.
    • The major cities in the UK are:
      1. London (biggest population)
      2. liverpool
      3. cardiff
      4. glasgow
      5. edinburgh
      6. birmingham
      7. newcastle
      8. leeds
      9. manchester
      10. belfast
      11. bristol
    • to creat sustainable life in cities we must:
      1. create green space
      2. waste recycle
      3. energy conservation
      4. water conservation
    • Cities encourage and improve public transport to reduce air pollution and traffic congestion.
    • the case study of a NEE is Mumbai which is a mega city in the West coast of India
    • Population density is the average number of people per kilometre, squared. Countries with low population densities are often in hospitable.
    • Scale of forces only have size and vector forces have direction and size speed is scaler and velocity is vector
    • examples of noncontact forces are gravitational, electrostatic and magnetic. Examples of contact forces are friction, air, resistance and tension.
    • Average speed is distance divided by time
    • Vectors are drawn as an arrow in the length of sensor size, and the direction represents the direction
    • Displacement is the distance moved in a straight line. It’s a vector quantity, whereas distance is a scalar quantity
    • Force is a push or a pull acting on an object
